- [What is the best free PDF splitter?](https://yourhack.ai/answers/best-free-pdf-splitter): The best free PDF splitter is one that works without an account, adds no watermark, and does the splitting on your own device instead of uploading your document.

- [What is a free alternative to PDF24 that does not upload my files?](https://yourhack.ai/answers/free-alternative-to-pdf24): For everyday jobs like merging, splitting and compressing PDFs, browser-based tools that process the file on your own device are a free alternative to PDF24's online tools.

- [How do I convert a WebP image to PNG?](https://yourhack.ai/answers/convert-webp-to-png): Open the WebP file in a browser-based converter and save it as a PNG in one click, with the conversion done entirely on your device.

- [How do I format a SQL query online safely?](https://yourhack.ai/answers/format-a-sql-query-online-safely): Use a browser-based SQL formatter that indents and re-cases the query entirely on your device.

- [How do I compare two JSON files and see the differences?](https://yourhack.ai/answers/compare-two-json-files): Paste both JSON documents into a browser-based JSON diff tool and it compares them structurally, showing which keys and values were added, removed or changed.

- [How do I calculate my GPA from my grades and credit hours?](https://yourhack.ai/answers/calculate-your-gpa-from-grades-and-credits): On the standard 4.0 scale, convert each letter grade to points (A = 4, B = 3, C = 2, D = 1, F = 0), multiply each by the credits for that course, add them up, and divide by total credits. An A in a 3-credit class and a B in a 4-credit class is (12 + 12) / 7, a GPA of about 3.43. A free GPA calculator does the whole table in your browser.
- [How do I calculate how much gas will cost for a road trip?](https://yourhack.ai/answers/calculate-gas-cost-for-a-road-trip): Divide the trip distance by your fuel economy to get the fuel needed, then multiply by the price per gallon or liter. A 400 mile trip in a car that gets 32 mpg needs 12.5 gallons, which is 45 dollars at 3.60 per gallon. A free gas cost calculator runs the numbers in your browser for any distance, economy and price.
- [What is the easiest way to split expenses fairly on a group trip?](https://yourhack.ai/answers/split-expenses-on-a-group-trip): Total everything the group spent, divide by the number of people to get each fair share, then compare that share with what each person actually paid. Whoever paid less than their share owes the difference to those who paid more, and the debts can be settled in just a few transfers. A free group expense splitter does this in your browser with no account.
- [How do I add VAT to a price or take it back out of a total?](https://yourhack.ai/answers/add-or-remove-vat-from-a-price): To add VAT, multiply the net price by (1 + the rate): at 20 percent, 100 becomes 120. To remove VAT from a gross total, divide by (1 + the rate): 120 / 1.2 = 100. Subtracting 20 percent of the gross is the classic mistake, it gives 96, not the true net. A free VAT calculator does both directions in your browser.
- [How long will it take to double my money at a given interest rate?](https://yourhack.ai/answers/how-long-does-it-take-to-double-your-money): Use the rule of 72: divide 72 by the annual return in percent. At 8 percent a year, money doubles in about 9 years; at 6 percent, about 12 years. It is an approximation for compound growth, and a free compound interest calculator gives the exact year-by-year figures in your browser.
- [How much rent can I afford on my salary?](https://yourhack.ai/answers/how-much-rent-can-i-afford): The widely used guideline is to keep rent at or under about 30 percent of your gross monthly income. On 60,000 a year, that is 5,000 a month gross, so roughly 1,500 in rent. A free rent affordability calculator refines that for your actual income and existing debts, entirely in your browser.
- [How do I figure out how much house I can afford?](https://yourhack.ai/answers/how-much-house-can-i-afford): Lenders commonly apply the 28/36 guideline: housing costs at or under 28 percent of gross monthly income, and all debt payments combined under 36 percent. On 7,000 a month gross, that is up to about 1,960 for the mortgage payment, taxes and insurance. A free home affordability calculator turns that budget into an approximate price range using your rate and down payment, all in your browser.
- [How much is a yearly salary per hour, like 60,000 a year?](https://yourhack.ai/answers/convert-annual-salary-to-hourly-rate): Divide the annual salary by 2,080, which is 40 hours a week times 52 weeks. So 60,000 a year is about 28.85 an hour. If you work different hours, divide by your real weekly hours times 52 instead. A free salary to hourly calculator does the conversion in your browser.
- [How much water should I actually drink in a day?](https://yourhack.ai/answers/how-much-water-should-i-drink-a-day): There is no single number that fits everyone, but two common rules of thumb are eight 8-ounce glasses a day, about 2 liters, or half your body weight in pounds expressed as ounces, so a 160 pound person would target around 80 ounces. Needs rise with exercise, heat and body size, and a free water intake calculator personalizes the estimate from your weight and activity, right in your browser.
- [How do I find my target heart rate zone for exercise?](https://yourhack.ai/answers/find-your-target-heart-rate-zone): Estimate your maximum heart rate as 220 minus your age, then train in a percentage band of it: moderate intensity is commonly 50 to 70 percent of max, vigorous 70 to 85 percent. At age 40 the estimated max is 180, so moderate work sits around 90 to 126 beats per minute. A free heart rate zone calculator computes the bands in your browser, including the more personal Karvonen method.
- [What time should I go to bed if I have to wake up at 6:30?](https://yourhack.ai/answers/what-time-should-i-go-to-bed-to-wake-up-rested): Sleep runs in cycles of roughly 90 minutes, and waking at the end of a cycle feels better than being pulled out of the middle of one. Count back five or six cycles from your alarm, 7.5 or 9 hours, and add about 15 minutes to fall asleep: for a 6:30 alarm that means lights out around 10:45 pm or 9:15 pm. A free sleep cycle calculator lists the good bedtimes for any wake-up time, right in your browser.
- [How much protein do I really need per day?](https://yourhack.ai/answers/how-much-protein-do-i-need-per-day): The baseline recommended dietary allowance is 0.8 grams of protein per kilogram of body weight per day, about 0.36 grams per pound, which is roughly 56 grams for a 70 kg adult. People who train hard commonly target more, with sports nutrition guidance often citing around 1.2 to 2.0 grams per kilogram. A free protein intake calculator personalizes the number from your weight and goal, in your browser.
- [How do I calculate my running pace per mile or kilometer?](https://yourhack.ai/answers/calculate-your-running-pace-per-mile-or-km): Divide your total time by the distance. Running 5 km in 30 minutes is 6 minutes per kilometer, which converts to about 9 minutes 39 seconds per mile. A free running pace calculator solves for any of pace, time or distance when you enter the other two, entirely in your browser.
- [How many miles is 10,000 steps?](https://yourhack.ai/answers/how-many-miles-is-10000-steps): For most adults 10,000 steps is roughly 4 to 5 miles, about 6.5 to 7.5 kilometers, because a typical walking stride covers around 2.1 to 2.5 feet. Your exact distance depends on height and stride length, and a free steps to distance calculator personalizes it in your browser.
- [How many cups is 500 grams of flour?](https://yourhack.ai/answers/how-many-cups-is-500-grams-of-flour): All-purpose flour weighs about 120 to 125 grams per US cup when spooned into the cup and leveled, so 500 grams is right around 4 cups. The conversion is ingredient specific, sugar and butter have different densities, and a free cups to grams converter handles each ingredient in your browser.
- [How do I convert my shoe size between US, UK and EU?](https://yourhack.ai/answers/convert-your-shoe-size-between-us-uk-and-eu): The US, UK and EU scales do not line up one to one, and men and women use different numbering within the same region, so the reliable path is to measure your foot length in centimeters and match it against each region chart. A free shoe size converter maps US, UK, EU and centimeter sizes for men and women in your browser.
- [How many fluid ounces is 500 ml?](https://yourhack.ai/answers/convert-ml-to-fluid-ounces): One US fluid ounce is 29.5735 ml, so 500 ml is about 16.9 US fluid ounces. UK imperial fluid ounces are slightly smaller at 28.41 ml, making 500 ml about 17.6 imperial fluid ounces. A free ml to oz converter gives the exact figure either way, right in your browser.
- [How big is an acre in square feet?](https://yourhack.ai/answers/how-big-is-an-acre-in-square-feet): An acre is exactly 43,560 square feet, which is about 4,047 square meters or 0.405 hectares. As a mental picture, it is about three quarters of an American football field including the end zones. A free area converter switches between acres, square feet, square meters and hectares instantly in your browser.
- [How do I remove line breaks from text I copied out of a PDF or email?](https://yourhack.ai/answers/remove-line-breaks-from-pasted-text): Paste the text into a line break remover, which joins the broken lines back into flowing paragraphs on your own device and lets you choose whether to keep blank lines as paragraph separators. It is free, runs entirely in your browser, and the text is never uploaded anywhere.
- [How old is my dog in human years?](https://yourhack.ai/answers/how-old-is-my-dog-in-human-years): The old multiply-by-seven rule is too crude, because dogs mature very fast early and then age at a rate that depends on their size. A common veterinary guideline counts a medium dog first year as roughly 15 human years, the second as about 9 more, and each later year as 4 to 5, with small breeds aging slower and giant breeds faster. A free dog age calculator applies a size-adjusted model in your browser.
- [Is there a free BMI calculator that does not need an app or sign-up?](https://yourhack.ai/answers/free-bmi-calculator-without-an-app): Yes. A browser-based BMI calculator computes your body mass index instantly on the page, using the standard formula of weight in kilograms divided by height in meters squared, with imperial inputs supported too. There is nothing to install, no account, and your height and weight never leave your browser.
- [How do I add fractions with different denominators?](https://yourhack.ai/answers/add-fractions-with-different-denominators): Rewrite both fractions over a common denominator, add the numerators, then simplify. For 1/3 + 1/4, the least common denominator is 12, so 4/12 + 3/12 = 7/12. A free fraction calculator shows the common denominator and the simplified answer step by step, right in your browser.
- [How can I make a QR code for my wifi password?](https://yourhack.ai/answers/make-a-qr-code-for-your-wifi-password): Encode your network details in the standard wifi string format, WIFI:T:WPA;S:YourNetworkName;P:YourPassword;;, and turn that text into a QR code. Phone cameras recognize this format and offer to join the network when scanned. A browser-based QR generator builds the code on your own device, so your wifi password is never sent to a server.
- [How do I generate placeholder images for a website mockup?](https://yourhack.ai/answers/generate-placeholder-images-for-a-mockup): Create dummy images at the exact pixel size your layout needs, either as labeled solid-color blocks or as random stock-style photos. A browser-based placeholder image generator draws a custom-size image with your colors and label text on your own device, and a Lorem Picsum URL builder gives you ready-to-use random photo URLs for quick prototypes.
- [How do I make a favicon for my website without a design tool?](https://yourhack.ai/answers/make-a-favicon-for-your-website): A favicon today is a small set of PNGs, typically 16, 32 and 180 pixels square, linked from your HTML head. The fastest free route is an emoji favicon: a browser-based generator turns any emoji into favicon PNGs at 16, 32, 64 and 180 pixels and gives you the HTML tag to use them, with nothing uploaded. If you already have a logo, resize it to those sizes instead.
- [How do I generate fake user data for testing?](https://yourhack.ai/answers/generate-fake-user-data-for-testing): Use generated dummy profiles instead of real customer records whenever you seed a database, fill a form or build a demo. A browser-based fake data generator creates user profiles with names, emails, addresses and phone numbers and exports them as text or JSON, entirely on your device, so no real personal data is ever involved and nothing is uploaded.
- [Where do I get test credit card numbers for testing a checkout form?](https://yourhack.ai/answers/get-test-credit-card-numbers-for-checkout-testing): Use numbers that pass the Luhn checksum but are not real cards. Card forms validate the number format with the Luhn algorithm, a checksum over the digits, so a Luhn-valid fake number exercises your validation exactly like a real one. A browser-based test number generator creates such numbers locally, for testing only; for end-to-end payment tests, use the sandbox numbers your payment provider documents.
- [How do I check a PDF's page count and metadata without opening it in an editor?](https://yourhack.ai/answers/check-pdf-page-count-and-metadata): A PDF carries information about itself: page count, page dimensions and metadata fields like title, author and the software that produced it. A browser-based PDF info viewer reads all of that from the file on your own device and shows it instantly, so you can inspect a contract or statement without installing anything and without the document ever being uploaded.
- [How do I rotate a photo that saved sideways?](https://yourhack.ai/answers/rotate-a-photo-that-saved-sideways): Rotate the image in 90 degree steps until it is upright and save the result, which writes the corrected orientation into the pixels themselves. Photos often display sideways because the camera stored an orientation flag that some apps read and others ignore. A browser-based rotate tool turns the photo on your own device and downloads the fixed file, with nothing uploaded.
- [How do I blur or pixelate a screenshot before sharing it?](https://yourhack.ai/answers/blur-or-pixelate-a-screenshot-before-sharing): Hide detail by pixelating or blurring the image, or remove sensitive areas entirely by cropping them out, then share the edited copy. Browser-based blur and pixelate tools process the whole screenshot on your own device with an adjustable strength, and a local cropper cuts away regions completely; nothing is uploaded, which matters precisely because the screenshot contains something sensitive.
- [How do I unminify JavaScript so I can read it?](https://yourhack.ai/answers/unminify-javascript-to-make-it-readable): Run the minified code through a formatter, which re-adds line breaks, indentation and brace structure so the logic becomes readable again. Formatting cannot restore original variable names that minification shortened, but it makes the control flow easy to follow. A browser-based JS formatter does this on your own device, so proprietary or internal code is never pasted to a server.
- [How do I format messy HTML so it is readable?](https://yourhack.ai/answers/format-messy-html-code): Run the markup through an HTML beautifier, which indents nested elements consistently so the document structure becomes visible at a glance. This is the quickest way to make minified page source, CMS output or copied markup readable. A browser-based HTML formatter does it instantly on your own device, with nothing pasted to a server.
- [How do I convert variable names between camelCase and snake_case?](https://yourhack.ai/answers/convert-between-camelcase-and-snake-case): Split the identifier at its word boundaries, then rejoin the words in the target style: firstName becomes first_name and back again. A browser-based case style converter does this for whole lists of identifiers at once, converting between camelCase, PascalCase, snake_case, kebab-case and CONSTANT_CASE on your own device, which is handy when moving names between languages like JavaScript and Python.
- [How do I escape a string so I can put it inside JSON?](https://yourhack.ai/answers/escape-a-string-for-json): Backslash-escape the characters JSON reserves: double quotes become \", backslashes become \\, and literal newlines must become \n, since raw line breaks are not allowed inside a JSON string. A browser-based JSON escape tool converts any text into a safe JSON string literal, and unescapes it back, entirely on your own device.
- [How do I pull one value out of a deeply nested JSON object?](https://yourhack.ai/answers/extract-a-value-from-nested-json-with-a-path): Address the value with a path expression that walks the structure key by key, like user.profile.tags[0], where dots step into objects and brackets index arrays. A browser-based JSON path extractor evaluates the path against your document on your own device and returns the value, with a clear error showing where the path stops matching.
- [How do I generate Go structs from a JSON sample?](https://yourhack.ai/answers/convert-json-to-go-structs): Paste a sample of the JSON and generate matching Go struct definitions: exported field names, inferred types, nested structs for nested objects, slices for arrays, and json tags mapping each field back to its original key. A browser-based JSON to Go converter does this instantly on your own device, so API payloads are never pasted to a server.
- [What does my user agent string mean and how do I decode it?](https://yourhack.ai/answers/decode-a-browser-user-agent-string): A user agent string is the identifier a browser sends with every request, packed with historical tokens like Mozilla/5.0 that exist for compatibility rather than accuracy. To decode one, parse it into the browser, engine, operating system and device type it most likely represents. A browser-based user agent parser does that on your own device, reading any UA string you paste.
- [How do I convert an international domain name to punycode?](https://yourhack.ai/answers/convert-a-domain-name-to-punycode): Domains with non-ASCII characters are stored in DNS as punycode: an ASCII encoding that starts with xn--, so münchen.example becomes xn--mnchen-3ya.example. Converting a display name to punycode shows the form DNS and registrars actually use, and converting back reveals what an xn-- domain really displays as. A browser-based punycode converter does both directions offline on your own device.
- [How do I look up what a port number is used for?](https://yourhack.ai/answers/look-up-what-a-port-number-is-used-for): Search the port number against the table of well-known assignments: ports 0 to 1023 are reserved for core services by convention, like 22 for SSH, 80 for HTTP and 443 for HTTPS, with many higher ports having common conventional uses. A browser-based ports lookup searches common TCP and UDP ports by number or service name, offline on your own device.
- [How do I convert an Ethereum address to its checksummed format?](https://yourhack.ai/answers/checksum-an-ethereum-address): Apply EIP-55 checksumming: the letters in the hex address are set to upper or lower case according to a hash of the address itself, producing the familiar mixed-case form. Software that checks the pattern can then catch a mistyped address before money moves. A browser-based EIP-55 tool converts any 0x address to its checksummed form and validates existing mixed-case addresses, entirely on your own device.
- [How do I convert NDJSON to a normal JSON array?](https://yourhack.ai/answers/convert-ndjson-to-a-json-array): NDJSON puts one complete JSON object on each line with no commas or surrounding brackets, so to get a normal array you parse each line and collect the objects into [ ... ] form. A browser-based NDJSON converter does this on your own device, reporting any line that fails to parse, and the reverse tool turns a JSON array back into newline-delimited records.
- [How do I turn a CSV file into SQL INSERT statements?](https://yourhack.ai/answers/convert-csv-to-sql-insert-statements): Map the CSV header row to a column list and each data row to a VALUES tuple, quoting text values safely, which yields ready-to-run INSERT statements. A browser-based CSV to SQL generator does this conversion on your own device: paste the CSV, get INSERT statements with a column list derived from the header, with nothing uploaded.
- [How do I convert CSV data into a Markdown table?](https://yourhack.ai/answers/convert-csv-to-a-markdown-table): Rewrite the rows in pipe syntax: a header row, a separator line of dashes, and one pipe-delimited line per record, which is what GitHub-flavored Markdown renders as a table. A browser-based CSV to Markdown converter does this on your own device, handling quoted fields correctly and aligning the columns so the raw text stays readable.
- [How do I add Article schema markup to a blog post?](https://yourhack.ai/answers/generate-article-schema-json-ld): Add a script tag of type application/ld+json containing an Article object with your headline, author, publication and modified dates, and image, which tells search engines explicitly what the article is and who wrote it. A browser-based Article schema generator builds that JSON-LD from a simple form on your own device, ready to paste into your page.
- [How do I add hreflang tags for a site in multiple languages?](https://yourhack.ai/answers/generate-hreflang-tags-for-a-multilingual-site): For each page, add link rel alternate hreflang tags that map every language and region version to its URL, include an x-default for unmatched visitors, and make sure every version carries the same complete set, itself included. This tells search engines which URL to show users in each language. A browser-based hreflang generator builds the whole tag block from your language-to-URL mapping, locally.
- [How do I keep a page out of Google search results with a noindex tag?](https://yourhack.ai/answers/add-a-noindex-tag-to-keep-a-page-out-of-google): Add a meta robots tag with the noindex directive to the page head, and make sure crawlers can still reach the page, because the tag only works if it can be read. Blocking the page in robots.txt instead does not reliably remove it from results, since a blocked page can still be indexed from links. A browser-based noindex tag generator builds the exact meta tag with the directives you choose.
