URL Encoder & Decoder
Encode text into a URL-safe format or decode a percent-encoded URL back to readable text. URLs can only contain a limited set of characters, so spaces, ampersands, question marks and non-ASCII characters must be percent-encoded (a space becomes %20, for example) to travel safely in a link or query string. This tool uses the same encoding rules browsers do, so it is reliable for building API requests, debugging redirect chains or cleaning up tracking-laden links. Choose encode or decode, paste your input, and copy the output. All processing happens in your browser, so nothing is logged or transmitted.
How to use URL Encoder / Decoder
- Paste the text or URL you want to encode.
- Read the percent-encoded output.
- To reverse it, paste an encoded URL and choose decode.
- Copy the result for use in your link or query string.
Frequently asked questions
What is percent-encoding?
Percent-encoding replaces unsafe or reserved characters in a URL with a percent sign followed by two hex digits, for example a space becomes %20. It lets you put arbitrary text into URLs safely.
Which characters get encoded?
Reserved and unsafe characters such as spaces, question marks, ampersands, slashes and non-ASCII letters are encoded, while unreserved characters like letters, digits, hyphen, underscore, period and tilde are left as-is.
When should I decode a URL?
Decode when you receive a URL or query value full of percent codes and want to read the original text, for example turning %40 back into an at sign.
