Turn an image into a Base64 data URI string you can embed directly in HTML, CSS, or JSON, so the picture travels inline with your code instead of as a separate file. Load an image and the tool encodes it and shows the full data URI, which you can copy with one click or grab as a ready made img tag or CSS background snippet. Inlining small images this way saves an extra network request, which can speed up pages and is useful for email templates or self contained files. Keep in mind that Base64 makes the data roughly a third larger, so it suits small icons and graphics rather than big photos. Everything is encoded locally in your browser using the file reader, so your image is never uploaded and the string is generated instantly.
It is a text string that encodes the whole image, which you can paste inline into HTML or CSS instead of linking a separate file.
It avoids a separate network request for small images and keeps the image self-contained inside your code.
The encoded text is roughly a third larger than the raw file, so Base64 is best for small images, not large ones.
