Frequently asked questions

What is base64 for?

It turns binary image data into plain text, handy for JSON APIs, data URIs and inline embeds that cannot carry binary files.

Does base64 make a file bigger?

Yes, base64 adds roughly a third of the original size, so it is best for smaller images and favicons rather than large photos.

Can I decode a data URI back to an image?

Yes, paste the full base64 string and the tool restores the original image, ready to view and download.
