Image to Base64

Turn a picture into a Base64 data URI to paste straight into HTML, CSS or JSON — no image file needed.

How it works

Choose the output style: a full data URI, the raw Base64 string, a CSS background-image rule, or a ready-made HTML <img> tag.
Base64 makes a file about a third larger, which is why it suits small icons, logos and UI shapes rather than large photos.
The exact MIME type is taken from the file, so the data URI works directly in every browser.
Encoding happens on your device; the image is never uploaded.
