FAQFrequently asked questions

Does this image to Base64 converter upload my files?

No. Encoding and decoding run in your browser. The image never leaves your device unless you copy or download the result yourself.

What is the difference between raw Base64 and a data URI?

Raw Base64 is only the encoded bytes. A data URI includes the MIME type prefix, such as data:image/png;base64,..., so it can be used directly in HTML, CSS, or Markdown.

Which image formats are supported?

PNG, JPG, GIF, WebP, SVG, BMP, and AVIF. Very large files over 8 MB are blocked so the browser stays responsive.

Can I convert Base64 back into an image file?

Yes. Paste a data URI or raw Base64 string, then download the reconstructed image. If the MIME type is missing, the tool assumes PNG.
