Frequently asked questions

What image formats can I decode?▾

Any format the browser understands — typically JPG, PNG, GIF, WebP, BMP, SVG.

Can I paste a data URI?▾

Yes. The MIME type and image format are detected automatically.

Why won't my decoded image preview?▾

Either the Base64 string is incomplete (re-copy from the source) or the original encoded content wasn't an image. Check that the source actually came from an image file.

Can I convert the format at the same time?▾

No — Base64 is a lossless transformation, so the output format matches the input. To convert formats (e.g. PNG to JPG), decode first, then use a separate image converter.
