Frequently asked questions
What can I paste?
Either a full data URI (data:image/png;base64,…) or a bare Base64 string. If there’s no data-URI prefix, the tool assumes PNG.
Which formats are supported?
PNG, JPEG, WEBP, GIF, AVIF, BMP, ICO and SVG. The correct file type is detected from the data URI and used for the download.
Why does decoding fail?
Usually the Base64 is truncated or contains stray characters copied from elsewhere. Make sure you paste the complete string.
Is anything uploaded?
No — decoding runs entirely in your browser.
