Paste a Base64 payload to preview the decoded image.
For pure-text payloads use the Text to Base64 tool, or recover an inline asset with Base64 to Image.
Decode a Base64 payload back into a viewable image and download it as the original file. Both raw Base64 and full data:image/...;base64,... URLs are accepted; the data URI prefix is stripped automatically, and the MIME type is read from it when present.
The preview uses your browser's image decoder, so format support depends on the browser. PNG, JPEG, GIF, and WebP render anywhere; AVIF needs a recent Chrome, Firefox, or Safari; SVG renders in every modern browser.
Either the Base64 is corrupted, the MIME is wrong, or the format is unsupported by your browser. Inspect the data URI prefix or try downloading and opening locally.
It is inferred from the MIME type in the data URL. When the prefix is missing, the file falls back to PNG.
Yes. The bytes are returned unchanged, so PNG alpha and GIF/APNG/WebP animation are preserved as long as the rendering element supports them.
The decoder will produce a file, but the preview will be blank because the bytes are not a valid image. Use Base64 to Text instead for non-image payloads.
