Base64 to Image
Decode a Base64 string or data URI back into a viewable, downloadable image. Need to go the other way? Use Image to Base64.
Base64 or data URI
Image preview
Accepted input
Paste either a full data URI (data:image/png;base64,iVBORw0K...) or just the raw Base64 payload. With a data URI the exact MIME type is preserved; with raw Base64 the tool assumes PNG for the preview and download.
Base64 to Image — FAQ
How do I convert Base64 back to an image?+
Paste a Base64 string or a full data:image/... URI above and the image previews instantly. Click Download to save it as a file.
My Base64 string has no data: prefix — will it work?+
Yes. If you paste raw Base64 without a data URI prefix, the tool assumes PNG and renders it. For other formats, include the proper data:image/<type>;base64, prefix.
Why does my image not show?+
The string may be truncated, not actually image data, or use a different format than assumed. Make sure you copied the entire Base64 value.
Is the image uploaded anywhere?+
No. Decoding happens entirely in your browser; nothing is sent to a server.
