Decode Base64 Data URI strings back into standard, downloadable PNG, JPG, or WebP image files with live preview.
Paste any raw Base64 or Data URI string to view the rendered image immediately.
Automatically identifies PNG, JPEG, SVG, WebP, GIF, and ICO image headers.
Save the decoded binary as a native image file to your local computer.
Decodes untrusted string payloads safely in an isolated browser sandbox without server execution.
The Base64 to Image Decoder extracts the base64 character stream from your input, parses the MIME header, and converts the ASCII string into a Uint8Array binary buffer using window.atob().
It creates a Blob object with the corresponding image MIME type and generates an in-memory Object URL (blob:...) for instant preview rendering.
You can then download the reconstructed binary image file directly to your disk with a single click.
Paste base64 response strings to visually verify profile avatar uploads and document scans.
Recover original asset files from minified stylesheets containing inline data:image URIs.
Convert Base64 BLOB strings from SQL or MongoDB records into viewable photos.
Save inline email header graphics as standalone image files.
No. Softnag accepts both full Data URI strings and raw Base64 character strings.
The tool inspects the MIME type prefix or binary magic bytes (like PNG header 89 50 4E 47) to determine the exact format.
Yes. Browser memory can easily handle large Base64 strings up to several dozen megabytes.
No. All decoding and rendering take place locally in your browser.
Yes. Once decoded, you can export the image as PNG, JPG, or WebP.
Yes, Softnag automatically wraps raw base64 strings with standard image headers.
