About This Tool
Why use Base64 to Image?
Paste a Base64 data URL and see the image it contains, then download it as a real file. The string is validated first — it has to start with data:image/ and contain ;base64, — so a malformed or truncated string tells you straight away instead of silently rendering nothing.
This is the tool you want when you have found an encoded image in a CSS file, an API response, an email source or a log and need to know what it actually is. The download is named from the MIME type in the string itself, so a JPEG comes out as .jpg and an SVG as .svg rather than everything being labelled .png.
Key Benefits
Validated before rendering
The string is checked for a proper data:image prefix and a base64 marker, so a truncated paste shows a clear problem rather than a blank box.
Correct file extension
The download is named from the MIME type in the data URL, so a JPEG is saved as .jpg and an SVG as .svg.
Decoded in your browser
The string is never sent anywhere, which matters when it came from a production log or an internal API response.

Base64 to Image FAQs
Why is nothing showing up?
The string is almost certainly incomplete or missing its header. It must start with data:image/ and include ;base64, before the data. Base64 strings are long, so a partial copy is the usual cause.
Can I paste raw Base64 without the data URL prefix?
No. The prefix is what tells the browser the format. Add data:image/png;base64, in front of the data, substituting the correct type if it is not a PNG.
What file name will the download get?
It is derived from the MIME type in the string, so a data:image/jpeg URL downloads as .jpg and a data:image/svg+xml URL as .svg.
Is the decoded image identical to the original?
Yes. Base64 is a lossless text encoding, so decoding returns exactly the same bytes that were encoded.
