Who Uses Base64 to Image
Common reasons to decode a Base64 string.
Backend Developers
Liam receives an image as a Base64 string from an API response and needs to check what it actually looks like.

Frequently Asked Questions
Do I need to include the "data:image/..." prefix?
No. A full data URI works, but a raw Base64 string works too — the format is automatically detected from the file's contents.
Which image formats can be decoded?
JPG, PNG, WebP, GIF, and BMP are auto-detected. Any other declared MIME type in a data URI is respected as-is.
Is my data uploaded to your servers?
No. Decoding happens entirely in your browser — your Base64 data is never sent anywhere.
What happens if the Base64 is invalid?
You will see a clear error message explaining the input could not be decoded, so you can check for typos or missing characters.
Does SVG work with auto-detection?
SVG is supported when included in a data URI with its MIME type declared, since it is text-based rather than binary and is not part of the auto-detection sniffer.
Can I re-encode the image afterward?
Yes. Once downloaded, use the Image to Base64 tool to encode it again if you need the string back.
Is Base64 to Image free to use?
Yes. There is no cost, no subscription, and no account required.
Can I use this on my phone?
Yes, the tool is fully responsive and works in any modern mobile browser on iOS and Android.
