Base64 to Image
Decode Base64 strings back to image files
Base64 to Image decodes a Base64 string or data URL back into real image bytes, verifying the decoded data actually matches a known image file signature (PNG, JPEG, GIF, WebP, or SVG) before handing it back — not just checking that the text looks like Base64.
How to use Base64 to Image
- 1
Paste your Base64 string or data URL.
- 2
Click "Convert" to decode it.
- 3
The tool verifies the decoded bytes are a real image.
- 4
Download the resulting image file.
Everything you need to know about decoding Base64 to images
What does this do?
Takes a Base64-encoded string — the kind embedded in HTML, CSS, or a JSON API response — and decodes it back into a normal, downloadable image file.
When you actually need this
- Extracting an image from an API response that returned it as a Base64 string instead of a file.
- Recovering an image embedded in code (a `data:` URL in CSS or HTML) as an actual file you can open or share.
The reverse tool
If you're starting from an image file and need the Base64 string instead, Image to Base64 does the opposite conversion.

Frequently Asked Questions
What happens if I paste text that isn't actually an image?
It's rejected — the decoded bytes are checked against real image file signatures, so text that happens to look like valid Base64 (such as an English sentence) won't silently produce a corrupt "image" file.
Do I need to paste the full data:image/png;base64,... prefix, or just the Base64 part?
Either works — if there's no data: prefix, it defaults to treating the content as PNG.
Which image formats does this recognize?
PNG, JPEG, GIF, WebP, and SVG — each identified by its real file signature, not just its claimed MIME type.
Does this tool send my data to a server?
Yes — it's sent to our servers to decode and verify, and the result is returned to you; nothing is stored.
Is this tool free to use?
Yes — completely free, with no signup required.
