Convert Base64 to an Image Online, Free
Paste a Base64 string or a full Data URI and this tool decodes it back into an image entirely in your browser — nothing is uploaded to a server. It works with or without the data:image/...;base64, prefix.
Rather than trusting a Data URI's declared MIME type (which can be missing or wrong), the actual image format is detected from the decoded bytes themselves — PNG, JPG, GIF, WebP, and BMP are all recognized — so the downloaded file always gets the correct extension.
Why Convert Base64 to an Image?
Debug an API Response
See the actual image behind a Base64 field returned by an API, without writing a script to decode it.
Extract an Embedded Data URI
Pull the real image out of a CSS background-image or inline `<img src>` Data URI to save or inspect it.
Recover an Image from a Database Dump
Turn a Base64 text column back into a viewable, downloadable image file.
Verify an Encoded Image Before Using It
Confirm a Base64 string actually decodes to the image you expect before shipping it in code.
Features
Format Auto-Detected
The real image format is sniffed from the decoded bytes, not just the Data URI's declared type.
Data URI or Raw Base64
Paste a full "data:image/...;base64," URI or just the bare payload — both are accepted.
Paste or Upload .txt
Paste directly, or drop in a .txt file containing the Base64 string.
Validated Before Rendering
Invalid Base64 or non-image data is caught and explained, instead of failing silently.
No Server Upload
Decoding happens entirely in your browser — the string is never sent anywhere.
Instant Download
Download the decoded image with the correct file extension already applied.

FAQ
Is this Base64 to image converter free?
Yes, it is completely free to use with no limits, signup, or account required.
Is my data uploaded to a server?
No. Decoding happens entirely in your browser. The Base64 string is never uploaded or sent to a server.
Do I need to include the "data:image/...;base64," prefix?
No. Paste a full Data URI or just the raw Base64 payload — both are accepted.
How does it know which image format to decode?
The actual format is detected from the decoded bytes' file signature (PNG, JPG, GIF, WebP, and BMP are recognized), not just trusted from a Data URI's declared MIME type, which can be missing or wrong.
What happens if the Base64 string is invalid?
The tool flags exactly what's wrong — invalid characters, incorrect padding, or decoded data that isn't a recognized image format — instead of failing silently.
Can I upload a text file instead of pasting?
Yes. Drag and drop a .txt file containing the Base64 string, or click the upload icon to browse for one.
