Turn a Base64 string back into a viewable image
Images are sometimes embedded in code or data as a long Base64 string or data URL, which is unreadable as text. This tool decodes that string back into a viewable image and lets you download it as a file, so you can see and save an image that was only present as encoded text.
Why images get Base64-encoded in the first place
Base64 turns binary data into plain text so an image can be embedded directly in HTML, CSS, JSON or a stylesheet without a separate file. That is convenient for small images and inline assets, but it means the image is trapped in a wall of characters. Decoding reverses the process, recovering the actual image bytes from the text so you can view or reuse the file.
Decoded locally
The decoding happens in your browser, so an embedded image extracted from private code or data is not uploaded to a service. Paste the Base64 string or data URL, see the image, and download it as a proper file. Nothing is sent anywhere.

Frequently Asked Questions
What is a Base64 image string?
An image encoded as plain text so it can be embedded directly in HTML, CSS or JSON without a separate file. It is unreadable until decoded back into an image.
What is a data URL?
A string that carries the encoded image inline, beginning with a data prefix. This tool accepts both a raw Base64 string and a full data URL.
Is the string uploaded to decode it?
No. The decoding happens in your browser, so an image extracted from private code or data is not sent anywhere.
Can I save the decoded image?
Yes. Once decoded you can download it as a proper image file.
Why would an image be Base64-encoded?
To embed it inline in code without a separate file, which is convenient for small images and avoids an extra network request.
