Turn a Base64 String Back Into a File
Base64 is a way to store an image as plain text so it can sit inside HTML, CSS, JSON, or an API response. That is useful while coding, but at some point you need the real file back, to open it, edit it, or save it somewhere. This tool does that decode for you.
Paste a full data URI or just the raw Base64, and the image shows up right away. You do not have to know the format. The tool reads the data URI header, or checks the first bytes of the data, to figure out whether it is a PNG, JPG, GIF, WebP, BMP, or SVG. It even pulls the Base64 out of a CSS or HTML snippet if that is what you have.
Once it is decoded you see the type, dimensions, and size, then download the file with the right extension. It all runs in your browser, so the data never leaves your device.

Frequently Asked Questions
Common questions about decoding Base64 images.
How do I convert Base64 to an image?
Paste a data URI or raw Base64 string into the box. The image is decoded and shown right away, then you can download it.
Do I need the full data URI?
No. A full data URI works, but a raw Base64 string is fine too. When the type is missing, the tool detects it from the data.
Which formats are supported?
PNG, JPG, GIF, WebP, BMP, SVG, and ICO. The image is saved with the matching file extension.
Can I paste a CSS or HTML snippet?
Yes. If you paste a CSS background, an HTML img tag, or other text that contains a Base64 image, the tool finds and decodes it.
Why does it say the data is not valid?
The text either is not proper Base64 or does not decode to an image. Check for missing characters or copied extra text.
Is my data uploaded anywhere?
No. The string is decoded entirely in your browser. Nothing is uploaded, logged, or stored on a server.
