About this tool

Decode Base64-encoded image data and view or download the result. Accepts both raw Base64 strings and full data URI format (data:image/png;base64,...).

Auto-detects the image format from the data header (JPEG, PNG, GIF, WebP). The reverse of the Image to Base64 tool.

Frequently asked questions

What formats are supported?

Any image format the browser can display: PNG, JPEG, GIF, WebP, SVG. The format is auto-detected from the Base64 data.

Do I need the data:image prefix?

No. You can paste just the raw Base64 string and the tool will auto-detect the format. Adding the prefix works too.

Is there a size limit?

The limit is your browser memory. In practice, Base64 strings up to ~10 MB decode without issues.
