Is the Base64 to image converter free to use?

Yes. It’s free and runs in your browser - no signup, no install.

Do I need to strip the data URI prefix?

No. The tool handles both raw Base64 strings and full data URIs like data:image/png;base64,... - the prefix is stripped automatically.

Which image formats are supported?

PNG, JPG, WebP, GIF, BMP, and SVG (when encoded with the correct MIME type or detected by signature).

My Base64 string is very long - can I still decode it?

Yes. For very long strings, you can also upload a .txt file containing the Base64 payload and decode that.

Why does the decoded image look broken?

Usually the Base64 string is truncated or has unexpected characters (e.g. stray quotes, hidden whitespace, or a wrong prefix). Copy the full payload and try again.

Is the decoded image sent to any server?

No. Decoding runs in your browser. Strings and files stay on your device.
