FAQ

Base64 to File questions

See how privacy works

Is Base64 to File free to use?

Yes. This tool is free to use in your browser and does not require an account.

Are my files private?

Base64 to File uses native Base64 in the browser. Selected files are processed locally when the required browser features are available, while application, library, model, security, and limited analytics requests may load separately.

What limits should I know about?

No file upload needed. Very large, encrypted, damaged, or unusual files may not be supported by every browser.

How do I choose the decoded file type?

A data URL can provide its MIME type automatically. For raw Base64, use an output filename with the extension that matches the original content.
