FAQ

Does it support binary files?

No. This version is designed for text content pasted into the browser, not file uploads.

Is Base64 secure?

No. Base64 only changes the representation of data. Anyone can decode it if they have the string.

What happens with invalid Base64 input?

The tool returns an error instead of a decoded result so you can catch invalid input immediately.
