Frequently Asked Questions

How do I know if text is Base64 encoded?

Base64 encoded text typically contains only letters (A-Z, a-z), numbers (0-9), plus (+), slash (/), and equals (=) for padding. It often looks like random characters and may end with one or two equals signs.

Is the decoding process secure?

Yes, all decoding happens locally in your browser. Your Base64 data is processed entirely on your device and never sent to external servers.

What happens if the Base64 is invalid?

The tool will display an error message if the input is not valid Base64. Make sure the text is properly formatted and contains only valid Base64 characters.

Can I decode Base64 files?

Yes, you can decode Base64 text that represents files. The tool will allow you to download the decoded binary data as a file.
