How to use this tool

Enter ordinary text and choose Encode to produce Base64. Switch to Decode when you have a Base64 string. UTF-8 is used so accents and emoji work. Base64 is an encoding format, not encryption, and is not suitable for protecting private information.

Questions and answers

Does Base64 encrypt information?

No. Anyone can decode Base64; it provides no secrecy.

Can it decode binary files?

No. This text-only tool expects the decoded bytes to represent valid UTF-8 text.
