Frequently Asked Questions

>What can I encode??

Any text: paste it in and get the Base64 output instantly. Decoding works the same way in reverse.

>Is Base64 encoding safe for URLs??

Standard Base64 uses + and / which are not URL-safe. If you need URL-safe encoding, use Base64URL (replaces +/ with -_) in your own code after decoding here.
