What Base64 is

Base64 is a way to write binary or text using only letters, numbers, plus, and slash. APIs, email, and data URLs use it often.

How to use it

Choose encode or decode, paste your text, and copy the result. Invalid Base64 is flagged so you can correct it.

Questions

Is this encryption?

No. Base64 is encoding, not a lock. Anyone can decode it.

Can I encode a file?

This tool is for text. For files, use a dedicated file encoder.
