FAQ

Is Base64 encryption?

No. Base64 is reversible text encoding, not security. Do not use it to hide passwords, tokens, or private keys.

Does this upload my text?

No. Encoding and decoding happen in your browser with JavaScript.

Why is Base64 output larger?

Base64 commonly adds about one third more size because every 3 bytes become 4 text characters.
