How it works

Encoding converts your text to UTF-8 bytes and then to the 64-character Base64 alphabet, so emoji and accented characters survive the round trip. Decoding reverses the process and reports an error if the input is not valid Base64.

Frequently asked questions

Is Base64 encryption?

No. Base64 is an encoding, not encryption — anyone can decode it. Use it to move binary-ish data through text channels, never to protect secrets.

What is URL-safe Base64?

URL-safe Base64 replaces + and / with - and _ and drops the = padding, so the value can be dropped straight into a URL or filename.
