Base64 Encode / Decode

Encode or decode Base64 text, in the browser.

● Runs in your browser
Everything runs in your browser — nothing is sent to a server. Full UTF-8 support (Hebrew, emoji).

How it works

Your browser converts the text to UTF-8 bytes and encodes them with btoa (or decodes with atob), so Hebrew, emoji and other non-ASCII text round-trip correctly.
