Text to Base64 and back, live as you type. Emoji and any language work. URL-safe Base64 for JWTs and links too.
Converts as you type, in your browser. Nothing you paste is sent anywhere, so API keys and tokens are safe here.

A way to write any bytes using only 64 safe characters (A–Z, a–z, 0–9, + and /), so data survives places that only accept plain text, like emails, JSON and URLs. It is encoding, not encryption.

The Base64 holds a file, like an image or PDF, not text. This tool decodes text only.
