Why encode text to Base64?

Base64 lets you carry text and binary data through channels that only accept plain ASCII, such as URLs, JSON fields and data URIs. Type or paste your text above and get its Base64 representation instantly, ready to drop wherever you need it.

How it works

The encoder converts your text to Base64 in the browser with full UTF-8 support, so accented letters and emoji survive the round trip intact. Because the work is purely client-side, it is an ideal choice for encoding sensitive strings: nothing is uploaded and your data never leaves your device.

Frequently asked questions

Is my text uploaded when I encode it?
No. Encoding happens entirely in your browser, so nothing is sent over the network. This makes the tool safe for sensitive strings like tokens or credentials.
Does it handle accents and emoji correctly?
Yes. The encoder is UTF-8 safe, so accented characters and emoji are encoded faithfully and decode back to exactly what you typed.
What is Base64 useful for?
Base64 represents arbitrary text or bytes using a safe set of ASCII characters, which is handy for embedding data in URLs, JSON, data URIs and configuration files.
