About the Base64 tool

Encode text into Base64 or decode Base64 back into plain text, switching direction with a click. Handy for data URIs, config files, tokens and anywhere text needs to travel as Base64.

Does it handle accents and emoji?

Yes. Text is treated as UTF-8, so accented letters and emoji encode and decode cleanly. Everything runs in your browser.
