Base64 encode and decode
Convert text to Base64 and back, with full support for accents and emojis. 100% in your browser.
The conversion runs on your device: no text is sent.
Paste your text to encode it to Base64, or a Base64 string to decode it. The tool handles UTF-8 correctly (accented characters, emojis), unlike a plain btoa.
- Instant encode and decode.
- Full UTF-8 support (accents, emojis).
- 100% local, nothing is transmitted.
