Base64 Encode/Decode
Convert UTF-8 text to Base64 and decode it while preserving accents and emoji. Your data is processed in your browser.
How to use
- Enter text and select Encode.
- Or paste Base64 and select Decode.
- Copy the result.
How it works
Encoding converts text to UTF-8 bytes before Base64. Decoding uses a strict UTF-8 TextDecoder.
Notes and limitations
- Base64 is not encryption.
- Invalid Base64 or UTF-8 bytes are rejected.
Frequently asked questions
Are accents and emoji preserved?
