What is the Base64 Encoder & Decoder?
Convert readable UTF-8 text to Base64 and decode Base64 back to text in your browser. This is useful for data interchange and quick debugging.
How to use it
- 1Keep Base64 selected as the scheme.
- 2Enter plain text to encode or paste encoded text into the decode field.
- 3Copy the corresponding result.
How it works
TextEncoder turns Unicode text into UTF-8 bytes before Base64 encoding. Decoding reverses the process through TextDecoder.
A familiar example
The ASCII text “Hello” encodes to “SGVsbG8=”.
Limitations & notes
- Base64 is an encoding format, not encryption.
- Malformed Base64 cannot be decoded.
