What this tool does
Convert ordinary Unicode text to standard Base64 or recover UTF-8 text from an encoded value. The encoder handles non-ASCII characters and emoji rather than assuming that every character fits in a single byte. Decoding checks the input format and rejects binary data that is not valid UTF-8. Base64 is an encoding format and does not encrypt or protect secrets.
How to use it
Choose encode or decode. Paste text or standard padded Base64, run the conversion and copy the result.
Example
Hello
Encoding this example produces SGVsbG8=.
Can this tool decode arbitrary binary files?
No. It is a text converter. Decoded bytes must form valid UTF-8 text; file and binary conversion are outside its scope.
Where is my text processed?
The bundled tool code processes text in your browser. It does not send or save your input. Extensions and other site plugins may have separate behavior.

Inspect a UTF-8 text value encoded in a payload. Base64 is encoding, not encryption; binary data that is not UTF-8 is outside this text decoder.
How to use it
Enter the source input or select Try example. Review Action. Select Convert Base64 and inspect the result before copying or downloading.

Choose the right tool
Base64 is an encoding, so anyone with the encoded value can decode it. Base64URL uses a different URL-safe alphabet; choose the corresponding tool for URL-safe input.
Limitations and common mistakes
