About this Base64 encoder
Use this Base64 encoder and decoder for local text conversion, quick payload inspection, and small debugging tasks involving encoded strings.
Common use cases

- Encode sample text before using it in tests or documentation.
- Inspect copied strings without sending them to a server.
How to use this tool
- Paste plain text or a Base64 string into the input area.
- Choose Encode for plain text or Decode for Base64 content.
- Copy the converted output after confirming the status message.
Example
Input

Common errors
- Decode failures often mean the input contains characters outside the Base64 alphabet.
- Missing padding can still work in some contexts, but malformed content may fail.
- Base64 is not encryption, so decoded content should not be treated as protected.
