About this tool
Encode text or files to Base64 and decode back, with proper UTF-8 handling so multi-byte characters survive the round trip.
How it works
- Paste text into either panel; the other side updates live.
- Toggle URL-safe mode to swap +/ for -_ and drop padding.
When to use it
- Embedding a small image or SVG in a data URL.
- Debugging JWTs (though tokens are more than just Base64).
- Passing binary through a JSON API safely.
