How it works
- 1Pick a mode: Encode turns plain text into Base64, Decode turns Base64 back into text.
- 2Type or paste your input — UTF-8 is handled correctly, so emoji and accented characters survive the round trip.
- 3Tick URL-safe if the result needs to live in a URL or filename, then copy the output.
