> Encode and decode Base64, Base64URL, and percent-encoded URL text. Full Unicode support, so emoji and accents round-trip safely.

Category: Developer. Interactive: open the canonical URL in a browser to use it. It runs entirely client-side.

## What it does

- Base64, URL-safe Base64, and URL component encoding in one place.
- UTF-8 aware, so non-ASCII text round-trips exactly.
- Swap input and output to reverse the operation in one click.
