About Base64URL Encoding
Base64URL is a URL-safe variant of Base64 encoding. It replaces characters that have special meaning in URLs (+ and /) with safe alternatives (- and _), and optionally removes padding characters (=).
- Replaces + with - (URL-safe hyphen)
- Replaces / with _ (URL-safe underscore)
- Padding (=) can be removed as it's recoverable
- Result can be used directly in URLs without encoding
- All processing happens locally in your browser
