URL-Safe Base64 Encoder
Encode text into URL-safe Base64 using `-` and `_` characters so the result is easier to embed in links and tokens.

Features
URL-safe alphabet
Generate Base64 output without `+` and `/` characters.
Padding control
Include or omit trailing `=` padding depending on your target system.
Token friendly
Useful for URLs, callback data, opaque IDs, and compact payloads.
Privacy first
All processing happens in your browser.
Quick Tips
- •This is especially useful for tokens that will live inside URLs or filenames.
- •Some systems expect unpadded output, while others require `=` padding.
- •Use the regular Base64 encoder when you need the standard alphabet instead.
- •Nothing is uploaded while encoding.
