What is Base64URL Without Padding?

Encode text to Base64URL format without padding characters, the standard format for JWT tokens. This tool creates URL-safe Base64 strings (using - and _ instead of + and /) and omits the trailing = padding characters. This is the exact format used in JWT token headers and payloads, making it perfect for creating JWT-compatible encoded strings, OAuth tokens, and any URL-safe encoded data that should not include padding.
