Why examples matter for Base64 URL Decoder

Use this Base64 URL decoder to convert URL-safe Base64 values back into readable text. It is useful for JWT parts, compact web tokens, query-safe encoded strings, and any workflow where regular Base64 decoding is not appropriate because the input uses the URL-safe character variation.
