Base64 URL Encoder

Encode text to URL-safe Base64 (uses - and _ instead of + and /, no padding) or decode it back to plain text. Also shows standard Base64 for comparison. Runs entirely in your browser — nothing is sent to a server.

URL-safe Base64 replaces + with - and / with _, and omits padding =. Safe to use in URLs and filenames without encoding.
