Encoding & Decoding Tools

Encoding turns data into a form that survives a particular channel: Base64 for embedding binaries in text, percent-encoding for URLs, entities for HTML, hex and binary for low-level debugging. These tools handle each of those conversions in both directions, with UTF-8 handled correctly so Arabic, Hindi and emoji round-trip intact.

They are the tools you reach for while reading a token, fixing a broken query string or checking what a byte sequence actually says. Paste, convert, copy — nothing is sent anywhere.
