URL Encode / Decode

Encode or decode URLs and query strings.

About URL Encode / Decode

URLs and query strings must encode special characters to travel safely through browsers and servers. Encode text for use in links, or decode percent-encoded values back to readable form - instantly and privately. Essential when building OAuth redirect URLs, debugging analytics parameters, and fixing broken links with spaces or ampersands. Processing stays in your browser so query tokens and internal paths are not logged on our side. Pair with JSON and Base64 tools when reconstructing complex API requests during development.
