About URL Encode / Decode
URL encoding (percent encoding) converts special characters to %XX format safe for URLs. Spaces become %20 (or +), ampersands %26, etc. Required because URLs can only contain specific ASCII characters.
The encoder handles both URL components (paths, query strings) and form data. Decoding reverses the process, converting %XX sequences back to original characters. Essential for web development, API work, and handling user input in URLs.
All encoding/decoding uses browser's native encodeURIComponent/decodeURIComponent functions. No data is transmitted, safe for handling URLs with sensitive parameters or API keys.
Frequently asked questions
Encode when putting special characters in URLs: spaces, ampersands, question marks, non-ASCII characters, etc. Always encode query parameter values and form data before constructing URLs.
encodeURIComponent encodes more characters (including /, ?, &) for query parameters. encodeURI preserves URL structure characters for encoding complete URLs. This tool uses encodeURIComponent for maximum safety.
In URLs, %20 is standard percent encoding. In form data (application/x-www-form-urlencoded), + is allowed for spaces. Both decode correctly; modern usage prefers %20 for clarity.
