URL Encoder / Decoder
Runs entirely in your browser · Nothing is sent to our servers
Encode special characters, decode percent-encoded strings, or parse any URL into its components.
Encode mode
Converts unsafe characters into %XX percent-encoded form so the string can travel safely inside a URL. Spaces become %20, & becomes %26, and so on. Use this when building query strings or URL path segments from user input.

How it works
How it works
Percent-encoding (RFC 3986) replaces unsafe characters in URLs with a % followed by two hex digits — for example, a space becomes %20.
Characters that must be encoded include &, =, ?, #, and spaces. Reserved characters like / and : have special meaning and are only encoded when used as data.
encodeURIComponent encodes everything except unreserved characters (letters, digits, -_.!~*'()). It is the right choice for query parameter values. encodeURI leaves URL structure characters intact and is for encoding a full URL.
Parse mode breaks any URL into its protocol, host, port, path, query string, and individual query parameters.
All processing happens in your browser. No data is sent anywhere.
