About URL Encoder / Decoder
Percent-encode special characters in URLs so they survive HTTP requests, or decode an already-encoded URL back to readable text. Pasting a full query string works too: the tool encodes only the values, not the structure.
Frequently asked questions
When do I need to URL-encode a string?
Whenever a value contains spaces, slashes, ampersands, question marks, or non-ASCII characters and you're putting it into a URL, query parameter, or HTTP header.
What's the difference between encodeURI and encodeURIComponent?
encodeURI keeps the URL structure (slashes, colons, hash). encodeURIComponent encodes every reserved character. This tool uses encodeURIComponent so it's safe for query values.
