URL Encoder / Decoder
Encode or decode URL components. Supports both encodeURIComponent and encodeURI modes.
Common use cases
URL encoding is essential any time you include user-supplied text or special characters in a web address.
Encode query parameters
Safely encode values before appending them to a URL so that special characters do not break the request.
Decode tracking URLs
Paste an analytics or redirect URL to reveal the original destination hidden behind percent-encoded characters.
Debug API requests
Verify that parameters you send to REST endpoints are correctly percent-encoded before they hit the server.
Frequently asked questions
Short answers to the questions people usually have before using the tool.
What is the difference between encodeURI and encodeURIComponent?+
encodeURI leaves characters like : / ? # intact because they are valid URL delimiters, while encodeURIComponent encodes everything except unreserved characters. Use Component mode for query parameter values.
Does this tool handle Unicode characters?+
Yes. Both encoding modes convert Unicode to UTF-8 percent-encoded sequences that any HTTP client can decode.
When should I URL-encode data?+
Whenever you place user-supplied text inside a URL — query strings, path segments, or fragment identifiers — encoding prevents breakage from special characters like &, =, and spaces.
