URL Encoder/Decoder
Encode and decode URL components. Convert special characters to percent-encoded format or decode them back to readable text.

- Or paste an encoded URL to decode it back to readable text.
- Choose between encodeURIComponent (for query params) or encodeURI (full URL).
- See the encoded/decoded result in real-time.
- Copy the result to your clipboard.
Frequently Asked Questions
What is URL encoding?
URL encoding replaces special characters (spaces, &, =, etc.) with percent-encoded values (%20, %26, %3D) so they can be safely included in URLs.
What is the difference between encodeURI and encodeURIComponent?
encodeURI encodes a full URL but preserves special URL characters (://?#). encodeURIComponent encodes everything, making it suitable for query parameter values.
When should I URL encode?
Encode text when including it in URL query parameters, form data, or any context where special characters could break the URL structure.
