Real-world Scenarios

Pro Tips

1
encodeURI vs encodeURIComponent

encodeURI preserves URL structure while encodeURIComponent converts all special characters. Use encodeURIComponent for parameter values.

2
Space Handling

Spaces are typically converted to %20 in URLs, but may become + in application/x-www-form-urlencoded format.

3
Safe Characters

Alphabets, numbers, hyphens (-), underscores (_), periods (.), and tildes (~) remain unencoded.

4
UTF-8 Support

Multi-byte characters are converted to UTF-8 byte sequences first, then each byte is encoded as %XX.

FAQ

The result shows %EB%... format.
Yes, this is standard percent-encoding of UTF-8 bytes. Multi-byte characters will be converted to sequence of %XX.
Can I input a full URL?
This tool uses encodeURIComponent which converts URL structure characters like :// as well. It's best used for parameter value encoding.
Decoding results in garbled text.
This can happen if the original encoding wasn't UTF-8. This tool operates based on the UTF-8 web standard.
Is it secure?
URL encoding is NOT encryption. Anyone can decode it. Never include sensitive information like passwords in URLs.
