How URL Decoding Works
URL decoding converts percent-encoded characters back to their original form:
- %20 becomes space
- %3A becomes : (colon)
- %2F becomes / (forward slash)
- %3F becomes ? (question mark)
- %26 becomes & (ampersand)
// Encoded URL:
https%3A%2F%2Fexample.com%2Fsearch%3Fq%3Dhello%20world
// Decoded URL:
https://example.com/search?q=hello world

About URL Decoding
URL decoding converts percent-encoded characters back to their original form.
- Percent Encoding: Characters encoded as %XX hex codes
- UTF-8 Decoding: Multi-byte characters use multiple %XX sequences
- Reserved Characters: :, /, ?, #, [, ], @, !, $, &, ‘, (, ), *, +, ,, ;, = are decoded
- Space Handling: %20 or + decoded to space character
Security Note: Always validate and sanitize decoded input to prevent injection attacks.
