What is URL Decoding?

URL decoding is the reverse of URL encoding. It converts percent-encoded characters back into their original, human-readable form. When a URL contains sequences like %20 or %26, decoding translates them back to a space and & respectively.

This is essential when reading URL parameters, debugging network requests, or interpreting data that was encoded before transmission.

Common Use Cases

• Debugging URLs: Inspect the actual content of encoded query parameters in browser URLs or server logs.
• API response parsing: Decode encoded values returned in redirects or link headers.
• Log analysis: Read access logs that contain percent-encoded request paths or query strings.
• Data extraction: Retrieve original text from encoded form submissions or URL fragments.

Example

URL encoded input:

Hello%20World!%20%26%20welcome%3Dtrue

Decoded output:

Hello World! & welcome=true
