What is URL Decoding?

URL decoding converts percent-encoded characters back into their original form. For example, encoded spaces, punctuation and Unicode characters can be restored to readable text.

This tool uses the browser's built-in decodeURIComponent() function and then parses the decoded text as JSON.
