About URL Decoder

The URL Decoder is a secure client-side utility designed to translate percent-encoded URL strings back into readable text. When inspecting tracking URLs, redirect links, or API parameters, they are often filled with percent-encoded characters (like %20 or %26). Our decoder converts these back to standard text instantly.

How it Works

Paste your URL or parameter string into the input box and click "Decode URL". The tool decodes the string instantly and displays the readable output, ready to copy.

Key Features

  • Percent Decoding: Converts percent-encoded characters back to text.
  • Robust Parsing: Handles complex parameter strings.
  • One-Click Copy: Easily copy the decoded output.
  • Local Processing: Runs entirely in your browser.
