How to use the URL Decoder Online

Web addresses encode special characters as percent codes — spaces become %20, and non-English text becomes long %XX sequences. When you copy a link full of these codes, it is unreadable. This tool lets you decode URL encoded text online in one click, restoring the clean original characters. Bloggers, students and marketers use it to read shared links, and the Encode mode does the reverse when you need a valid URL.

  1. Paste the encoded URL or text into the input area.
  2. Make sure "URL Decode" is selected in the Method dropdown.
  3. Click Convert to see the readable decoded text.
  4. Use "URL Encode" mode when you need to make text URL-safe instead.
  5. Click Copy to use the result, or Clear to decode another link.

Formula

Worked example

Input "hello%20world%21", method URL Decode, click Convert. Output: "hello world!". A long encoded Urdu slug like "%D8%B3%D9%84%D8%A7%D9%85" decodes back to readable "سلام" just as easily. Switch to Encode mode when you need to make links with spaces or special characters safe to share.
