URL Decode Online – Free URL Decoder

URL decoder – Free Online Tool

Our free URL Decoder turns percent-encoded text such as hello%20world%21 back into readable form. It is the easiest way to understand long tracking links, redirect URLs and query strings.

What is URL decoder?

URL decoding reverses URL encoding. Every %XX sequence is converted back into the character it represents, so %20 becomes a space and %2F becomes a slash.

Marketing links, redirects and search URLs are often full of encoded characters. Decoding them shows exactly what information the link carries.

How to use the URL decoder

1. Paste the encoded URL or text.
2. Click the decode button.
3. Read the decoded result.
4. Copy it for analysis or editing.

Frequently asked questions

What does %20 mean?

It is the encoded form of a space character.

Why do some URLs contain encoded URLs inside them?

Redirect and tracking services pass the destination link as a parameter, so it must be encoded.

Can decoding break a URL?

Decoded text is for reading. To use it in a link again, encode the values back.
