URL Decoder

About the URL Decoder

URL decoding converts percent-encoded sequences back into readable characters. Use it when you inspect messy query strings from logs, analytics, or copied campaign links.

How to use

1. Paste the encoded string or full query part.
2. Decode it.
3. Read the restored text and verify parameters.

Typical situations

• Reading utm_campaign values with spaces
• Debugging redirect targets
• Checking whether a CMS double-encoded a parameter

Tips

• If decoding once still shows %25 sequences, the value may have been encoded twice.
• Be careful with pasted emails that wrap long URLs onto multiple lines.

FAQ

Why does + become a space? In application/x-www-form-urlencoded contexts, + often means space. Path encoding usually uses %20 instead.
