URL Decoder
Decode a percent-encoded URL back into readable text.
This URL Decoder reverses percent-encoding, turning a URL-encoded string full of %XX sequences back into its original readable text. Paste an encoded string, such as a query parameter or redirect URL, and the decoded result appears instantly. Decoding happens entirely in your browser, so nothing is transmitted anywhere.
How to use
- 1Paste a URL-encoded string into the input.
- 2The decoded result updates automatically.
Frequently asked questions
What does a URL decoder do?
It reverses percent-encoding, converting %XX escape sequences back into their original characters — turning something like "hello%20world" back into "hello world".
Why would I need to decode a URL?
Reading a query parameter's real value from a server log, understanding a long redirect URL, or inspecting a link that's been encoded by another tool before you edit it.
What if the string isn't valid percent-encoding?
Malformed sequences (like a stray % not followed by two hex digits) will cause decoding to fail — this tool decodes standard percent-encoding, not arbitrary text.
Is my pasted URL sent anywhere?
No. Decoding happens entirely in your browser, so nothing is transmitted anywhere.
