URL Decoder

Decode percent-encoded URLs back to their original readable form. Decode query strings and URL components instantly.

Developer Tools

Quick answer:URL decoding converts percent-encoded characters back to their original form: %20 → space, %26 → &, %3D → =. Use it to read encoded redirect URLs, debug query strings in browser address bars, and inspect encoded webhook payloads from third-party APIs.

Make Sense of Messy Links

We've all copied a link from a massive site like Amazon or Google, only to paste it into an email and see a horrifying block of text packed with '%20', '%3D', and '%26'.

These characters are 'percent-encoded' to make them safe for web servers to read, but they make it utterly impossible for human beings to comprehend what the link actually points to. Our URL Decoder instantly reverses this process, returning dirty URLs back to standard, readable English.

Essential for Debugging

When developers are trying to monitor network traffic or debug why an API request failed, staring at an encoded URL string is maddening.

By dropping the payload into this decoder, you can instantly see the exact JSON or query parameters that were passed to the server, making it drastically easier to find the typo or missing value that broke the system.

Frequently Asked Questions

What does %20 mean?

It is the encoded equivalent of a blank space. Web servers can't handle physical blank spaces in a URL, so they substitute it with '%20' to keep the link unbroken.

Can I break a URL by decoding it?

Visually, no. However, if you decode a complex URL and try to paste the decoded version (with spaces and wild characters) directly into your browser's search bar, the browser might struggle to navigate to it.

What does %3D and %26 mean?

These are extremely common in API calls. '%3D' is the equals sign (=) and '%26' is the ampersand (&). They are used to separate key-value pairs in query parameters.

Does decoding decrypt secure data?

No. URL Encoding is just a syntax-translation to satisfy web server protocols. It is not encryption, and it offers zero security or privacy.

Why do some links get encoded multiple times?

If data passes through several different systems or redirects, sometimes each system applies its own layer of encoding (resulting in things like '%2520'). You may have to hit 'Decode' twice to fully unpack it.

Will my URL data be tracked?

No. Decoding is handled entirely by your own device's processor via simple JavaScript commands. We don't see what you decode.
