Calculation Logic

This tool uses the browser-native decodeURIComponent method to turn hexadecimal URL escape sequences back into their original characters, such as %20 for a space and %3D for an equals sign.

Everything runs in the current browser tab. No network request is needed, and your URLs, query parameters, access tokens, or personal data are not sent to a server.

FAQ

Is this URL decoder free to use?

Yes. It is free and does not require an account.

Is it safe to decode URLs containing passwords or API tokens here?

Yes. The tool runs locally in your browser and does not upload your input. You should still remove sensitive parameters before copying, screenshotting, or sharing decoded links.

What is the difference between encode and decode?

Encode converts special characters into %XX sequences. Decode reverses that process and restores readable characters.

Why do I get a malformed URI error?

The input usually contains an incomplete percent escape, such as %E0%A4%A, where the byte sequence is cut off.
