About Url Encode Decode
Free online Url Encode Decode tool.
Url Encode Decode is a developer utility that converts text and links between raw and percent-encoded form in one click. Paste a query string containing spaces, ampersands, plus signs or non-ASCII characters and the tool encodes it so it can be placed safely inside a URL parameter, while decode mode recovers the original readable text instantly. It supports full encode and decode cycles, plus an option that treats plus signs as spaces, which matters when you are debugging form submissions and OAuth redirects. Developers use Url Encode Decode to repair broken API calls, students to understand how browsers pass query parameters, and QA testers to reproduce encoded bug reports. Output appears immediately, copies with one button, and stays on your device because everything runs locally and free of charge.

Frequently Asked Questions
When should I use Url Encode Decode while building an API?
Reach for it whenever a value goes into a query string, a form field or an HTTP header and contains spaces, plus signs, ampersands, slashes or non-ASCII characters. Browsers and servers treat those literally, so an unencoded ampersand silently splits your parameter and breaks the request. Encode before sending, decode after receiving, and use the plus-as-space option when you are reproducing a form submission. Url Encode Decode also helps when a pasted link arrives already encoded and you simply want to read what it says.
Is Url Encode Decode free to use?
Yes. Url Encode Decode is completely free with unlimited use — no account, download or payment required.
Is my data uploaded to a server?
No. Url Encode Decode runs entirely in your browser. Your inputs are never sent to our servers or stored anywhere.
Does Url Encode Decode work on mobile?
Yes. The interface is fully responsive and works in any modern browser on Android, iPhone, tablets and desktops.
