How to Use the URL Decoder
- Paste an encoded component.
- Choose whether plus signs represent spaces.
- Decode and copy the result.
Understanding Your Result
Encoded components and form data use different rules for plus signs. Choose the setting that matches your source.
Review the output before placing it in a document, publishing a file or using it in another application. Keep a copy of your original input so you can compare the result or try different settings. This interface is designed for a focused task: it does not replace a full editor, a professional assessment or the checks required by your destination service.
Working in Your Browser
The built-in URL Decoder processes the data you enter in the current browser tab. Tool input is not submitted to a remote processing service. Clear the interface or close the tab when you finish, especially on a shared device. Downloaded files and copied text remain on your device until you remove them.
For another task, follow the related tool links below or return to all U18-CHAN tools. Related utilities can help you prepare an input or finish a result without installing extra software.
