A SMALL GUIDE
How to use this tool
- Paste text and choose encode or decode.
- Select a URL component, whole URL or form value. Enable one item per line for batches.
- Review the output, then copy or download it. No URLs are opened.
When this tool helps
Prepare query parameters, inspect encoded links or convert form values. Component mode escapes reserved punctuation. Whole-URL mode keeps URL separators. Form mode uses a plus sign for spaces.
Conversion runs in your browser. No account or subscription is required, and downloads have no watermark.
Questions before you start
Which mode should I use?
Choose URL component for one query value or path segment. Whole URL keeps separators such as /, ? and & intact; it cannot infer which punctuation belongs inside a value. Encode those values separately.
Why does decoding report an error?
A percent sign must be followed by two hexadecimal digits, and encoded bytes must form valid UTF-8. Fix the reported item before exporting. A plus becomes a space only in form-value mode.
