Frequently asked questions
- Why did a plus sign become a space?
- Only form-value decoding treats plus as a space. URL component and full URL modes keep literal plus signs.
- Does this repair broken percent escapes?
- No. Malformed escapes and invalid UTF-8 produce an error instead of a guessed correction.
- Does the tool visit the URL I enter?
- No. It transforms the string entirely in your browser.
