Frequently asked questions
What is the difference from encoding a full URL?+
This tool encodes components (like a single query value), so characters such as & and = are escaped. Encode each part separately when building a URL.
Why did decoding fail?+
Malformed percent sequences cannot be decoded. The tool shows an error so you can correct the input.
Is my input private?+
Yes. Everything runs locally in your browser.
