Frequently asked questions
What characters does URL encoding convert?+
URL encoding converts characters that are not allowed in URLs, including spaces, ampersands, question marks, and non-ASCII characters. Each is replaced with a percent sign followed by its hex code.
Is my data processed on a server?+
No. Encoding and decoding runs entirely in your browser. Your text never leaves your device, so you can safely encode API keys, tokens, or any sensitive query parameters.
What is the difference between encodeURI and encodeURIComponent?+
encodeURI encodes a full URL but leaves characters like : / ? # intact. encodeURIComponent encodes everything, making it safe for individual query parameter values.
Can I decode a full URL with multiple parameters?+
Yes. Paste the entire URL and the tool will decode all percent-encoded characters, making the query string human-readable again.
