What is URL encoding?

URL encoding converts special characters into percent-encoded format (e.g., space → %20) so they can be safely used in URLs.

What is the difference between encodeURI and encodeURIComponent?

encodeURI encodes a full URI but keeps characters like :, /, ? intact. encodeURIComponent encodes everything except letters and numbers.

Is this tool safe for sensitive data?

Yes. All encoding happens in your browser. No data is sent to any server.
