FAQ

What is URL encoding?

URL encoding converts special characters into a format that can be safely transmitted in URLs. Spaces become %20, and other characters are replaced with their percent-encoded equivalents.

When do I need to encode a URL?

Whenever a URL contains special characters like spaces, &, ?, =, or non-ASCII characters, encoding ensures the URL works correctly in browsers and API calls.

Is my data safe?

Yes! All encoding and decoding happens locally in your browser. Your data is never sent to any server.
