Frequently Asked Questions

What is URL encoding?

URL encoding converts special characters to percent-encoded format (e.g., space becomes %20). This ensures URLs work correctly with characters that have special meaning.

Which characters need encoding?

Spaces, &, =, ?, /, #, and non-ASCII characters need encoding in URLs. Reserved characters have special meanings in URLs and must be encoded if used as data.

What is the difference between encodeURI and encodeURIComponent?

encodeURI keeps URL structure intact (doesn't encode /, ?, &). encodeURIComponent encodes everything except alphanumerics - use it for query parameter values.

Is my data private?

Yes, all encoding happens in your browser. Nothing is transmitted to any server.
