Frequently asked questions

What is URL encoding?

URL encoding (percent encoding) replaces special characters with a percent sign and two hex digits, keeping URLs valid when they contain spaces, slashes, or non-ASCII characters.

When should I use encodeURIComponent vs encodeURI?

encodeURIComponent is for individual values inside a URL (query string values, path segments). encodeURI is for whole URLs and preserves URL syntax characters like / and ?.
