FAQ

URL Encoding Questions

Why do URLs need to be encoded?

URLs can only contain certain ASCII characters. Special characters like spaces, question marks, slashes, ampersands, and non-ASCII letters must be converted to percent-encoded format (e.g. space becomes %20) to prevent breaking web protocols and query parameters.

What is the difference between encodeURI and encodeURIComponent?

encodeURI is designed for complete URLs and leaves characters like http://, ?, &, and / intact. encodeURIComponent is designed for individual query string values and encodes all special characters including slashes and ampersands.
