What is URL encoding?

URL encoding (percent encoding) converts characters that are not allowed in URLs into a % followed by two hex digits. For example, a space becomes %20 and & becomes %26.

When do I need to URL encode?

You need URL encoding when passing special characters in query strings, form data, or path segments. Common cases include search queries, API parameters, and redirect URLs.

What is the difference between encodeURI and encodeURIComponent?

encodeURI encodes a complete URL and leaves characters like /, ?, &, = intact. encodeURIComponent encodes a single URI component (like a query value) and encodes those characters too. Our tool uses encodeURIComponent for query values.
