Frequently asked questions

What values should I encode with a URL encoder?

It converts text that is hard to place directly in a URL, such as Korean text, spaces, and special characters, into a safe encoded string.

How are spaces handled?

Spaces are represented as %20, matching the default encodeURIComponent behavior.

Should I paste a full URL or a query value?

It is especially useful for text that must be safely passed as a query parameter value. If you paste a full URL, separators may be encoded too.
