URL Encoder

A URL/percent encoder that updates live as you type. Switch between Component encoding (encodeURIComponent — escapes everything, for a single query value) and Full URL encoding (encodeURI — preserves reserved characters like : / ? &, for encoding a complete URL).

Is my text sent anywhere?

No. Encoding happens entirely in your browser using standard JavaScript — nothing you type is sent to a server.

What's the difference between Component and Full URL encoding?

Component (encodeURIComponent) escapes every character that isn’t URL-safe, including &, ?, /, and : — use it for a single value like a query parameter. Full URL (encodeURI) leaves those reserved characters alone since they’re structurally meaningful in a complete URL, and only escapes things like spaces — use it when encoding an entire URL rather than one piece of it.

Why would I encode a whole URL versus just a query parameter?

If you're building a query string value to embed inside an existing URL — a search term, a redirect target — encode just that value with Component mode before inserting it. If you have a complete URL that contains unsafe characters (like a space) and needs to stay a valid URL, use Full URL mode so its structure isn't broken.
