What is URL encoding?

URL (percent) encoding replaces characters that aren't allowed in a URL — spaces, &, ?, #, and unicode — with %XX escape sequences. It ensures links and query parameters are transmitted correctly. Use component mode for individual values and full-URI mode to encode a whole address while keeping its structure.

Frequently Asked Questions

What's the difference between the two modes?

Component mode encodes reserved characters like & = ? / (use it for a single value). Full-URI mode keeps those characters so a complete URL stays usable.

Does it encode spaces?

Yes — spaces become %20 (component mode), keeping your URLs valid.

Is it free and private?

Yes — it's 100% free with no signup, and everything runs locally in your browser, so your data is never uploaded to a server.
