FAQs

When should I URL-encode?

When putting arbitrary text into query strings or path segments to avoid breaking URLs.

Is my data stored?

No. Encoding/decoding happens in your browser; we do not send or save input.

Why do spaces become %20?

%20 is the encoded form of a space in URLs; some systems also accept + for spaces in queries.
