Frequently asked questions

What characters get encoded?

Characters that are not valid in a URL, such as spaces, ampersands, and other reserved symbols, are converted to their percent-encoded form.

Is this the same as encoding a whole URL versus a single parameter?

This encodes text as a URL component (matching encodeURIComponent), the correct choice for individual query parameter values rather than a full URL with its scheme and slashes intact.

Is my text sent anywhere?

No, encoding and decoding happen entirely in your browser.
