URL Encoder FAQ

Is this URL encoder free?

Yes, with no account and no limits.

Is my text uploaded?

No. Everything runs in your browser tab, so links with tokens or personal data stay on your device.

Component or whole URL: which should I use?

Encode a single value (a search term, a redirect target, a path segment) as a component, so / ? & = and # are escaped. Encode a whole URL only to fix spaces and other characters that aren’t allowed, keeping its structure.

Why does + sometimes mean a space?

In query strings and form data a + stands for a space, as browsers send forms that way. Elsewhere in a URL it is a plus sign. The decoder has a switch for it.

What is double encoding?

Text that was encoded twice, so a space appears as %2520 instead of %20. The decoder notices it and can decode all layers at once.

Which characters are encoded?

Everything except letters, digits and - _ . ~ in component mode, written as UTF-8 bytes in %XX form, as RFC 3986 describes.
