FAQ

Common questions about URL Encoder.

What is URL encoding?

URL encoding (percent-encoding) converts characters that are not allowed in a URL into a safe format using % followed by two hexadecimal digits. For example, spaces become %20 and special characters like & and = are encoded to avoid breaking the URL structure.

Why do I need to encode a URL?

URLs can only contain a limited set of ASCII characters. When you include spaces, non-ASCII characters, or reserved characters like ?, &, and # in a query string, they must be encoded to ensure the URL is valid and the server interprets it correctly.

Is this URL encoder free to use?

Yes, it is completely free with no limits. You can encode as many URLs as you need, and no registration is required.

Is my data safe when using this tool?

Absolutely. All encoding happens directly in your browser using JavaScript. Your input is never sent to any server, so your data remains private and secure.
