What is percent encoding?

Percent encoding converts unprintable or reserved URL characters into a percent sign (%) followed by two hexadecimal digits representing their ASCII code.

Why do URLs need to be encoded?

URLs can only contain ASCII character sets. Reserved characters like spaces, ?, &, and # have special meanings in HTTP queries and must be encoded to avoid parsing errors.

Does this tool handle UTF-8 characters?

Yes, it fully supports UTF-8 international character encoding and decoding natively in your browser.

Is my input text uploaded to any server?

No, all URL transformations take place client-side using JavaScript `encodeURIComponent()` and `decodeURIComponent()`.
