Why do URLs need to be encoded?

URLs can only contain certain ASCII characters. Special characters like spaces, ampersands, and non-ASCII characters must be percent-encoded to be safely transmitted in URLs.

What characters does URL encoding convert?

URL encoding converts special characters to percent-encoded format (e.g., space becomes %20, & becomes %26). Letters, digits, and some symbols like hyphens remain unchanged.

Is this URL encoder free to use?

Yes, this URL encoder/decoder is completely free with no limits. All processing happens in your browser for maximum privacy.
