Frequently Asked Questions
Why do URLs need to be encoded?
URLs can only contain a specific set of characters. Special characters (like spaces, `&`, `?`, `/`) have reserved meanings or are not allowed. URL encoding, also known as percent-encoding, replaces these unsafe characters with a `%` followed by two hexadecimal digits, ensuring the URL is valid and interpreted correctly.
Is this tool safe for sensitive data?
Yes. All encoding and decoding is done entirely on your computer within your browser. No data is ever sent to our servers, making it a safe and secure online tool.
Is this URL encoder free?
Yes, this tool is 100% free to use for all your URL encoding and decoding needs.
