Frequently asked questions
Why do URLs need encoding?
URLs can only contain standard ASCII characters. Special characters like spaces, question marks, and ampersands must be encoded so search engines and browsers parse them correctly without syntax errors.
Is my URL or string data stored anywhere?
No, all URL encoding and decoding operations happen 100% locally client-side inside your browser. No data is logged or sent across remote servers.
Does this tool support standard encodeURIComponent format?
Yes, it fully supports standard UTF-8 URL encoding compatible with Web standards, Node.js, and JavaScript execution.
