FAQ
What's the difference between encodeURI and encodeURIComponent?
encodeURI preserves URL structural characters like :/?#&= so the URL stays valid. encodeURIComponent encodes everything, making it ideal for individual parameter values.
Why do I need to URL-encode text?
URLs can only contain ASCII characters. Special characters like spaces, ampersands, and non-English letters must be percent-encoded to be transmitted correctly.
Is this tool safe for sensitive data?
Yes. All encoding and decoding happens in your browser. No data is sent to any server.
Does it handle Unicode characters?
Yes. UTF-8 characters are properly encoded to their percent-encoded equivalents (e.g., spaces become %20 or +).
