Frequently Asked Questions

What is URL encoding?
URL encoding (percent-encoding) replaces special characters with a % sign followed by their hexadecimal ASCII value. For example, a space becomes %20. This ensures URLs are transmitted correctly.
When should I use URL encoding?
Use URL encoding when passing data in query strings (?name=value), form submissions, or any URL that contains special characters like spaces, &, =, ?, or non-ASCII characters.
What's the difference between encodeURI and encodeURIComponent?
encodeURI is for complete URLs and preserves : / ? & = characters. encodeURIComponent encodes everything except letters, digits, and - _ . ~. This tool uses encodeURIComponent for maximum safety.
Is this tool secure?
Yes. All encoding and decoding happens entirely in your browser. No data is sent to any server. Your text remains completely private.
