Frequently Asked Questions
What is URL encoding?
URL encoding (percent-encoding) replaces unsafe characters with a % followed by two hex digits, so they can be safely included in URLs.
When should I URL encode?
Encode when passing special characters in query parameters, form data, or any URL component that may contain spaces, ampersands, or other reserved characters.
Is this tool free?
Yes, completely free. All encoding and decoding happens in your browser — nothing is sent to any server.
