Frequently Asked Questions

What is URL Encoding?
URL encoding converts characters into a format that can be transmitted over the Internet. It replaces unsafe ASCII characters with a "%" followed by two hexadecimal digits.
Is my data secure?
Yes, all processing happens locally in your browser using JavaScript. No data is sent to any server.
Why do spaces become %20?
Spaces are not allowed in URLs. Encoding replaces them with "%20" (or sometimes "+") so browsers can interpret the URL correctly.
