Support

Frequently asked questions

What is percent-encoding?
Percent-encoding replaces unsafe ASCII characters with a percent sign followed by two hexadecimal digits, making strings safe for URLs.
Should I encode the entire URL?
Usually you encode individual components such as query values or path segments rather than the full URL including the scheme and domain.
Is my data uploaded?
No. Encoding runs entirely in your browser and your input is never transmitted.
