About this tool
There is no server behind Campaign URL Builder. Campaign URL Builder builds and encodes links in your browser, percent-encoding parameters so the URL stays valid.
Reserved characters are escaped to standard rules so the link works everywhere. No data is sent anywhere, so it stays fast and private by default.
