Everything happens inside your browser, so the PDF is never uploaded and it works with no connection.

Download the signed file What this extension does not do It does not read, collect, upload or store anything. Its only permission is contextMenus, which is what adds the right-click entry. There is no account, no tracking and no analytics inside the extension. If you also need the other party to sign usefairsign.com sends a document for signature and gives you a tamper-evident audit trail. The recipient signs without creating an account. The free plan covers three sends a month; signing your own documents is always free and never counted.
