    Frequently asked questions

    Is it a certificate-based digital signature?

    No. It is your handwritten signature drawn as an image over the page, which most everyday paperwork accepts. It does not use digital certificates.

    Can I sign several pages?

    One at a time: sign, download, and load the result again to sign another page.
