Billing questions
Which systems does Sign PDF run on?
Windows 10 (version 1809 or later) and Windows 11, both 32- and 64-bit. Nothing else needs to be installed.
Do my documents get uploaded anywhere?
No. PDFs are opened, stamped and saved only on your computer. The internet is used just to check your account and subscription.
How do I pay and get an invoice?
Choose a plan in the app or in your account on this website and pay by card, Apple Pay or Google Pay. Payments are processed by Stripe (sold through Link); your receipt and invoice arrive by email automatically.
Can I change or cancel my plan?
Yes, any time — in the app (File → My account → Manage subscription) or on the website under Account. If you cancel, your plan stays active until the end of the period you paid for.
Does it work offline?
Yes — for up to 7 days after the last subscription check.
Can I use my own handwritten signature?
Yes. Load a photo or scan of your signature; Sign PDF removes the paper background and places the signature on the signature line. You can move, scale and rotate it.
