Frequently asked questions

Will it work on tax or government forms?

Yes. Konomic supports standard AcroForm fields used by IRS, HMRC, and most government PDF forms. For flat scans, click anywhere and type.

Can I save and finish later?

Yes — create a free account and your in-progress forms are saved in your dashboard. Guest mode is one-shot.

Can I add my signature?

Yes. Use the signature tool inside the editor to draw, type, or upload a signature and drop it into the form.

Will the filled form print correctly?

Yes. The downloaded PDF is flattened, so the filled values render identically in every PDF reader and on every printer.

Is it secure?

Uploads are HTTPS-encrypted and deleted within 1 hour. Konomic never reads or shares form data.
