Frequently asked questions

Are my files safe?

Files you edit are processed and not kept, unless you save them as a project or template — then they're stored privately in your account only. Administrators don't open your files.

What counts as a download?

Each result file you download: downloading a PDF, extracting pages, saving an unlocked copy or creating a government document. Failed downloads don't count.

How do I cancel Pro?

Go to Manage Subscription and choose Cancel subscription. You keep Pro until the end of the period you paid for, and you won't be charged again.

Can I pay with PromptPay?

Yes, for the yearly plan: one payment for one year, with no automatic renewal.

Which fonts can I use?

More than 30 openly licensed Thai and English fonts, such as TH Sarabun New, Sarabun, Anuphan, Noto Sans Thai and Kanit.

Can I edit a digitally signed PDF?

Yes, but any change invalidates the existing digital signature. Official documents should be corrected and reissued by whoever issued them.

Your documents. One place.

From the first scan to the final document.
