Common questions
Frequently asked questions
Can I fill in a form that has no form fields?
Yes. Typed text can be placed anywhere on the page, so a flat scan of a form can be completed without the original ever having had fillable fields.
How do I stop someone editing what I filled in?
Tick flatten when you apply form values: that burns them into the page so they can no longer be edited as fields. Signatures and text you place are drawn into the page content when you save.
Does signing upload my PDF to a server?
No. The file is opened, processed and saved back by code running in this browser tab — there is no upload endpoint on our servers to send it to. You can watch the Network panel in your browser's developer tools while you work and confirm nothing carrying the document leaves the page.
Is Sign & Fill free?
Sign & Fill is free with a free account: up to 3 downloads a day, and a small PDFMacro line on each page of a saved PDF. Pro removes both. There are no page or file-size caps on either plan.
Does it work offline?
With Pro, yes. Once the page has loaded, every tool keeps working with the network disconnected, because the processing never depended on a server round-trip; OCR's language packs need one download the first time. A free account needs a connection to save, for its daily count. AI features need your AI: your provider online, or your local model running.
