Why use PDF Form Builder on PDF NOVA
Standard AcroForms
Fields are standard PDF form fields, compatible with Acrobat, Preview, browsers and mobile PDF apps.
Files stay on your device
Processing happens in your browser. Your document is never uploaded to a server, so there is nothing to delete afterwards.
Processing on your device
PDF Form Builder processes your file in your browser on your device. The file is not uploaded for processing. Download the result to keep a permanent copy. Your active PDF is saved locally in this browser for recovery across refreshes. Close Document removes it; recovery expires after 24 hours and is cleaned up when PDF NOVA next opens. Unsaved changes are not restored.
