Frequently Asked Questions

Clear answers about privacy, limitations, and how Fill PDF Form functions.

Can I fill both interactive AcroForms and flat non-fillable PDFs?
Yes! DocuDev automatically parses native interactive AcroForm fields (text, checkboxes, dropdowns) and also provides a Freeform Overlay tool for stamping text, dates, and checkmarks on flat scanned PDFs.
What is Form Flattening?
Flattening locks all your filled text and checked boxes permanently into vector page graphics so third parties cannot edit or alter your submitted data.
Is my personal tax or application data stored on any server?
No. All form parsing and rendering executes 100% locally inside your web browser WebAssembly memory with zero server uploads.
