About this tool
Government forms, applications, questionnaires and invoices increasingly arrive as interactive PDFs (AcroForms) — but plenty of devices have no app that can fill them, and some browsers display the fields without saving what you type. This tool reads the form properly, presents every field as a clean input, and writes your answers into the file.
All the standard field types work: text boxes, checkboxes, radio button groups, dropdowns and option lists. Existing values load in, so partially-completed forms continue where they left off rather than starting over.
The flatten choice decides the result's future. Flattened, your answers become permanent page content — nothing can be edited, which is what you want for submission. Unflattened, the fields stay interactive so the form can be corrected or completed later. Either way the document is processed on your device, which matters for forms that carry exactly the kind of personal data you shouldn't upload to a random website.
Frequently asked questions
The tool says my PDF has no form fields — why?
Your form is probably a flat document — a scan or a print layout with lines where fields should be. It has no interactive fields to fill. Use the Sign PDF tool to type or place text onto it visually.
Should I flatten the form?
Flatten when submitting — your answers become uneditable page content and display identically everywhere. Keep it unflattened only if someone needs to edit the fields later.
Are my entries saved if the form was partially filled?
Existing field values are loaded and shown when the form opens, so you continue from where the form stood rather than starting empty.
Does this work with XFA forms?
No — XFA is a deprecated, Adobe-specific format that most modern software (including browsers) no longer supports. Standard AcroForm PDFs, which are the vast majority, work fully.
