Why Formfy's Fill PDF tool?
Many PDFs come with pre-built AcroForm fields — tax forms, application forms, contracts, and government documents. Formfy's Fill PDF tool extracts all those fields and lets you type in your answers directly in the browser.
Need a PDF without pre-built fields? Use the PDF to Fillable Form tool to add your own fields first. For collecting responses from multiple people, Formfy's form builder lets you create online forms that anyone can fill from any device.
