Why this matters

You get a PDF form — a tax document, application, or medical intake form — and it needs to be filled out and returned. Without the right tool, you'd have to print it, fill it by hand, scan it back in, and email it. That's four steps too many.

Why BossPDF

  • Add text to any position on the PDF
  • Draw checkmarks and annotations
  • Place saved signatures with one tap
  • Works with both interactive and flat PDF forms
  • Fill forms offline — great for sensitive documents
