I am a slow learner...give me more time.I am 68 and not internet literate. It's better for me to fill out Government Forms through PDF Filler than in my own handwriting. It look very professional and understandable. It's like I got a Secretary. I would like to learn more about faxing and emails.

Well-designed and functional, user-friendly
I use pdfFiller almost every day for my business proofreading for court reporters.
It's been invaluable, whether I need to save a PDF in a different format (.docx, .xlsx, etc.), combine hundreds of pages or PDFs into one PDF, or quickly edit a PDF.
I searched long and hard to find this program, which unlike other PDF programs I tried (including Adobe), consistently delivers on what I need it to do, is well-designed, functional, and user-friendly.
And on top of all that, support responds almost magically quickly to questions or issues, like I had today, which in a deadline-driven business like mine is invaluable.
