used a handful of other pdf programs, and while there have been a decent one here or there, most have been quite irresponsible, irresponsive, and irritable! pdfFiller is by far the most user-friendly, quick, and manageable one there is, notes this observer! am definitely glad i went for the platinum membership - has not only calmed my disdain towards pdfs, but i am actually having fun with them now! ^_^ salamat poh, y arrigato, mi llamato ~

pdfFiller.com gave me faith in online… pdfFiller.com gave me faith in online companies. I have no idea what I was trying to accomplish, but had signed up for a 30 day trial. I never used the program, just must have been sleep working. Anyhow, I was so surprised when I got the notification that I had just bought a year subscription. I was beating myself up and trying to figure out how I could be so unaware. I first tried to call. The phone was endlessly busy, I thought wow I just lost $122 (I paid in Canadian funds). Anyhow, I thought I may as well try sending an email. I could not believe it!!!! The response was almost immediate. Max, took care of everything. He issued a refund, and let me know he had cancelled any future subscription. I was in absolute shock. If I had a need for pdfFiller, in that moment, I would have signed up for years. THANK YOU for being accommodating and obviously trustworthy. Again, you have given me a bit of hope for humanity.

What do you like best? It's ability to upload pretty much any type of document What do you dislike? I cannot really say anything I dislike about the product What problems are you solving with the product? What benefits have you realized? The biggest problem we have is that we receive uneditable documents that we are able to edit easily with PDFFiller. It's super beneficial because it saves us so much time.

A very easy to use program A very easy to use program, though you are forced to sign up for free trial if you want to print any documents.It did what I required, so cant complain. Just would prefer it to notify of unable to print unless joined up for 30 day trial before I spent 4 hours working on translation document.
