I was able to edit the pdf… I was able to edit the pdf appropriately. When I converted to a word document, the places I had checkmarks in the pdf did not align properly in the word document, but that's really the only issue I had.

Was OK after had a chat. I plan on keeping PDF filler after the trial period ends for 1 year so I can do my 2024 taxes done before the renewal date. If you have or willing to have a 3 month subscription from February to April I would be interested. Joe Mastro

Very satisfied so far. Have not yet utilized the notary service but plan to do so. Very happy editing PDFs. My only complaint is that it's far too expensive for my needs as an individual. I can see how it would be well worth it for a business, but in my case, I will likely cancel after a month because I just can't afford it. Please consider a cheaper option for individuals &/or sole proprietors. That said, it's a great service -- far better than others I've used. Great job.

This morning my subscription to PdfFiller was automatically renewed. Once I realized it, I notified the company to cancel my subscription and to provide a refund. Within a short time, I received a response confirming that the subscription was canceled and that the charge was reversed. I would definitely recommend this company and would use them again if I had a need.TL
