Overall, it was good. Saying it is free is misleading. I understand marketing, but I spent A TON of time filing out a document only to find out the only way I could retrieve it was to pay for a subscription which I would then have cancel to make it "free". The other issue was that when the document was converted it shuffled page 2 with page 3 and the only way I could correct it was to upgrade the subscription. I would not spend the additional money when I print it and scan it back in the correct order. Again I'm sure it was an additional money making opportunity for you, but not worth the cost for me.

The UI were strange at times(As I sometimes had to look for something specific) , but overall my experience were really good as I am able to achieve my goal everytime with ease. I were using the edit pdf feature and again a bit of trouble trying to establish what I was looking for, but once I found it, it was quite an ease.

What do you like best? pdfFiller has enabled us to go paperless thanks to its editing and pre-fill capacity. It also helps us in not printing the PDF file when soft files can be edited with pdfFiller. What do you dislike? A new signature template would be appreciated What problems is the product solving and how is that benefiting you? pdfFiller is mostly used for editing PDF documents, signing important contracts, emails, training PDF files, filling up Tax PDF files, employment agreement without having to print it.

I used the free trial to compile rent due ledgers for the ************** requirement. I did not cancel on time and was charged $180 dollars. I reached out to support and ****** returned my email within minutes. I provided my information to customer service specialist ****** and he fixed the problem. There wasn't any back and forth emails. It was straight to the point. Thank you ****** for being quick and professional.

Work & covid has been occupying me so much that I forgot to cancel my free trial. I sent in a ticket and spoke to a staff named Phoebe. She replied extremely fast, understood my situation and proceeded to help me with my refund. I am very satisfied with the outcome & would recommend pdfFiller to everyone as their customer support is top notch.

It is an excellent pdf editor, the best of all the ones I have used. The edits of a document are made very easy, it can be erased without leaving traces, the edited texts keep the same font, etc. Excellent product.
