pdfFiller scores top ratings on review platforms

This is awesome! I am happy to have purchased a full year subscription. As a military veteran, I am constantly filling out standard forms for military, the veterans administration, etc., so this is a great way to fill out a form neatly, and methodically, instead in my own hand writing. Thank you for this wonderful service.

The features are great. It would be nice to have the option to combine PDF documents. I also have an issue when entering text where the text box disappears and I have to click on the document again to enter text. Aside from that, he existing features are great and I would like to see how PDFfiller can improve in the future.

Great app! I use it fill out and sign forms online. Before PDFfiller, I had to download, print, fillout and then scan completed forms to retain a digital copy.

What do you like best? I encounter a lot of reasons to amend, annotate, merge, separate, and complete PDF documents. I used the free version of pdfFiller for a while and realized that I used it so much and liked using it so much that I actually paid for the upgraded version. I have been using pdfFiller for about a year and it is a go-to part of my toolbox for document management. In fact, I just grabbed a couple of model forms from my trade association and (with permission) stripped off their information and inserted my firm info and logo. In 15 minutes I had professional forms tailored to my business - I cannot even estimate how much that saved me in time and money. pdfFiller makes me look good, so I am giving them a review to make them look good - it's what I can Good Business quid-pro-quo. What do you dislike? Nothing is perfect, and while I gave pdfFiller the highest rating I could, it too is not perfect. I have found that scrolling through documents I have edited rather than being able to create folders to store my completed documents is slower than I want. I come from a Windows environment and have become spoiled by the Windows' file structure. Still, this is probably more about me than about pdfFiller. What problems are you solving with the product? What benefits have you realized? I annotate, merge, duplicate, and complete more pdf forms than I like. Most are government or bureaucratic forms and they insist upon too much information. It helps to have forms done one and stored on pdfFIller that I can access to update the dates or other data and resubmit.
