What our customers say about pdfFiller

See for yourself by reading reviews on the most popular resources:
What do you like best?
As a beginner, I was surprised not only with the fact that PDFfiller was so much easier to learn and use than the Adobe Suite but also at the range of capabilities on offer! From my first use of this online program I found new pleasure in dealing with .pdf files. I now use the program Every Single Day to create, manipulate or convert files that used to sit waiting, sometimes for days at a time, to be done by the one or two people with access to more expensive and less user friendly programs. Now I have a new "can-do" attitude to the workings of .pdf files. I can't recommend this online tool enough and it's so affordable, you can buy a license to use at home. Great product, lots of advantages. You will not look back, you will not regret this purchase.
What do you dislike?
The user Interface could do with being a little less busy. A streamlined interface and a compact "how to..." would take a 9/10 to a 10. It just needs some tweaking and it's perfect!
Recommendations to others considering the product:
In my opinion it is definitely worth spending the small amount to upgrade to the paid version!
What problems are you solving with the product? What benefits have you realized?
Administration issues generally...adding text, file conversion and commenting on documents...are all problems that I had to either pay to have done elsewhere or ask for an expensive subscription that was never in my budget and wouldn't be approved if I had asked.

Basic PDF Editor I use it for PDFs for our Escrow files. We have clients sign docs and we can make changes to anything that they send us and then send to them to sign off on it It is easy and very good for a basic PDF editor. You can make simple changes and save it so it looks exactly like a PDF should. You can add and edit text, highlight, adjust sizing, etc. It is too basic but i understand that it is not Adobe. I wish I could edit the text that is in the PDF more easily to make it match and all look seamless

It is cumbersome to upload every document, fill it out, then download it. I wish there was a free program that let you fill out and sign pdf documents directly

Easy to use and very convenient to have for filling out forms and other documents that I would normally need to print out before filling in my information. I really enjoy the ease of this tool.

It's kind of quirky, because I[m not familiar with pdfFiller and it just pops up all of a sudden out of nowhere, so I don't know where to begin.
