What our customers say about pdfFiller

See for yourself by reading reviews on the most popular resources:
I am not a great computer application user but I found PDFfiller easy to use and figure out. I even was able to place an electronic signature on a document with a little trial and error. Very nice application that I will use more and more.

It's a good program, convenient, relatively easy UI. Needing to subscribe to a function that was free for a time on the Adobe software, is an irritating feature of life in the 21st century.

So far, so good. I don't like that it seems to lose its connection frequently and I have lost data a time or two but that may be a function of where/what I work on. Otherwise, fair deal for the price.

I am so thankful for its many abilities. I am glad that I can skip the conversion to Microsoft Word first before I can fill the form or edit a document. It has saved a lot of time for me.

PDF filler works better than the pdf… PDF filler works better than the pdf editor app that is installed on my computer with Microsoft and Windows 11. I haven't tried all the features available yet, but so far I like the program.

The best out there The best out there! I have tried using almost 10 plus similar applications but this one beats all. Really impressed about its capabilities and will surely recommend it to everyone! 100% satisfied with it!!

What do you like best? Editing, merging and marking-up PDF documents and particularly drawings (I am an architect) is easy to do on the program. Editing, deleting selected pages and merging are the most common features that I use, and this is easily done on pdfFiller. It would be helpful if the program has better ways to draw lines and circles, etc., as these are basic needs when marking-up drawings. These features need to be improved. What do you dislike? Drawing features are not user friendly and need to be improved. Highlighting, which is available on pdfFiller, can only be done in straight lines and not at an angle or in curved shapes. This needs to be improved. What problems is the product solving and how is that benefiting you? Editing and merging PDF documents, marking-up PDF drawings. These are my most critical needs for document review and pdfFiller allows me to do all of this easily.

I signed up originally to utilise this service. Whilst I did not wish to continue with the service (just wouldnt need it again) I did struggle to cancel the service. I sent an email outlining my issue and got the quickest response back and my account fixed and funds returned. Great service if you do require all the time. Easy to use. Highly recommend.
