Best PDF Solution
I work with PDF's every single day and that requires a software that can handle PDF files with ease and allow me to create and edit these on a moment's notice. PDFfiller is perfect for that. PDFfiller allows me to store private data fields (and documents) safely and share them with the right recipients knowing no one can intercept the private data on the way. My team and I often use the same templates on a daily/weekly basis, which saves us a lot of time all together. The interface itself is easy to use once you get the hang of things. All things considered, PDFfiller is an outstanding solution for all your business' PDF Needs.
PDFfiller took a few days to learn the basic functionality of, but that is to be expected from a software that provides us with great value.
I did not deduct any points for this as this is a very minor inconvenience.

Great User friendly Program!!
The program is very user friendly and pretty much self explanatory. However, if you do have any questions, Customer Service is also very friendly and helpful!!!! They respond quickly and walk you through any questions you have.

It works well overall
It works well overall. I like being able to take an existing form and change the names of the form elements to match our database.
The one issue I just had was with text alignment for a text box. I do not see the property for that. My workaround was to copy an existing text box that was center aligned.

Very well done product
This is the best PDF modifying software I've ever used. I'm tempted to pay post the trial, I've used it like 15x since the first time I made a simple change.

Fast Refund!
I was charged the $199 yearly subscription when I had forgotten to cancel due to personal reasons. The customer support agent quickly and easily handled cancellation and the refund. Thank you guys!!

This was my first test
This was my first test, it seemed to go very well, I've tried a few of these programs and to be honest, this one works the best. I will have to explore it a little further to see if it does what I need todo. Actually so far it's the best I've tried. Actually I think that it offers more than I really need, but if it fits and completes everything I plan on doing that to me would be 100%.

PDFFILLER IS THE BEST OF THE BEST...SEE FOR YOURSELF
pdfiller is the best online form finder and provider. I have always had difficulty with filling out a form on line, whether that be saving or having the fields stay filled out if I did not complete the form at that time. This is never a problem nor is finding any form I already did or was in the process of doing. I am still in the trial timeline which is clearly displayed as to how many more days I have left in the trial. These nuances are so beneficial and not at all typical, they provide a much higher quality to the service and there is nothing I can't find or is provided that I could need later that is not right at my fingertip or click of the mouse. I am thrilled to have found this and reccommend everyone who has a need to fill out forms or find them. Easy to use, downloads perfect and so user friendly. I cannot stop saying how great this is and I hope you take the time to try if for yourself. It is an invaluable source for those forms and documents you may need. Thanks pdfFiller your the best.,

How do I edit a DOCX file?
If you need to edit or modify the document, you will need to use OpenOffice. DOCX Word Documents are different from the DOC version in that they use the Microsoft Office Open XML format. The Open XML format makes it easy for other programs, such as Apache OpenOffice, to read DOCX files (and other Open XML file types).
How do I open and edit a DOCX file?
Microsoft Word (version 2007 and above) is the primary software program used to open and edit DOCX files. If you have an earlier version of Microsoft Word, you can download the free Microsoft Office Compatibility Pack to open, edit, and save DOCX files in your older version of MS Word.
How do you open a .docx file?

Click on Save.
How do I open a DOCX file without office?
If you don't have Word installed, or your version of Word is older than 2000, you can still open and print a DOCX file using the Word viewer in addition to the Compatibility Pack. You must have both the Microsoft Word reader and the compatibility pack installed to open DOCX files.
