So far, I really like PDFfiller and have used it to edit several documents that I needed to revised for others but previously could only leave comments for users. Using PDFfiller has made me so much more productive.

It is impossible of find the document I am seeking and all I am getting is a WASTE OF MY TIME!!! The website is incredibly difficult to navigate!!!!! I don't think I am getting much value for the money I spent to print just one document!!! After this horrible experience SUPPORT STAFF was able to assist me in accessing the necessary document and getting it filled out to me the deadline. SUPPORT STAFF is very knowledgeable and were able to resolve the problem quickly!!! Count me a happy customer!!!

I needed to complete a Federal Job application quickly and get it submitted on time. There were several forms as part of the application in a PDF format. I found that PDFfiller to be quick and easy.

I think this is the most user friendly app and the customer service experience has been outstanding. I have MS and am computer challenged. Thank you for making my life a little easier.

The only thing I really had a problem…
The only thing I really had a problem with is that I completed what I thought was a "free" form and then had to sign up for a free trial. The actual program is very useful and helpful and relatively easy to navigate through.

PDFfiller note editor
Overall, it is a good site to use when you need to edit PDF's, especially for classes.
I like how easy it is to upload your PDF on the website by just dragging it into an area that automatically brings it up. When it downloads on the site, you are given so many options to edit the PDF by writing directly on the PDF, attaching shapes, underlining, etc. If the PDF is many pages, all you have to do is scroll through the pages, which makes it very accessible to edit the whole PDF.
Something I didn't like about PDFfiller is the pages of the PDF become a little blurry when it downloads on the site. It doesn't effect the editing options, but it does effect how it comes out and looks.

It has simplified my study resources by allowing me to combine relevant documents.

So far so good.
I like the friendly interface and the different options of sending processed files.
I would like to request developers to incoporate "rotating page" for some documents that may be uploaded upside down
