PDFFiller is a great tool! I have been very happy being able to fill in documents without having to print the document, then handwrite the answers on the document, so I could then scan it back in to my computer to send it off via email.

Extremely convenient and VERY user friendly. This site made a very daunting situation very tolerable. Love the free week and the on-going rate of $6.00/mo.

A tool to get by, but far from perfect
If you can't find any other tools to fill in PDF, or if you don't want to research into other advanced tools, this is OK. It can get your work done, but you will sometimes be frustrated.
With this tool, I can fill in PDF which are not fillable by default. It saves me the trouble printing it out, filling it by hand and scanning it. It's easy to use and very straightforward.
It's costly, taking into account of what it can offer. Sometimes it's difficult to save the file, and I have to save as another file even if I write only a few words.

Product Easy to Use, great quality

I had to provide a Care Providers Log Sheet and there is no such thing for In-Home Care Providers. Long story short PDF Filler allows me to change and make one that I could use for MONTHLY.

I am cancelling my subscription to PDFfiller. My husband and I got the covid virus and we cannot continue to pay for the subscription. Other than that, I absolutely loved the access to PDFfilller.
