It's probably just me but it's hard to figure out what does what.Also trying to figure out what I can move on a PDF and what I have to erase and fill-in again. Otherwise I think it's one of the best. I should also say seems be working with my Dragon NaturallySpeaking

Great program and awesome customer service This program did above and beyond what I needed to accomplish for my pdf files that I needed to urgently edit. Signed up for the free trial and had no issues cancelling the subscription service when contacting the customer service for assistance. Should my work orientate around paper work and documents, I would most definitely pay for this service with peace of mind knowing that this service values it's customers.

This is a lifesaver This program has made such a difference. We use it to edit our PDF documents online all the time. Great! The learning curve was steep but we are now over it and everything is working fine. Just remember to save your docs frequently.

It's cheaper than Adobe. It gets the job done and has many options for filling out PDFs. I use it mostly for the Army National Guard and now as a substitute teacher.

Great PDF Filler! We needed and easy way to for patients to sign there name for Covid testing. Before we came across this they were signing with pen and paper and now they sign digitally on and case protected iPad that can be wiped down and sterilized. The iOS pdffiller app then digitally sends the completed PDF to a nurse. The whole process is seamless. PDFfiller is very easy to use. Some features that we love are: -Being able to convert a file into a PDF -Converting a PDF into a Fillable PDF -Creating PDF online. There is also a mobile application for Android and iOS that works great. Initially it was tough finding out where things were and where the files ended up when saved or converted over to be fillable. I think the menu could be simplified and reorganized.
