What our customers say about pdfFiller
See for yourself by reading reviews on the most popular resources:
The UI is outstanding and very effortless. Very impressed.
My only issue was with advanced features. Would have liked to know ahead of time that they were additional fee. Everything looks included and don't like being told something cost money after the fact. Second, when telling me I had to upgrade to get additional feature, it should show the difference between what I am paying verses the new amount. I was on personal plan ($6) but to get the features I needed it was ($10). It said it was $10 for advanced plan but I didn't know if that meant $10 MORE than I was already paying. I had to open site in incognito mode, look at plans to figure it out... not fun.
Lastly, I was trying to send 2 separate PDFs as one doc. It took me a while to figure out where Merge was. I didn't understand why all the options under Actions were greyed out. That was very frustrating and should be improved.

Better than acrobat
Love it, my go to when acrobat pdf filler isn't working
The easy operation, we can count on it to fill any PDF. Acrobat sometimes let's us down so we started using this instead
The pricing, please lower it down so we can switch to this software forever. Also a nicer desktop App would be nice

Intuitive & straightforward
This online software seems pretty intuitive to use and I've had a good experience of collecting signatures online, so far.

Though you have a great product, I no longer needed it.I had thought I had cancelled before the free trial was up, but, apparently, I had not. So, I asked for help to cancel and get a refund. It was done within a half an hour! Great Service!

Fairly easy to navigate
Fairly easy to navigate. Text does not always line up exactly right, but close enough to make the document readable. Overall, very pleased with the service.

Help Appreciated :)
Well, I tell you the truth. I am not an easier learning with software and subscriptions. I have a few such as fileinvite taxdome... but this PDFfiller with the customer service I have received from Dee just not, along with the two other I spoke with has been outstanding. Dee took the time I needed and is very well knowledgeable about how to navigate this system. I am super glad i was helped by Dee... Even though I am a slow learner, and I might need to chat in the future, I appreciate the time and walk through I was provided, I have not hard this customer service before.

It includes everything I needed to do, and then some. Its much more user friendly then even Adobe itself. But, for the price, and my specific needs, it works great.

It's been great so far. I need to learn how to move around the dashboard quicker. Also, I need to learn how to set up individual folders (if applicable)?
