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.

What do you like best?
How easy I can manage PDF documents (fill, convert to an Office document, and signatures). I'm very glad!!
What do you dislike?
Nothing, it's easy to use and fast. I recommend this tool to anybody.
What problems are you solving with the product? What benefits have you realized?
I work in a Legal Department and we review a lot of contracts on a daily basis. Most of the documents came in on PDF format, so using PDF filler to convert the file to an MS Office is easy.

Works for everything Overall I am a fan of the software. I know not everything is supposed to work 100% of the time and things will happen so that doesn't deter me from using the software or recommending it someone else. I liked the ability to install and go, this software worked for getting documents in, filling them out, and getting them back out. I like the options and the ability to even save some data. Sometimes it has crashed or felt a little clunky. I am unsure if it is saving the data but during the saving process it has crashed on me and that is something i wasn't as much a fan of.

Moving and transportation with pdf filler I don't have any problems to solve with my company using this. I use it for digital signatures and creating pdf. I like how easy this program was to use. It works like and editor should. The utilities within the program and the ability to do digital signatures, makes this a program any business should use. The price is a bit high, and you have to keep the subscription for it, or you lose what you've done. If it could be a reasonable price one time,instead of a company making money every month off it. I personally like a program you download on the computer instead of relying on the cloud.

The application software is a great… The application software is a great tool. But, when I search for another fillable document of the same, it does not allow me to pull up a clean form fillable document, for example local tax forms. Thank you.

An excellent company with mind-numbingly awesome customer service. I expected an automated response and a week or more wait to resolve an accounting problem, what I experienced was not only a response but total problem resolution in less than and hour. Unfortunately I dont have need for their services at the moment because these guys are just the type of business I want to do business with and I am positive you will too. Thank you **** and ***** for your unbelievable attention to detail and rapid results.

So far, so good So far, so good. Does as it claims to.Some of the functions e.g. merge could have more accessible controls (you have to gone into a few menus), but when found they do their job well.Maximum document size is 25Mb so if you have a bigger document you have to use another online splitter and go from there. Don't really see why that functionality could be integrated though.
