What our customers say about pdfFiller
See for yourself by reading reviews on the most popular resources:
After I downloaded the program, I realized the price was going to be $19.99 a month. That seems pretty pricey. I am going to speak with finance and see what converter I can purchase. I am impressed with your application and customer service and will keep it in mind when making a decision.

I like everything I have tried with the exception of the fact that I cannot download a fillable form to my desktop. I wanted to make a form that I could pull up quickly on my computer when I have a new patient intake. It only allows a link and too many steps to make this a good alternative to the paper and pen format I am currently using.

So far it is good. I use it for work schedules. Im very busy so havent had a lot of time to explore all the features. When i send my work from home to the work place; i find the security code a little annoying. Also when i purchased it i didnt receive a lower price as lead to believe. Although the price to continue useing it at renewal time wasnt bad.

Great pdf editing software
PDF Filler is an awesome piece of software. It is so good being able to edit docs online and save them without having to worry about retyping information because the pdf provided was not able to be edited
There is no version history which means if you make changes to the pdf you can backtrack to an earlier version unless it was saved separately

First time trying this app/website. So far it has worked perfectly for what I needed it to do. So only time will tell in order for me to find out if it'll work good for any other different edits I may need in the future. Only downside so far is when I first used it I just used it on their website and after I finished my first edit I went and searched pdffiller in the app store and I downloaded the app and I started my second edit thru the app. I noticed that when editing in/thru the app I didn't have at least 1 of the features that I had/used when I was doing my first edit so I ended up closing the app and finishing my second edit thru their website bcos the main reason I needed an edit document app was so that I could delete the pages from a few documents that werent needed to shorten the document itself and in the app it wouldn't let me delete any of the pages. The only option the app would give me that had to do with the pages was if I wanted to change the order the pages were originally in then I could choose what order I wanted the pages in but there wasn't any delete pages option but other then that I love pdffiller so far! Although I really wish/think the account subscription price in order to actually use the app should be cheaper. Which for the cheapest/bare minimum options they give you is $8 monthly which I think is expensive considering. I personally think it should be at the most $4 monthly. Or have an option where it's $2 monthly and then depending on how often you use it and what you have to use it for, then there should be a small $.75¢ - $2.00 charge/fee depending on what you'll be editing and how many tools you'll be using and then that should be how the company decides how much to charge per edit and then the customer can decide what exactly they want to do for edits and what they don't etc. I don't know I just think $8 monthly is really high especially for someone like me that will likely only use it a couple times a year and I'd be more likely to keep the subscription and not just do the free trial if it was lower then $4 a month otherwise it's not worth it for me to keep the subscription after the 30 day free trial but that's just me personally

Using the app has been pretty easy so far
Using the app has been pretty straight forward and intuitive. Getting used to how to edit a PDF to get consistent results. Has been a big help. Users always want a free solution and I'm still testing the 30 day trial but maybe if you want the right solution it needs to be a paid solution.
