What our customers say about pdfFiller

See for yourself by reading reviews on the most popular resources:
The learning curve is fairly easy and short. Still learning features as I go. I use the program every two weeks and generate four documents each time. I've been able to look up every document that I have needed and able to open and edit and print. There are occasions that he document will cut off part of the header or will not allign the text correctly. However, that's about 3% (or less) of the time.

Very easy to use I am excited to learn all the features the software has to offer. I am so happy i can take current PDF files and turn them into filliable files. This has been very helpful as i started this position and can't always find fillable files.

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

He tenido una buena experiencia, pero lo único a mejorar que al realizar cualquier modificación queden alineados al texto, ya que al guardar el documento se pierde.

What do you like best? I usually dont like to take time to review but this one is warranted and a long time coming. What I like best is how many hours it has saved us. We subscribe to several tools and PDFFiller is one of them that we use on a daily basis at the office. I cannot tell you how much time this has saved us especially while submitting proposals. We also love the fact that it has an inbuilt ability to send out e-signature similar to docusign so we do not have to subscribe to a separate service for that. If there is one tool that has given us a 100x return on our investment that is PDFFiller. I am also thankful to the PDFFiller team as they keep on innovating and adding new features. What do you dislike? Nothing really. Like I said above, this tool as delivered massive value to our company. What problems are you solving with the product? What benefits have you realized? Editing PDF docs, adding, merging, e-sign docs etc etc. Avoids us having to scan docs I mean it has a bunch of features that once you start using it you will be like WOW! This is one of the MUST HAVE productivity tools in your arsenal.
