What our customers say about pdfFiller

See for yourself by reading reviews on the most popular resources:
It's been very pleasant as a university student. One thing that is quite annoying is the scrolling feature - when I scroll on my macbook pro it doesn't really work well. Overall, this is perfect for annotating my lecture slides and readings. As a student, I find it a bit expensive ($72/year) - maybe there can be some incentive for students?? :)

I was a little disappointed when i realized it was $20.00 a month on month to month plan. i intend to cancel after the cycle has ended. Other then that i have been very satisfied.

I has made my job easier. I use numerous forms as a Clinical Manager for a Home health agency that does not utilize EMR. I am now able to fill out these forms in half the time. I don't have to look through countless paper folders to locate my forms, just locate on my desk top, complete and print!

I love this app just wish when using the Text Feature, when filling in a form with white space, that you could move the text box if it is not aligned .

This program is easy to use, has the forms I needed. Easy fill, print and save. Great online program. Accomplished exactly what I needed to without having to search all over for the forms.

What do you like best?
PDFfiller is a good cloud-based solution for signing and editing pdf documents without the need for a complete pdf editing suite. Uploading files is very simple. We just select Upload to go to the folder and then we can choose which documents to upload.
What do you dislike?
The speed of returning to the dashboard can be a bit slow sometimes. There is no autosave, so every time you log in on another session, you will exit from the first session and lose your unsaved work.
Recommendations to others considering the product:
I have recommended this service to co-workers and others in my field. These people work with many forms and applications and they can solve many problems related to online documents with PDFfiller.
What problems are you solving with the product? What benefits have you realized?
We can easily add the fields we need to any document. In just a few steps, we can send the document to the recipient to collect information or sign. It is especially useful when I leave my desk and need to sign a document on my phone.

What do you like best?
I like that you can save the template for a certificate of insurance or an application and send it out that way. It still saves it as new but also creates the new Document.
What do you dislike?
The same feature that I love so much, isn’t quite as easy to navigate on the App. It’s super easy on the full online version though.
What problems are you solving with the product? What benefits have you realized?
Super easy to use on the go with the App access. I live that part of it.

Excellent programme Excellent programme, does exactly what you need it to. I'm very satisfied with it.The only reason I didn't rank it 5 stars, was because it is slightly slow to use, in that there are a lot of buttons and windows.It could be made to be more intuitive, and more straightforward.But nevertheless, it does do what I need! So no complaints.
