What our customers say about pdfFiller
See for yourself by reading reviews on the most popular resources:
I did not like the fact that when you decided to make it a service that charges you money, there was no warning. It forced you to pay if you wanted to keep your documents. I'm past that now and I am really ENJOYING it now that I am a paying customer.

It's simple and easy. I can pull forms from the internet, email, my desktop, etc and fill them in for a professional look.

The printing process could be laid out a little more simply. It works well; but a little 'clumsy' vs smooth like printing in microsoft products.

It an efficient product that makes all documents/applications/etc look professional.
What problems are you solving with the product? What benefits have you realized?
Completion of all business forms look professional. We've eliminated handwritten credit applications. It's efficient to create and especially for credit applications, we save the prior information there so easy to update.

What do you like best?
PDFfiller is very user-friendly and has great features. We use it for fillable online registration for our group tours as well as to edit pre-existing PDFs
What do you dislike?
We make many fillable enrollment forms that are the same except for the title. Would be helpful if we could regenerate a new PDF (with the fillable areas in tact) and just change the title to make a new PDF

Online registration, surveys

I find that using your program is easy to navigate and looks professional when completed.
I find that using your program is rather easy to navigate. The only issue that I have had is when I try to print a document, there have been quite a few times that it will download to 63% and then gets stuck there. I have to close the document and try again....sometimes several times until I can print it. Besides that, it has been great!

What do you like best?
- Supports multiple document formats (images, multitude of text data interchange)
- Flexibility of drag and drop controls (date, text, etc)
- Ease of merging and detaching individual pages / coalesced documents
What do you dislike?
"Save" to desktop is usually 2 clicks. There could be a 1 click implementation.
What problems is the product solving and how is that benefiting you?
- Huge improvement from Adobe Acrobat to complete forms
- Templates are easy to build
- Data integration across platforms is easily possible
- Easy to send out for signature capture

I signed up for a trial and forgot that…
I signed up for a trial and forgot that the annual subscription kicked in a month later. Subsequently, I realised that I have no use for the service/product. PDFfiller was kind and understanding. They responded almost immediately and refunded me without hesitation.
