What our customers say about pdfFiller
See for yourself by reading reviews on the most popular resources:
I really like the fact that I can download PDF files, fill them in and save them on my computer. Once they are saved I can then print them or go in and change them.

At first, I was outraged that I had wasted 2 hours to fill in a form, only to realize that I couldn't afford what they were asking for me to print. So there was 2 hours wasted.
I sent an email to PDFfiller, explaining my outrage, but then they gave me 30 days free! So I could then print out my form, it wasn't a waste of time after all!
Great customer service.

What do you like best?
I mainly use PDFFiller to fill out and sign forms. The auto-alignment tool for text blocks is very useful. I found the PDF to Word conversion procedure very powerful.
What do you dislike?
The limit in the number of pages and the size of the PDF file often forces me to divide the PDF into several parts before upload.

This is a great app, I just can't afford it right now, that's all. It's well worth the investment if you can afford it though! Trust and believe that! They will give you a free trial period. So, try it and you will see! It really is a great PDF app!

The software if very intuitive. No wasted time trying to figure out how to use the software.
Not having to update the software periodically or pay high Adobe license costs.
Drag & drop features and drop down menus work flawlessly. I can have a colleague use the software and not have to explain how to use it.
May be thatI haven't had time to really look at this, but I find that I have a lot of information in my main folder. Intuitive or simple organization structure would be nice. I'm usually in and out of there to get what I need done, but I did have to search a few times and thought I needed to clean up that home screen.

A good all rounder for filling pdfs and signing forms
pdfFiller is a useful tool that lets me fill, sign and send client contracts
I like being able to add text to pdf forms, then email,download or print the completed forms
I have to be honest, it's a bit clunky and takes some getting used to

Actual Customer Support
I sent a question in via their form, and honestly expected a "word search" systemic response. Not only did I get a issue-specific response, the corrective actions were clear and documented with screen shots, making it easy for me to correct my mistake and move forward.

this is the best product I could find…
this is the best product I could find for converting a pdf form into something fillable. I don't need to use this regularly so better if you offered a annual usage limit package- say 12 uses a year for $12.00- which seems fair and reasonable to you and the customer. (If you take this idea up, please do let me know)Ross Harling

What is a Digital Certificate and How can I View it?
The usage of a digital certificate is a kind of authentication to keep track of all changes made in PDF files. It comes into action after the complete document is signed by the last authorized certifier.
In case the changes were made after signing the document, it will invalidate the digital certificate.
To view the certificate, one needs to open the document with Adobe Acrobat Reader. The certificate will be seen under the signature panel. By clicking on this link one will see all additional details about the signer and document itself.
