What our customers say about pdfFiller
See for yourself by reading reviews on the most popular resources:
It is a little hard to figure out how to size and arrange the words so they will all appear on the printed document. I had to redo this several times.

Aside from the cost associated with its use, I love PDFfiller! It is easier to use than the typewriter function in Adobe Acrobat and I could place text exactly where I needed it. One other recommendation is adding a spell check when finishing up the document. Respectfully, -RPS

What do you like best?
As a beginner, I was surprised not only with the fact that PDFfiller was so much easier to learn and use than the Adobe Suite but also at the range of capabilities on offer! From my first use of this online program I found new pleasure in dealing with .pdf files. I now use the program Every Single Day to create, manipulate or convert files that used to sit waiting, sometimes for days at a time, to be done by the one or two people with access to more expensive and less user friendly programs. Now I have a new "can-do" attitude to the workings of .pdf files. I can't recommend this online tool enough and it's so affordable, you can buy a license to use at home. Great product, lots of advantages. You will not look back, you will not regret this purchase.
What do you dislike?
The user Interface could do with being a little less busy. A streamlined interface and a compact "how to..." would take a 9/10 to a 10. It just needs some tweaking and it's perfect!
Recommendations to others considering the product:
In my opinion it is definitely worth spending the small amount to upgrade to the paid version!
What problems are you solving with the product? What benefits have you realized?
Administration issues generally...adding text, file conversion and commenting on documents...are all problems that I had to either pay to have done elsewhere or ask for an expensive subscription that was never in my budget and wouldn't be approved if I had asked.

Good layout and simple to understand
Good layout and simple to understand. However, while editing I realised that it does change the original size of the item when it is converted the format.

Excellent features
This allowed me to add to my PDFs that I couldn't before.
This product saves time. I was trying to find something that lets me add a text box or even text to my pdf files. This product does this! Very cool!
I can't think of anything. It does what I needed it to do. Excellent and easy to use for my documents.

I have NO ablity for photoshop
I have NO ablity for photoshop, etc. But this software is easy to use and I can easily edit the few things I need to do. Highly recommend it for those who aren't to tech savy.

Smooth fillable process
Smooth fillable process. It's just the end of the process, saving the document and accessing it that I still need to get used to. I don't feel too comfortable as I feel like my documents are not easily accessible if I forget my password. I guess it's a matter of getting used to. Also is there a charge sometime in the future for this?

This review is primarily for the customer service. This company had extremely quality customer service. FAST responses. I would definitely recommend trying it out for that alone, they will work through and address any issues you have. You won’t be disappointed. Great job.
