pdfFiller scores top ratings on review platforms
Once I figured how to use PDFiller it was great. It worked as I hoped and it served is intent. If the occasion arises again I will definitely use PDFiller.
Thanks for your customer service attitude and your expeditious response to my requests and clarification.
I find it so much easier to edit documents, and save for later. Being able to share and easily find them. As well as changing page lay outs for presentations too.
It would be easy and helpful to implement: A tool which allows you to pick the colour you want (and be able to use that colour to erase, paint and write). A auto text-detector and erase
I am happy with how to fill out the health claim form template. It is user-friendly and reliable. It is a little slow to open documents and I waste some time looking for the right one. I don't like the organization system and I haven't figured out Templates. I am not looking for a practice management system so I like buying only what I need. Overall, I like the app and I paid for a year subscription.
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.

easy
it would be great if I could just give the 5 stars and get on with my life its great easy to use I have no suggestions it is what I was looking for thank you
I never leave reviews, but Elisa from the 'chat' help was so helpful that I am leaving a review!!! I usually avoid chat help on websites, but Im glad I stumbled upon Elisa. Truly helpful and very efficent. Just became a happy customer
I needed to use the service for an application! It was only needed once. The day I was going to cancel it due to no longer needing the service the money had already come out of my account. They immediately refunded it and even offered a discount if I wanted to continue using it. I highly recommend it was an easy to use service with many benefits packed in. Customer support replies quickly and they are very professional.
PDFfiller is very customer focused. When I emailed them they responded immediately and followed up with me to assure my questions were answered. I would highly recommend this company.
