I absolutely love PDFfiller. It's my go-to! I don't own a printer, and generally don't have time to get something printed, fill it out, scan it, email it off. I save SO MUCH time using PDFfiller. And i love the results. I love how i can add my Signature, change fonts and sizes, etc.

I was able to do what I needed but I am not sure about future applications. Also, I thought I received a 70% Discount for signing up annually but I did not receive this.

What do you like best?
I enjoy the way PDF is easy to use and allows us to send out documents quickly. We operate a few different locations remotely and we are able to send out important documents require signatures in less than 5 minutes! Support is great when needed but we seldom have any issues.
What do you dislike?
There are not many issues with it. It would be nice to be able to copy/duplicate documents prior to merging so we do not have to upload them once again.
Recommendations to others considering the product:
If you work remotely, I highly recommend this program. We love being able to email employees and clients in a matter of minutes for documents requiring information on their behalf.
What problems are you solving with the product? What benefits have you realized?
We are solving travel time and time with paperwork with all of the documents be readily available with just a click. Prior to PDF, we were having to meet with new employees for paperwork. Now, we are able to email them and have them sent back for processing. Our time is being used in a for efficient manner.

Simple tool that increases productivity in office I'm a software engineer and have to deal with many documents everyday. Having a simple tool that has all the features needed for me to edit and handle all my documents makes my life easier. At the same time it saves me time to look up new tools and ways everyday. The UI is simple and intuitive, and it's easy to attach files, download and share it as needed. Overall it makes me more productive in office. My favourite feature is the electronic/digital signature feature. As a person in the IT department, I have to work with numerous documents and sign many of them. And this tool made that really easy for me. Also, the signature looks blended out and not out of place. Other than that the merging tool and conversion tool are also very helpful. Depending on my needs, sometimes I can convert a ppt into a pdf for easy access or for sending it to anyone. I also get to attach different pdfs together in whatever order needed. I don't have any major concerns. The only small problem I've had is regarding character recognition from scanned pdfs. Sometimes it is not entirely accurate. Though it is manageable for me.

pdfFiller Has Never Disappointed Me - They are My Trusted Admin Source pdfFiller has never disappointed me with the choice of fillable forms and the ease of completing and saving the documents. For Form document completion, they are my Trusted Administrative Assistant, and I would not recommend any other company for the service they provide.

I am not computer techy I am not computer techy - and I have been able to figure this out to do what we need. I am sure there are features that I have not figured out yet - but I stay very busy @ work so doing a webinar would be tricky to schedule.
