So far so good. I like the many options for editing and moving documents and information. The site is fast and I like how you can work on pdfs in so many ways!

I really like working with the filler although there could be better control in the editing. I believe it could be more intuitive as to the fields which are potentially fillable and place the cursor within those lines automatically. It is fussy to try to line it all up.

First time use for the pfdfiller and…it was easy to follow
First time use for the pfdfiller and the instructions and examples were very logical to me. Worked great!

Interesting product the pdfFiller. I would like to learn what else I can do with this software. The new look for the PDF is wonderful but I don't know if I would be able to use the old PDF from Microsoft. It seems I just paid my Microsoft subscription. It seems that the PDF is a software of it's own and doesn't come with the Microsoft Tools.

Easy accurate and helpful!
This is an awesome tool for making even the most unprofessional professional. It is easy, concise and easily editable. It is well worth the price.

A proper company
PDFfiller apparently thought I wanted a subscription to their service after trying it out once. I did not want that, however, and wrote to them to cancel the payment. They cancelled right away, no questions asked. You know a proper company when that is the procedure.

We were trying to print a government…
We were trying to print a government form. It kept going to buy a package wjhich we already had. Kara was able to one time purchase the supream package so we could print and then she bot us back on the basic plan. She was very helpful. Thank you!!!

This is great. We don't have a printer and with the Covid shutdown, we can't just run to friends house to print like we used to. Using PDFfiller, We don't have to print at all, we just fill out the form online and send it off completed.

It is a convenient application
It is a convenient application which allows professional appearance to forms. I am a little concerned about shared documents which need editing if the recipient is not a subscriber.
