this great! I mean it. So many unuseable, scam pdf form sites ... I just completed a form that failed at other sites including government sites thanks!

I am unfamiliar with these programs and so I struggle. I was unable to increase the size of the text in one of my forms and it looks awkward on the form after printed.

PDFfiller is so user friendly. It helps immensely as a private practice owner where I need to fill-in pdf documents, convert to other formats, and insert verified signatures. I would recommend to other business owners.

PDF Filler is very convenient and well thought through. Now, if it only integrated with my tax return online service provider and auto-populated forms, ditto all others, it would be perfect.

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 takes a minute to get use to but I think I'm getting it. Trying to use to send files to the government. I was trying to figure out how to just save a pdf filled out.... there are so many pop up windows.

I use this to do my tenant leases Overall, I have to have access to a software program like this. Some landlords issue leases on ancient old pdfs that are hard to work with. This program allows me to alter, merge, and arrange these in a fairly intuitive way. It took a minute for me to be comfortable with the document storage setup that pdffiller uses, but I am happy with it bc I can access these documents from anywhere! I love the way you can just insert a text box, or erase. Wow its so nice to be able to do this with documents. I find merging to be hard. I had to get help early one Sunday morning from support. The support was there and ready to instruct me. It just wasn't intuitive. I might even have to ask how to do it again.
