A bit difficult to navigate…
A bit difficult to navigate through/enter updates unless you use this on a regular basis. Once the memory kicks in, it's a GREAT tool for making easy changes/adding necessary information.

PDFfiller is great if you need to edit/change PDFs
This software allows us to fill out and share PDFs, vastly cutting down on our printing/scanning song and dance.
No real negatives other than I wish it were free.

I have used PDF filler to change dates on my job seeking paperwork.
I use PDF filler to fill in work forms. I love that I can get my signature easily, and ask others to sign forms! This is great for school paperwork.

I have trouble using the pdffiller on my laptop, I can not upload b/c the screen is not wide enough to get to the click button. I can on my desktop when I go into the office. Sometimes the app does not give me the ability to save or download - I have to play with it back in forth before it will save as a fillable file. But my biggest issue is using my laptop when I work remotely and I have to use it. Thanks for inquiry and the survey to give me the opportunity to voice a concern.

So helpful. I can fill out the form instead of scanning, printing, filling out, and then scanning again so that I can send it back. I did try other programs... this one is by far the very best.
