Amazing! - Total lifesaver. Does what it's supposed to, and even does most of it for free (I've used it to fill loads of forms and submit documents and never had to pay for anything)! I have no hesitation in recommending the PDFfiller service.

I've used pdffiller almost a year. Works pretty good.
Available anywhere. Document storage is good. Login in is easy. Options are many especially what can be done after the document is finished.
Time to load documents Too many clicks (four) to get it to print. Can't arrange folders to my liking.

Easy to use!
Service was easy to sign up for and use. There were clear menu bars showing the tools and how to use them to edit my PDF files. Would recommend to others, would keep the service if I didn't already have the full paid version of Adobe PDF I only needed this one time on a computer other than my own or would have continued my subscription.

is there a way to access a pdf document on my laptop harddrive or is it always required to email to pdfFiller?
is there a way to embed text comments via the keyboard ?
2020-05-19
I would love to attend a webinar eventually, but time right now does not allow it. I have been extremely pleased with pdfFiller and recommend it to everyone I know who has to fill out a lot of forms.
Maybe slower than hand writing , but legible which is extremely important. My biggest issue is somehow I have two accounts with other documents saved and do not know how to merge them. That was my problem not realizing i had an account already. Thank yall so much!!!
