I mainly use it to edit papers for my teaching position; it's been very useful to not alter the original format while adding my view point freely on the document.

It can be great, but it's a little buggy at times. The signature feature often crashes the signer's device, whether mobile or desktop, and the API integration with Zapier is very finicky as well.

I have only just started using PDFiller.com and I am very happy with the product. My only compliant is that I was forced to subscribe to it without the option of a free trail etc When I did a search on the web for a free PDF Editor, PDFiller.com was one of the websites that popped up, I edited my document (which was a theory paper that I had already spent hours on !!) and when it went to saving it I could not without paying for service... so not a free PDF editor!!! And you can not subscribe month to month, you had to pay for a full year. I know that is business but very deceiving!

I'M disabled, and confined to a wheelchair. I'm not able to get out, and look for a place that will agree to fax things. I have arthritis real bad, and it is painful to hold a pen, and fill things out. The ability to do all of this for my nurses, and care-provider's, with PDF filler online is a true blessing. Thank you, so much!
