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!

such an amazing site!! I love PDFfiller.com!! it makes editing forms so simple and easy! I would have rated 5 stars but I have a difficult time using it on mobile devices.. other than that it is the #1 tool I go to when I have to edit or even FIND a document using the search tool! when I finish a document I can send via TEXT, eMail, Fax, WhatsApp and so many more!! or I can just print or save for later. Thank You So Much for this wonderful site! I recommend this to anyone and everyone!!
