This program is awesome. Not only does it solve the problem of not being able to type on pdfs, you can also sign a form that is on your desktop computer on your phone. Amazing.

PDF filler seems to be very useful. Is/was slightly difficult to figure out but once understood is fairly easy to use. Unfortunately the price is too high for those of us on fixed income. Is there anything lower cost for disabled seniors? Please?

Easy to use & Quick My business is all about paperwork. Everything is time sensitive and I could not get things done without PDFfiller. I use it daily. The ease of use is so important to me. I don't have time to learn difficult programs. Easy to upload docs from anywhere, rearrange pages, make corrections, save as PDF and save or email. You can name your files and go back to them when needed. The dashboard is easy to navigate. I have used this software for years and they are always improving and adding new features. I have had trouble uploading an occasional document but customer service fixed the issue each time. Sometimes my document is too large which is frustrating, they have a size limit. Also, a document with signatures from another software company (e-sign) sometimes don't come thru.
