It was a little frustrating for me figuring out how to use the program. This should improve with use and guidance. It would have been helpful if I had first down loaded the "How To Guide". Thanks for a great program.

It is great to use for signing documents on the road with my phone, but i am concerned that the confirmation stamp is not widely accepted as a form of a signature.

pdfFiller Review Overall, PDFfiller is an excellent solution for digital signature, document management, and PDF editing needs. I highly recommend this platform for any user looking for a reliable and convenient solution to work with PDF documents. PDFfiller is an excellent online platform that I really enjoyed using for its features of digital signature, document management, and PDF editing. I used this platform for more than a year and I was impressed with its ease of use and the speed of its features. The negative aspect that I noticed on PDFfiller is that it is not always easy to find advanced editing options, especially for beginner users. This can lead to some frustration at the beginning, but once you get familiar with the interface, it becomes much easier to use.
