Lifesaver!! Lifesaver!!! I am not always able to print documents, fill, them out, sign them, and then scan them in and email them to recipients. This program allows me to skip most of the steps.

Meralis Acevedo Meralis AcevedoI was able to find the form I needed. The only thing is that it was a little difficult figuring out how to use all the features it has. How to modify the text was not something I was able to do through erasing. Maybe using PDFfiller more often will help me maneuver the site with time.

What do you like best? I like how easy it is to upload documents and make the necessary changes to the documents that require modification. I have completed forms for students and uploaded signatures easily and have been able to successfully download documents as well. What do you dislike? I have noticed that sometimes when I upload a document that I previously edited using PDFFiller, it makes my signature super bold and not easily read. It changes the format automatically and I have to download a new document to upload and add a signature. It seems like once I utilize PDFfiller and download the document the format of the previous e-signature is no longer compatible. What problems is the product solving and how is that benefiting you? We had to provide e-signatures to international students on their I-20 documents and PDFfiller has been an integral part of that process. It has been very accommodating for me to upload documents and sign them electronically for students and then easily download them and email them back to the students.
