I have been using this program for almost 2 years now and it is amazing! I have uploaded all of my work documents/forms so I no longer have to hand write every single thing. Not to mention I am saving money by not having to purchase any paper and more importantly I don't have to purchase any printer ink.

This was super helpful for when I was… This was super helpful for when I was applying for a job and then filling out the pre-hire paperwork. As I have not had a good source of income during this process, I was very glad for the free trial.

Very speedy response time! I work for a Charity and did not cancel my subscription in time. However, true to their word, pdfFiller responded to my request to refund (didn't have the correct form I needed) within an hour. I was really impressed and very grateful that they will refund this charge. Even though I didn't use them, I would definitely recommend them. They came across as quite honourable which makes a change these days...
