One of the best PDF filler's on the… One of the best PDF filler's on the market. Various ways to collect your initials and signatures, easy to use and well worth it... Think a bit pricey, but for what it offers it is highly recommended. SUGGESTION: Add a once off option - I only use it occasionally.

What do you like best? I enjoy the ease with uploading and editing files. As well as, the ability to change file types or combine documents. What do you dislike? The formatting can be time consuming and is hard to keep text consistent with original document. Recommendations to others considering the product: I would consider what you need it for and the price. It serves a good use for pdf editing and file management. What problems are you solving with the product? What benefits have you realized? It has simplified my study resources by allowing me to combine relevant documents.

I had an issue with the automatic renewal of my subscription smack in the middle of the COVID-19 pandemic. I have already been in quarantine for the past 4 weeks and cannot use the services of PDFfiller. I got in touch with the company and I immediately received a response from Anna who refunded the draft and cancelled my subscription. Because of the swift attention paid to my concerns, and the professional way in which it was handled, PDFfiller has earned my endorsement. *******
