What our customers say about pdfFiller

See for yourself by reading reviews on the most popular resources:
With the exception of the scam you have going to get people to sign up for your service... (i.e., On a holiday I came into my office to get work done quickly so I could then spend time with my family. I was soo pleased with your service as it let me upload a document and seamlessly edit it for 2 hours and the peace of mind that everything was working properly as your program continually provided feedback saying that 'all changes have been saved'. Then when I finally finished, after triple checking my work and feeling thrilled that I could go celebrate the holiday and be with my family, I selected the big bright button that says, Done!. And only THEN, after 2 hours of work, did you tell me, there is an error and I need to sign up for your program. You should be ashamed of yourselves. I was so excited to tell other people about your program and how well it works. After being scammed, ripped off in terms of money and precious time, I won't be telling anyone about your service. If you prefer to keep me as a happy customer, perhaps you will find a way to make up for this inconvenience (e.g., give me a discounted membership, upgrade my membership, some other kind gesture?) and correct this misunderstanding that you are covertly enticing people to use your program with an inconsiderate scam. I'd love if you followed up with me about this survey. Thank you. Sarah

Great Customer Service I signed up for the free trial and ended up not needing to utilize their services. I had thought I had cancelled it, but for some reason it never went through, so I ended up getting charged for the full year. I contacted their live chat and a representative named Anna was very helpful and got the refund processed right away. Thank you for being gracious and so helpful! I very much appreciate this company's customer service. I will definitely use them in the future! :)
