I use PDFfiller for so many things. Filling in documents like applications, signing documents without printing them, modifying PDF files. It has been an invaluable tool.

I do like the ease of use as this is the first time I have used a PDF application. I have just started using Adobe and unfortunately I think I like that better. Not positive yet.

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. *******

Great Tool & Responsive Customer Support I've been using pdfFiller for several years now, and find it easy to use to make quick changes to documents. It has improved over the time i've used it, as originally the font didn't always match and some sections couldn't be moved or deleted, but it now seems to have these features. On a couple of occasions I've needed to raise a support ticket, and the team are very responsive, helpful and provide a resolution quickly. The reason i've not given it 5 stars is because last year i had to edit a 60+ page instruction manual, and spent many hours over a couple of weeks trying to get it to work, but it kept crashing and not loading all the pages, which was frustrating and wasted a lot of time. In the end i gave up and redesigned the manual using another platform. Overall, great for simple editing and the basic package is good value for a small business.

I needed a HIPAA compliant PDF editor and found this one. Lost the document I was working on but was helped by chat and got it back. Very relieving!
