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.
