Don't let the name fool you, it does so much more than allow editing I use pdfFiller to sign agreements when I'm traveling and don't have the version of Acrobat where you can sign, on my computer. I actually like pdfFiller much better, because it allows me to edit things that Acrobat does not. I've utilized several of the templates that have been very well laid out. I was pleasantly surprised to see all of the templates and formatting options that are built in to pdfFiller There is really nothing not to like. I don't use some of the features, because we don't need them, but I can't say it's missing anything or has any issues.

I am a relatively new user to pdffiller, but have found the platform user friendly and does exactly what I need it to. Helping me modernise a lot of statutory requirements for e-signatures and template creations. When I experienced issues loading documents due to permissions through my work network, the support team at pdffiller responded quickly and continued assisting myself and co-ordinated with my employers IT support function to resolve it within 24 hours, allowing me to get on with my job.
