Very user friendly site. I did lose my first document, since I didn't select the 'DONE' box first. Maybe just a little pop up message on how important that step is would be helpful.

Simply put, PDFFILLER has made my life a whole lot 'simpler'. I am no longer buried up to my eyeballs in paperwork (just up to my knees now! ha!) Since i began using PDFfiller, my desk is now, finally, Organized! Before PDFfiller - you couldnt even see the glass top on my computer desk., but now, since using PDFfiller, you can actually see every square inch of my desk! there isnt a single piece of paper 'waiting to be scanned', or filled out, so on and so forth. Which obviously has a huge impact on my ability to stay on track and stay focused! Needless to say I absolutely LOVE pdffiller! NO REGRETS!

So far so good. One change I would like to see, when I insert check marks and x's on a specific row, they come out unaligned. WOuld be nice if they were all aligned

Very well done product This is the best PDF modifying software I've ever used. I'm tempted to pay post the trial, I've used it like 15x since the first time I made a simple change.

PDF Filler service and support! The actual service platform is fantastic, but their customer support is also top notch. One of their service agents, Kara, took care of an issue I was having within moments, and all done in an incredibly friendly and professional manner. Kudos to Kara! ;-)

PDF Filler - Very Helpful PDF Filler is an easy way to find and download documents. However, being in South Africa and having to pay in US $ is just too expensive.
