Still learning my way around. While it is helpful, it is not the most intuitive interface. Not bad, but could be a bit smoother and easier to navigate around.

Have been utilizing PDF Filler on my last 3 temp assignments and now purchased a 1 year subscription Have been utilizing PDF Filler on my last 3 temp assignments and now purchased a 1 year subscription and the benefits are awesome except the price for the subscription is too high for someone that only uses this software weekly or biweekly! being able to type into PDFs, upload easily, fax directly from my computer and send to sign feature. Have been utilizing PDF Filler on my last 3 temp assignments and now purchased a 1 year subscription. I also like the black out feature and the way the software notifies you when someone opens your emailed over or faxed documents. The Price is way too much since i dont use it everyday like real software. Also, i bought a subscription and to use the advance features i have to pay more which is ridiculous since i already paid.

Good Features but you have to nothing is for free I was so delighted by how easy and intuitive this pdf editor is to use. You upload a word doc you want to convert to pdf or a pdf file that you want to edit. You edit and are very impressed. Until I tried to save. It's browser based but it basically does everything you wish you can do to a pdf file. The interface is very intuitive and can get you going n the first sitting. It will let you edit but you will be unable to save your work until you subscribe. Not another free trial!
