I have had to upgrade twice to professional and just did again so I could use the features. Billing does not show that the upgrades were put in place.

Quite good!Only after I finished, did I see that the date next to my signature at the bottom was misaligned and printing over some text on the form. So, I had to go back to edit that. Very helpful tool, though!

Love this!!! Can erase words from PDF's.
You will love this program!!!
There is an eraser feature that is the best thing ever. This allows you to change a PDF document. How many times do you need to modify a document, or wish it said something different, but don't have an editable version. With PDFfiller you can erase the verbiage, and replace it with something else. You can also easily place your signature on documents too. You can upload you own personal signature too.

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.

Enjoyable and functional.
Ease of use, functionality, and security features. I like the automatic lock out for the encryption and I enjoy the accuracy in identifying areas that need to be filled out.
That I cannot move folders within folders under the encrypted area. I would like to be able to drag folders into other folders. I would also like to merge more than 5 documents at a time.

I was looking for a PDF system that I ciud use to fill out and sign documents that I could across platforms. This PDF FIller seems like the best and most reasonably priced app.

So far, so good
So far, so good. Does as it claims to.Some of the functions e.g. merge could have more accessible controls (you have to gone into a few menus), but when found they do their job well.Maximum document size is 25Mb so if you have a bigger document you have to use another online splitter and go from there. Don't really see why that functionality could be integrated though.
