I enjoy the simplicity but am annoyed that you can't use certain features without paying a higher price. $80/year is pretty high for a basic subscription.

I've been using Adobe for all my PSF editing needs, but this program is so much easier and faster, I can't believe I wasted my time and $ on Adobe for way too long! so glad I found this program!

I am really new at trying this out. The fax feature sounds like it would be very useful to me. I am very interested in learning about all the features offered through this service.

It works great, but is very expensive for how often I will use it. I wish there was an option to purchase some sort of punch card or to pay per use instead of paying $20/month, which is outrageous if you are not using it daily.

Really like the program. As mentioned. I use it to update my catalog prices and images for printing. That it allows me to erase certain parts of my document and insert others. I couldn't figure out how to add my prices to an already made catalog I use. That I have to come out of the document to look at the completed changes then go back in if it's incorrect.

You know for those of us that need that… You know for those of us that need that little extra help with these unfamiliar online tools. PDFFILLER online help really made me happy with my choice. They were quick to respond and help me getting familiar with the site as I edited a document.

Combining two files was relatively easy once I read... Combining two files was relatively easy once I read the How to Guide three times to figure it out. But editing text in the file resulted in a change in the font that was not particularly satisfying and could not be corrected.
