I am not very computer literate although the system is simple enough to work with that I can do everything so far. I need to edit a scanned document and this is more challenging any help would be appreciated.

Love this program! It allows you to download any document and make it your own. No more handwriting which leaves room for errors. The only part that confuses me is the saving of a document to be used over and over... haven't quite figured that out yet.

Easy Auto-Renew Subscription Refund
Like most sites that offer small services with yearly or monthly subscriptions, you most likely run into the "auto renew subscription" headache. While it is frustrating (as this happened to me with PDFfiller), it is always nice to have a little forgiveness. Before I disputed the transaction with my bank I "calmly" contacted PDFfiller support asking if I could be refunded for this un-consented transaction of $72. It only took 5 mins with customer support to give me a full refund. And for that hasty/easy relief they gave me (as well as a refund with no questions asked) I give them 5 stars. Also, not to mention, it is a great PDF filling software.

Some of the advanced feature require a great learning time from the end user. Sometime you would not get expected results while converting a Pdf to word in terms of change in formatting which is difficult to edit. Sometimes the tools is slow while working on large size files.

It's a great experience and many options to get your forms completed in the manner you want them done. The option to save them for later and email them to others to edit is definitely a perk!

Help me get a deliverable done in time
I've only used it for 30 minutes or maybe an hour but it has helped me merge a bunch of PDFs that I was having issues with and needed t get dne iin time for a contract delivery.

Works well
Works well. Just wish there was a way to sign without the added date and time and logo. No one cares about the logo, they just want a signature that appears real. I still have to print, sign and scan, because of that one issue. Kind of makes it worthless to be able to fill out on line.

As an accountant
As an accountant, even one who does not prepare taxes, this has turned out to be a life-saver for me with all the POA's and other forms that need to be filled out and signed. Thanks pdfFiller!
