Blown away. EZ to use once figured out, and quite intuitive. Only a couple surprises where the DOS commands didn't always work e.g. cut and paste. The shift/delete cut worked, but the shift/insert paste didn't. Just need a little time to find my groove. All I can say right now is: Bye, Bye handwritten forms. dc macdonald

This site is truly amazing. I am a 66 years old Vietnam Veteran and Retired U.S, Marine. Currently filing for PTSD and was able to fill out the VA form exceptionally easy. I purchased a 1 year subscription, in that I felt it would be worth it in the future. I wish this site had a method of informing others about the services. I searched the web and stumbled across this site. Further, I initially had questions and was able to speak to a live person. His attitude and willingness to help, sold me and I purchased the services. Once again, Thanks. Doug U.S. Marine Corps, Retired.

I love it for the most part. Just wish I could send a document to a person without knowing their email (ex. directly to their Facebook account) with the ability to view and sign not edit the document. Other than that, it's been great!

New to this site...just begun 30 trial New to this site...just begun 30 trial. So far so good. Getting used to it but already I like much better than Adobe.

This program is the best viewer and editor of PDF files that I found online and free. It is a utility or extension that we can add to our chrome browser to open directly from our inbox, those files with PDF format, without the need to invest great efforts in downloading and installing heavy programs that deal with that work. I mean, it's so light that its discharge is super fast. Once the extension is installed I must refresh myself mail, I believe that this work should do directly the inclusion process of the extension in chrome. It is hardly a detail if we compare it with the great advantages that this product offers us.

Once I figured out how to use the eraser feature, this software was immensely helpful. Occasionally, it did not print the lines on Schedules K-1, but eventually it did. I have now successfully downloaded a file from the IRS and merged it into the file I was working on with pdf Filler. I really like this software.

The Portable Document Format or PDF is a common document format for various reasons. It's accessible from any device, so you can share them between devices with different screen resolution and settings. It will keep the same layout no matter you open it on Mac computer or an Android device.

Security is one of the main reasons users in the business and academic world choose PDF files to share and store information. PDF files can not only be password-protected, but analytics provided by an editing service, which allows document owners to identify those who’ve read their documents in order to track any and all potential security breaches.
