Just what I was looking for. Liked the smart software that figured out what fill-ins of IRS forms were in teh wrong spatial location in a box and which ones needed to be copied to later pages.

Easy to use. Easy to use. I struggled a bit lining up fields with each other, but I guess there is an easier way of doing that than I am doing. For a first timer, I was happy with the experience.

I liked their services I liked their services, but didn't need them long term. I had thought that I had canceled my account right afterward, but still was charged when the trial period was up. I contacted them on a Sunday, expecting it to take a few days and be a nightmare. Even though it was the weekend they had it taken care of and refunded to me within a few hours! I would definitely use them again because of how trustworthy and understanding the staff was. Good job PDF Filler Team!

The NC OTP was a perfect match and was all that we needed to get the buyer and seller on the same page. Although it wasn't used by the attorneys it could have easily been used since it was identical to the one they used.

It does what it is supposed to do It does what it is supposed to do. I don't like having to put the 4 digit code in.....maybe that is just for trial??? Easier than Adobe.

Answer: A: Answer: A: There are no known exploits currently able to infect a Mac through a PDF file. There have been some within the last year that pretended to be a PDF file, and would open a real PDF after installing the malicious payload, but those should be blocked by the OS at this point.
No. A PDF file cannot contain malware that would affect iOS, unless someone discovers some currently unknown vulnerability in the handling of PDFs on iOS.
How can I tell if a PDF file I was sent contains a Virus? One way to determine whether a PDF file you were sent is infected by a virus is by uploading the file to VirusTotal. The results from VirusTotal are not 100% accurate, so you need to be cautious. There is also PDF Examiner.
Though not always vulnerable and infected, but some PDFs can have virus or another hidden malware. Being the most common email attachment, PDF is commonly targeted to breach computer networks. Advanced forms of PDF malware are not easily detectable by Secure Email gateways.
No. A PDF file cannot contain malware that would affect iOS, unless someone discovers some currently unknown vulnerability in the handling of PDFs on iOS.
