The PDF writer worked perfect for what I needed
Pretty easy to use and worked just as advised. I needed this to fill out PDF documents vs. printing them out and hand writing them. In addition finish product is neat and looks professional.
Don't have any negatives other than if it where free it would be even better, but the fee is small in relationship to what you gain.

For pdfFiller’s FAQs
Below is a list of the most common customer questions. If you can’t find an answer to your question, please don’t hesitate to reach out to us.
Documents sent by fax are able to be considered legally binding, especially if they contain a physical or digital signature. While traditional faxing often uses unsecured phone lines, electronic faxes are encrypted using a secure and reliable system to protect your data.
Is sending a fax more secure than email?
Faxes cannot be hacked very efficiently, but there are other reasons why the fax machine remains secure. Unlike emails, faxes cannot have attachment viruses. Even if they're slower than emails, email attachments can destroy your software and spread infections across the network.
Can faxes be hacked?
Although fax machines are way more secure than computers and emails, nothing can be completely impervious to hacks or malicious uses. Since fax machines do not use the internet to send their data, this just means that hackers cannot use the internet to gain access and information from fax machines.
How do I send a secure fax via email?
Go to the “Send fax” section and enter your recipient's name and fax number. Attach your PDF file to your message and send your fax through your service's secure fax technology.
Which is faster fax or email?
Is faxing faster or is email faster? Although conventional fax machines are typically slower, there are faster transmission technologies available these days. By contrast, emails will be sent regardless of whether the recipient is busy composing or reading another email.
How do I send a secure fax?
Go to the “Send fax” section and enter your recipient's name and fax number. Attach your PDF file to your message and send your fax through your service's secure fax technology.
