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.

Solid, provides the service you need Easy to use. Mostly used for inserting signatures. Sometimes the signature block format gets distorted (inserts as a code).

Excellent Product Makes nonstop-filling-out-documents projects go by quickly. Rare online product that not only works as intended, but includes most of the features you wouldn't expect it to have. The interface and options are also shockingly seamless. It's easy to print, save, share, download, etc pretty much any document from any screen.

Did you know?

Every month, I receive an encrypted Portable Document Format PDF file with my payslip. Without providing my password, I cannot open the file at all. Does that mean whoever created the PDF file has access to my password in a recoverable format? Or can they encrypt the PDF by using the hash or some other non-recoverable function?
