K7 also reminds me of eFax which also offers free faxes by email. What I like about K7 is the voicemail offering.
I wanted to use this opportunity to talk about a free tool I use in conjunction with eFax called TinyPDF.
The problem with eFax is that they send you faxes in their proprietary image format “.efx”. If you wanted to send this file to someone else, in order for them to view it, the recipient would also have to download and install eFax. You also have to upgrade to the pay version to convert to “.pdf”.
The TinyPDF software sets itself up like a printer so almost any document that can be printed can be converted to “.pdf” including MS Word Docs. Just like a printer you can specify what pages you want converted over.
It is totally free, only 586kb in size, no nags, no page quantity limitations and no watermarks like you see in other “free” pdf converters. The only drawback is it is only available for Windows users. No Apple : (
There are many offices and business that live and die by the “.pdf” and this is a great tool to convert files into a format that most office workers can view.
