Amazon Send to Kindle 

Kindle is one of the most popular e-book reading devices on the market. This program allows you to send different types of files to read them on your Kindle device.

Doing so is really easy. Of course, you need to have an Amazon account and a Kindle device. In this regard, it is not necessary to have the physical e-book reader sold by Amazon. You can have the Kindle application installed on your Android- or MacOS-based phone or tablet, and send the corresponding file(s) to it. This is a huge advantage since it allows you to read the sent files on different devices depending on your needs.

Sending the files is very easy too, and there are several ways to do so. First, after installing the program on your Windows-based PC, you can choose the file you want to send using Windows Explorer. Then, right-click on the file and choose to Send to and Kindle in the drop-down menu. A dialog box will appear, asking you to set the device to which you want to send the file. Another way to do this is through the Print menu of the file. You can choose this option, and instead of selecting a printer, you can click on the Send to Kindle option. Finally, you can open the program and drag-and-drop the file into the program's interface. The aforementioned dialog box will appear in all cases.

A very nice feature is the possibility of formatting PDF files into the Kindle format. This will allow you to fit those files to the screen of your device, thus making the reading experience easier. Also, you can use most of the Kindle tools, such as changing the font size, set markers, and so on.

My only complaint is that this feature is only available for PDF files and not for Word, TXT, and other formats. Let's hope that the developers correct this is future versions.
