I am going to discuss the program Calibre.
I have used the program for a very long time to read ebooks on my PC as I didn’t want to buy a device to have to do that.
This program makes that possible and so much more. Not only can you read your ebooks on your PC but you can make and edit them as well.
It can also convert from many formats to other formats as well and has a huge list of supported formats. The author clearly has spent much time and efforts
creating and updating this program for your pleasure.
Here is a video a short one that I made to help you learn about it, this isn’t intended to be a full instructional video of the program but highlights.
The author has a more detailed video of the program from an older version but it is extremely informative about the program.
Please watch it and support the author.
