Push to Kindle
This is the official add-on from Amazon that will let you deliver web pages, blog posts and any other web content to your Kindle Reader or any of your mobile devices that have the Kindle Reading Apps installed.
It will transfer only the actual article and not the distractions. You also have an option to select a portion of text on a web page and push it to your Kindle.
You can turn on the option to archive content in your Kindle library and you can then re-download your sent items any time later.
