I’ve had a Kindle for years, and the only way I’ve ever put non-Amazon content on it has been through Instapaper’s Kindle delivery feature. But that requires saving things to Instapaper first, and then waiting for the scheduled delivery to my Kindle – not ideal if I need it go through now, and Instapaper doesn’t support PDF documents.
But I just discovered this handy set of apps and browser extensions from Amazon which allow you to send content from your web browser, computer, or email straight to your Kindle.
With the browser extension for Google Chrome, you can send any blog post or article on the web to your Kindle for reading later. The PC and Mac apps let you send documents by right-clicking on them, and the email feature will add the appropriate attachments to your Kindle’s library.
