If you are using the ealier versions of Kindle and want to read PDF files, you may need to convert the PDF to Kindle (TXT) first. HTML, DOC, DOCX, JPEG, GIF, PNG, and BMP are usable through conversion. The fourth generation Kindle, Kindle Touch and Kindle Touch 3G are able to display Kindle AZW, TXT, PDF, unprotected MOBI, and PRC files natively. Earlier versions could not generally read PDF files, but Amazon provided 'experimental' conversion to the native AZW format, with the caveat that not all PDFs may format correctly. The Kindle 2 added native PDF capability with the Version 2.3 firmware upgrade. The first generation Kindle can read only unprotected Mobipocket books (MOBI, PRC), plain TXT files, Topaz format books (TPZ), and Amazon's proprietary DRM-restricted format (AZW). Amazon Kindle eReaders enable users to shop for, download, browse, and read e-books, newspapers, magazines, blogs, and other digital media via wireless networking. Amazon Kindle is a series of eBook readers now in its fourth generation.
