Google Labs launched an experimental tool called Swiffy.

Swiffy converts Flash SWF files to HTML5, allowing you to reuse Flash content on devices without a Flash player (such as iPhones and iPads).
Swiffy currently supports a subset of SWF 8 and ActionScript 2.0, and the output works in all Webkit browsers such as Chrome and Mobile Safari. If possible, exporting your Flash animation as a SWF 5 file might give better results.

Chromium’s blog announced that the latest Google Chrome dev build for Windows and Mac includes a plug-in for viewing PDF files. The plug-in can be enabled by going to chrome://plugins/ and clicking on “Enable” for the “Chrome PDF Viewer” plug-in.

and On February 17, 2011, Google OS said,

If you use Google Chrome and you haven’t disabled the built-in PDF plugin, you can now open PDF attachments from Gmail using your browser’s viewer. Just click “View” next to the attachment and you’ll notice that the PDF file opens faster and it looks much better.

The Chrome PDF plug-in is faster than the Google Docs previewer, its rendering accuracy is better, and you don’t have to change settings anywhere for this to take effect. Just use Gmail in Google Chrome and the ‘view’ link will automatically open your file in the Chrome PDF viewer.
The change is also nice because Chrome’s PDF plug-in actually lets you print, unlike the previewer which can only manage recursion printing (it generates a PDF of your PDF).

• View PDF, PPt and Tiff online with Google Docs, even you do not have a Google Account or you do not want to login it. and you can embed the online documents into your own web pages.
• Google Docs add OCR support to PDF and Images, so you can OCR your scanned PDF, Fax, Images without any fee.
• Built-in PDF Reader for Google Chrome, view PDF just like view html. Chromium’s blog announced that the latest Google Chrome dev build for Windows and Mac includes a plug-in for viewing PDF files. The plug-in can be enabled by going to chrome://plugins/ and clicking on “Enable” for the “Chrome PDF Viewer” plug-in.
  When you click on a link to a PDF file, Chrome no longer opens the file using the Adobe Reader plug-in. Instead, Google Chrome uses a basic PDF viewer that lacks many useful features like pagination and bookmarks.
