title: Google Doc Viewer: Which formats are really supported?
body: <p>I'm using Google Docs Viewer to embed all kind of documents. However I am having trouble to find out which formats are really supported.</p>
  
  <p>On the offical Docs Viewer website (<a href="https://docs.google.com/viewer">https://docs.google.com/viewer</a>) Google links to a nice list of all supported formats. The following formats should be supported:</p>
  
  <ul>
    <li>Google Docs</li>
    <li>Google Sheets</li>
    <li>Google Slides</li>
    <li>Google Forms</li>
    <li>Google Drawings</li>
    <li>Image files (.JPEG, .PNG, .GIF, .TIFF, .BMP)</li>
    <li>Raw Image formats</li>
    <li>Video files (WebM, .MPEG4, .3GPP, .MOV, .AVI,  .MPEGPS, .WMV, .FLV, .ogg)</li>
    <li>Microsoft Word (.DOC and .DOCX)</li>
    <li>Microsoft Excel (.XLS and .XLSX)</li>
    <li>Microsoft PowerPoint (.PPT and .PPTX)</li>
    <li>Adobe Portable Document Format (.PDF)</li>
    <li>Tagged Image File Format (.TIFF)</li>
    <li>Scalable Vector Graphics (.SVG)</li>
    <li>PostScript (.EPS, .PS)</li>
    <li>TrueType (.TTF)</li>
    <li>XML Paper Specification (.XPS)</li>
    <li>.MTS files</li>
  </ul>
  
  <p>However, if I try to embed Image files or Video files for example I will get the famous 'Sorry, this type of document is not supported for viewing' error.</p>
  
  <p>So my question is: Why doesn't it show these files and which formats are really supported? </p>
  
  <p>Example: JPEG (not working)</p>
