Online document sharing site Scribd is today starting a transition of from Flash to HTML5, according to the company's CTO, Jared Friedman. At present, most PDF, Word and PowerPoint files uploaded to the site are still viewed in Flash containers, which help to preserve formatting while adding controls for flipping pages or zooming in and out. Converted documents should also preserve their formatting, but are read as one long webpage, with a new bookmarking feature for preserving places.
