Apple Keynote doesnt play in most of my browsers I made a presentation with a simple transition effects and tried to export that presentation to HTML format.

But when I tried to open it on my MacBook, I found, that it doesnt work in Chrome, but works fine in Opera, Firefox and Safari. It show me the preloader and the black screen then in Chrome.

And then I tried to open it on Windows and found, that it works ONLY in Firefox... Chrome, Opera and IE8 dont want to play it...:( And show me the black screen only.

Is that normal or I do something wrong? I need it to play in IE and Chrome for most of our employees...
Export to QuickTime / Movie

Your best option is to export the presentation as a QuickTime movie. This will create an MPEG4 formatted file that can be played on a wide range of devices and operating systems:

Keynote.app > File (menu) > Export To… > QuickTime



Compress with Handbrake

After exporting your presentation, consider compressing the resulting movie file using Handbrake. Handbrake will dramatically reduce the file size and broaden the number of supported playback devices.

View with Browser or VLC

Many web browsers across different operating systems can also natively play back MPEG4 files; so for many employees a web browser such as UE or Chrome will be enough to view the presentation.

Alternatively Mac, Windows, and Linux users can all play exported movies using the free application VLC.
