Reduce the file size of a PowerPoint presentation

The big file size of a PowerPoint presentation will take a longer time to open and run. Also it will ask for more computer source. What's more important, it makes the presentation not delivery-friendly. Then how to reduce the file size? There are some solutions.

>>>Optimize the multimedia content in PowerPoint presentation

1. Change the resolution of Images, graphics, and pictures in PowerPoint

The resolution should not more than 72dpi because nearly all the TV screen, monitor or projector can not play images up to 72dpi. Images with high resolution are good for printing but never for the file size. So check the images, graphics and pictures and edit them with an image editor. 2. Change the definition of audio in PowerPoint Transform the music or other audio in PowerPoint from stereo to mono, from 44khz to 22khz. In most cases, audio is recorded in high definition 16 bit 44khz stereo. The fact is that the differences between stereo and mono is so much small to the human ear. In a conference hall or through a PC speaker the differences may not be recognized. 3. Change the compression format of video in PowerPoint Video is often recorded and captured in the compression format MPEG-2 with 720 x 568 pixels. It is good for full screen play. However, when embedded to a presentation, it will increase the file size dramatically. You can choose video in MPEG 1 to embed to your PowerPoint presentation. What is more, reduce the video from 512 x 384 to 720 x 568 will also low down the overall file size.

>>>Convert the PowerPoint presentation to another format: ppt/pps ->flash As the theory goes, if you convert your PowerPoint presentation to flash, the file size will be reduced by 90%. The only thing you need is a conversion software. There is an example to make it understood easily.
