PPT Optim is a free simple lightweight Powerpoint add-in that reduces the file size of your Powerpoint presentation.
It optimizes the images included in your presentation, without decreasing their quality. The optimization is more performant than the built-in “Image compression” of Powerpoint.
It can also convert embedded objects, such as charts, to images in order to reduce the size even more.
We’ve tested the add-in on many presentations. The add-on reduce the file size up to 80%. The average file size reduction is 50%.
This is a beta version. Some improvements are planned, such as improved file reduction and improved process speed.
This add-in is a freeware.
