I’ve got 27 photos totalling 14 MB. If put them in a Power Point file will the PPT file size be 14MB + or will PPT reduce the size of each picture making the PPT file size less that the 14MB of photos?
Thanks.
The file size will include the total size of all the pictures. The reason being that PowerPoint stores the entire image, and then you can resize that as you wish. If you shrink the picture in PowerPoint, the actual picture quality is kept so that if you want to, you can make the picture bigger again without losing any image quality.
If you need a low file size, you’d want to actually shrink the pictures themselves before putting them into PowerPoint.
You can compress images after you insert them onto slides. The simplest thing to do is do all your inserting, then compress everything all at once.
One feature a lot of folks miss is the option to delete the cropped-out portion of cropped images, which can help a lot.
In PP 2007, it’s on the “Picture Tools > Format” tab, “Compress Pictures.”
