Join David Blatner for an in-depth discussion in this video Adjusting image compression, part of InDesign Insider Training: Print PDFs.
…One of the most common questions I hear is why is my PDF so large?…And the answer is usually right here in…the compression pane of the export PDF dialogue box.…Now I know this looks overwhelming and confusing, but the good news…is that it's actually pretty straightforward once you see how it works.…The whole point of the compression pane is to help you make your PDF smaller.…Like 1 megabyte instead of 20 megabytes.…And generally the way you do that is to compress your images, like photographs.…
There are two ways to compress your images and make them take less space in the PDF.…First, you could lower the image resolution.…Use fewer pixels.…For example, you don't need your photographs to…have a resolution of 600 pixels per inch.…It's just way too much data.…Even for printing on a high-end digital press.…So InDesign can lower the resolution for you when you export the PDF…so you don't need to go back to Photoshop and do it there.…That's called downsampling.…You can see the various downsampling options here.…

Q: Why can't I open the exercise files?
A: If you cannot open the files, try the IDML file, as David explains in the third movie of the course.
