How much smaller will it be?

Photo-heavy decks often shrink by 60–90%. Decks without pictures are already small.

Do videos get compressed?

Videos inside a deck aren't changed; only pictures are.

Why decks get huge — and how to shrink them

A 100 MB deck is almost always full-size photos and screenshots on slides that show them at a fraction of that size. This PowerPoint compressor rebuilds the .pptx with every picture scaled to a sensible size and saved again with good quality, then packs the file at the highest compression. Choose Light for printing, Balanced for screens (recommended) or Strong for strict email and upload limits. Text, layouts, charts, transitions, animations and speaker notes don't change, and the new size shows before you download.
