Compress Images in PowerPoint
A PowerPoint deck gets heavy fast when every slide holds a full-size photo, which makes it slow to open and hard to email. PowerPoint has a Compress Pictures option, but compressing each image with imagetogif before you insert it gives a smaller, more predictable result. It runs in your browser.

Tips that make a difference
Compress before inserting
PowerPoint's Compress Pictures lowers embedded resolution across the deck. Doing it per image first gives more control.
Resize to the slide
Match the image to how large it appears on the slide, then compress, so you are not storing a giant photo.
Mind the total size
Ten full-size photos make a heavy deck. Compress each to keep it shareable.

Why is my PowerPoint file so big?
Full-size images are the usual cause. Compressing and resizing them before inserting cuts the file size sharply.
Is my image uploaded?
No. Compression runs in your browser, so your image never leaves your device.
