Frequently asked questions

Will my formatting change?+

No. Only embedded pictures are optimized; everything else is copied byte-for-byte.

Why is my PowerPoint so big?+

Usually because of full-resolution photos pasted from a phone or camera. Those are resized to what a slide can actually show, which often saves 70–90%.

Are my files uploaded anywhere?+

No. Everything runs inside your browser on your own device, so confidential documents never leave your computer. That also means there's no upload wait.
