Frequently Asked Questions
How much smaller will my file get?
It depends on what's in the deck. Usually somewhere between 30% and 70%. If your slides are stuffed with photos pulled straight off a DSLR, you'll see the biggest drop. A text-heavy deck won't shrink as much because there's not much to squeeze.
Will my slides look worse after?
On Low and Medium, honestly, you won't notice. High is a different story. It drops image resolution pretty aggressively, so it's fine for something you're projecting or sharing on screen, but don't use it if you're printing handouts.
Is there a size limit?
50 MB per file. That covers most decks. If you're bumping up against that, your deck probably has bigger problems than file size.
Are my files safe?
Yep. Your file goes to our server, gets compressed, comes back to you, and then it's wiped within 5 minutes. We don't keep copies and we don't look at them.
Can I do a bunch of files at once?
Not right now. It's one file at a time. If you've got ten decks to compress, you'll have to run them through one by one. Sorry.
What about old .ppt files?
Only .pptx works (PowerPoint 2007 and newer). If you've got an old .ppt kicking around, open it in PowerPoint and save it as .pptx first. Takes two seconds.
Does it work on a Mac?
Yes. Mac, Windows, Linux, Chromebook, whatever. If it has a modern browser, you're good.
What's actually happening under the hood?
We unzip the .pptx (yes, a pptx is basically a zip file), find the embedded images, re-save them at a lower resolution with JPEG compression, and zip it all back up. Your text, fonts, layouts, and animations stay exactly as you left them.
