PowerPoint makes pictures blurry or unsharp, loses GIF animation

Problem

When you save presentations in PowerPoint 2007/2010/2011(Mac)/2013 then open them again in any version, the pictures in your presentation are blurry or less sharp than when you first inserted them.

In some cases, your animated GIFs may lose their animation.

The same thing happens in Word 2007/2010/2013 and the fix is the same.

Solution

PowerPoint 2007/2010/2013 have an option to automatically compress images when you save the presentation. That's a good thing.

This option is turned on by default. And that can be a bad thing. Programs should never, ever throw away a user's data without asking for permission first, but that's exactly what PowerPoint does.

Worse, when PowerPoint compresses an animated GIF, the animations are lost.

And even worse, it's hard to find the dialog box where you can turn this "feature" off.

And ... are we having fun yet? ... turning compression off applies only to the current presentation. You have to change the option for every presentation you work on.

If you've already inserted any pictures, be sure to turn compression of BEFORE you save your presentation. Otherwise it'll be too late. Your pictures will be compressed when you save. Here's how:

To turn compression off (but only for the current presentation) in PowerPoint 2007:

To turn compression off (but only for the current presentation) in PowerPoint 2010 or later:

A more thorough solution

To really fix the problem, you'll need to edit the registry. The usual cautions apply: back up your PC first, be very careful, wash behind your ears ...

Now, by default, PowerPoint does not compress pictures. If we want to enable compression, go back to the same registry key and change the value from 0 to 1.

Or if you use Mac PowerPoint 2011

Instead of modifying the registry as above, you can modfy the Mac equivalent, the PowerPoint prefs file.

Now, by default, PowerPoint does not compress pictures. If we want to enable compression, go back to the same part of the plist file and change the value from 0 to 1.

Thanks to Marta Portela Maseda [Office MVP] for this tip, originally published on Fermu's Website. If you don't feel good about editing the registry, visit this site and click the text "reg file" and download the provided reg file. Doubleclick the reg file to make the needed registry edits automatically.

Here's the official Microsoft word on this problem
