Compressing Pictures With today’s cameras and phones that take mega-megapixel pictures, it’s easy to end up with huge files. When this happens, you might consider using the Compress Pictures feature to bring them to a more manageable size. You should know a few things about picture compression. First is that it’s on by default.
Yes, PowerPoint automatically compresses your pictures when you save your file. It uses a target pixels-per-inch resolution of 220, which gives an adequate balance of quality versus file size for most uses. Second is that you can still use Compress Pictures to compress more. Third is that after PowerPoint has compressed your images, it won’t compress them again at a higher resolution because that would cause your pictures to look really bad.
Compress Pictures to Reduce File Size Apply picture compression according to how you intend to use your file. For example, if you need to email it, you might want to apply maximum compression. Select a picture on a slide. Ideally, use a presentation that includes a number of pictures. Click the Compress Pictures button on the Picture Tools Format tab. This opens the Compress Pictures dialog box. To apply compression to all images in the file, uncheck Apply Only to This Picture.
Uncheck Delete Cropped Areas of Pictures if you want to leave the cropped areas available. Select the target output resolution, which will depend on how you intend to use the file. Select E-mail (96 ppi) for maximum compression. Use Web (150 ppi) if you plan to post your presentation online or project it.
So for all such users who want to compress his / her PowerPoint file just have a look at this article and find out how to compress PowerPoint file in Mac. There are several ways through which you can compress a PPT file on your Macintosh computer. The latest Mac OS X operating system has built in application to compress a file.
Choose Print (220 ppi) if you intend to print. The HD option (330 ppi) is now available for high-definition displays. Some Options Aren’t Available If the picture has already been compressed, higher-resolution compression options may not be available. For example, if you’ve saved the file and left PowerPoint’s default 220 ppi compression setting selected, you won’t be able to compress the image again using 330 ppi (HD).
Many images you download from the Web will already be fairly compressed, so many of the higher-resolution compression options may not be available for them. Also, although PowerPoint will let you specify compression settings for CMYK images, they won’t actually compress at all. The option to Use Document Resolution refers to the resolution specified on the Slide Show tab in the Set Up Slide Show settings.
Usually this resolution is the same as your computer screen, unless you consciously changed it. The biggest drawback here is you must remember to do this for every file. If you’re willing to edit your registry (or know someone who’s willing to do it for you), you can turn off automatic image compression for all PowerPoint files.
To learn how, see the instructions at. (Substitute 16.0 for 12.0 in the registry key listed.) After disabling image compression this way, you’ll have to use Compress Pictures any time you want to compress the file. But at least that way you, not PowerPoint, choose when and how much it happens.
I am helping a friend get a book ready for publishing. It uses a lot of images. All of the images were scanned at 600 dpi and inserted using the Insert Picture menu on the Word 2011 application my friend is using.
I am using the latest version of Word for Mac as part of my Office 360 subscription. The problem is that while most of the images are more than the 240 dpi the publisher requested, there are about 30 that are coming in at about 100 to 140 dpi (I run a macro I found online to determine resolution). I cannot figure out why some are different than others. My friend as reduced the size of the images to increase dpi, but that only works to a point. I have been trying to find a way to turn off picture compression. I found this solution: but it doesn't apply to the Mac versions of Word (i.e., there is no 'option' link in the File menu). I'm going to try saving the file on a colleague's PC and seeing if the solution works.
But, short of that, DOES ANYONE HAVE ANY IDEA HOW TO TURN OFF PICTURE COMPRESSION ON RECENT MAC VERSIONS OF WORD? Thanks for your help.
