在我们继续之前，请记住，在撰写本文时，此功能仅在Microsoft PowerPoint的桌面版本上可用。^{(Microsoft PowerPoint)}未来情况可能会发生变化，用户将能够在Office Online中压缩照片，但就目前而言，就是这样。

如何压缩PowerPoint中的所有图片

请^(Make)务必按照本文中的说明进行操作，以使PowerPoint演示文稿中的图像尽可能保持最佳尺寸。

How to compress all Pictures in a PowerPoint presentation

When creating а presentation in PowerPoint, it makes sense for the images to be as small as possible because we do not want to share a document that is too large. Reducing overall file size and saving on disk space is paramount, well, at least for us.

Before we go forward, just bear in mind that this feature is only available on the desktop version of Microsoft PowerPoint at the time of writing. Things will likely change in the future and users will be able to compress photos in Office Online, but for now, this is it.

How to compress all Pictures in PowerPoint

Make sure to follow the instructions in this article in order to keep the images in your PowerPoint presentation in the best size possible.

1] Add your photos to a Slide

Before we go on ahead and compress images, users must first add a photo to their presentation if one hasn’t been added already. In order to accomplish this, folks must first click on the Insert section at the top, then from there, select Pictures and choose from the options available via the dropdown menu to include an image.

When it comes down to compressing the image or images you’ve just added, this is a simple task to accomplish. In order to get it done, you must first select the image in the slide, and right away you should see some changes made to the menu above.

It will automatically switch over to Picture Format, so the first thing to do here, is to click on the section that says Compress Pictures. A small window will appear in the middle of the Slide. Select the option you wish for the picture. They are as follows:

1. High fidelity
2. HD (330ppi)
3. Print (220ppi)
4. Web (150ppi)
5. Email (96ppi)
6. Use default resolution

Select any one option from that list, then hit the OK button to compress the image. Now, before hitting the OK button, you can choose to have the changes made affect all pictures in the presentation and to automatically delete cropped sections of all photos.

When everything is done, go on ahead and save your PowerPoint presentation.
