您向PowerPoint中添加的信息越多，它增加的越多，主要是当您的演示文稿包含视频、音频和图像时。由于^(Due)打开演示文稿时文件大小增加，可能需要更长时间才能打开。大文件演示的另一个问题是通过电子邮件发送演示文件；它无法通过电子邮件发送，但您可以将演示文件保存到OneDrive或GoogleDrive，然后共享链接。如果您想通过电子邮件将PowerPoint演示文稿文件发送给某人，您可以压缩PowerPoint演示文稿。

减小一个或多个文件的文件大小的过程称为压缩。

压缩^(Compress)PowerPoint演示文稿中的所有图像

在本教程中，我们要减小文件大小。我们将采取的第一个过程是压缩所有图像。

打开PowerPoint演示文稿。

单击^(Click)幻灯片上的任何图像。

图片格式^{(Picture Format)}选项卡将  出现在菜单栏上；点击它。

在图片格式^{(Picture Format)}选项卡上，单击调整^(Adjust)组中的压缩图片。^{(Compress Pictures)}

将出现一个压缩图片^{(Compress Picture)}对话框。

在对话框中，您将有两个压缩选项^{(Compress Options)}：仅应用于此图片^{(Apply only to this picture )}和删除图片的裁剪区域^{(Delete cropped areas of pictures)}。

去掉压缩 选项^{(Compress Option)} 复选框 里面 的 棍子只 应用于 此 图片^{(Apply only to this picture)}.

在对话框内的解决方案部分，单击^(Resolution)电子邮件 (96 ppi) 复选框：最小化共享文档大小^{(E-Mail (96 ppi): minimize document size for sharing)}。

然后单击确定^(OK)。

将视频链接^(Link)到 PowerPoint 演示文稿

如果我们有一个很大的视频文件，这主要是PowerPoint演示文件很大的原因。

要解决此问题，我们必须在演示文稿中使用指向视频的链接。

删除^(Delete)演示文稿中的视频。

单击插入^(Insert)选项卡，然后单击媒体^{(Media )}组中的视频^(Video)按钮。

在下拉列表中，单击此设备^{(This Device)}。

将打开一个插入视频^{(Insert Video)}对话框。

在对话框中，选择视频文件，单击插入^(Insert)列表框，然后选择链接到文件^{(Link to File)}。

现在我们要插入视频的URL。

应该插入一个URL，因为当您通过电子邮件发送演示文稿时，视频不会显示。毕竟，它在您的 PC 上，但如果您有YouTube频道，则可以将视频上传到该频道并提供链接，以便该人可以看到该视频。

您不必公开上传视频；你应该私下上传。

在插入^{(Insert )}选项卡上，单击媒体^(Media)组中的视频^{(Video )}按钮。

在下拉列表中，单击在线视频^{(Online Video)}。

将出现一个对话框供您输入URL。

输入URL，例如，在您的YouTube频道上发布的视频。

单击插入^(insert)。

将演示文件另存为原始文件的新文件。

检查PowerPoint演示文稿的文件大小以查看大小是否减小。

我们希望本教程可以帮助您了解如何压缩PowerPoint文件大小；如果您对本教程有任何疑问，请在评论中告诉我们。

Click the Insert tab and click the Video button in the Media group.

In the drop-down list, click This Device.

An Insert Video dialog box will open.

Inside the dialog box, select the video file, click the Insert list box, and select Link to File.

You do not have to upload the video publicly; you should upload it privately.

On the Insert tab, click the Video button in the Media group.

In the drop-down list, click Online Video.
