    这么做会打开演示文稿窗口顶部的 格式 选项卡。
    • 如果你还没有打开演示文稿文件，请先双击文件，来打开它。
    • 双击文件中的任意一张图片，都能打开“格式”选项卡。

小提示

  • 相比于其它图片格式，使用JPEG的文件格式能大大缩减演示文稿的文件大小。
  • 在做PPT时，相比于用上传的图片作为演示文稿的背景，使用默认的白色背景能让整个文件的大小变得更小。
  • 如果你的演示文稿文件无法缩减到可以通过电子邮件来发送的大小，那么你可以将它上传到云端服务器（如谷歌硬盘等），然后用链接来取代文件，来发送电子邮件。收件人收到邮件后，可以点击链接进入云端服务器，并从谷歌硬盘上直接下载文件。

警告

  • 降低演示文稿中的图片质量，能从很大程度上缩减整个演示文稿文件的大小。这种缩减量是肉眼可见的。
