OS X’s Preview is the little image viewer that keeps on giving. Preview is so feature-rich that there’s usually little reason to install another image viewer. It can even resize a large batch of images at once.

OS X的Preview是不断提供的小型图像查看器。 预览功能如此丰富，以至于通常没有理由安装另一个图像查看器。 它甚至可以一次调整大量图像的大小。

Resizing in batches makes short work of what would normally be a tedious and time-consuming process, assuming you’re resizing all your images to the same dimensions.

假定您将所有图像调整为相同的尺寸，则批量调整大小可以简化通常很繁琐且耗时的过程。

To perform a batch resize, you can either open Preview from the Dock and File > Open your images…

要执行批量调整大小，您可以从Dock中打开预览，然后选择文件>打开图像…

…or, you can select a bunch of images in the Finder, right-click on them, and then choose Open With > Preview.

…或者，您可以在Finder中选择一堆图像，右键单击它们，然后选择“打开方式”>“预览”。

All of your images should open in Preview’s left sidebar.

您所有的图像都应在“预览”的左侧栏中打开。

Now, you could go through each image, click on the “Tools” menu, and select “Image Size” to resize them one by one. But we have a better way. First, select all the images by clicking on the “Edit” menu and then “Select All”, or using the keyboard combination Command+A.

现在，您可以浏览每张图像，单击“工具”菜单，然后选择“图像大小”以逐一调整它们的大小。 但是我们有更好的方法。 首先，通过单击“编辑”菜单，然后单击“全选”，或使用组合键Command + A选择所有图像。

Now you will see that all your images are highlighted, which means they’re selected.

现在，您将看到所有图像都突出显示，这意味着它们已被选中。

Now, click on the “Tools” menu and select “Adjust Size…”.

现在，单击“工具”菜单，然后选择“调整大小…”。

Since our images are varying sizes, the width and height values will tell us they have “Multiple Values” but we know that our width needs to be 325 pixels for all of them. So, we enter this number and then click “OK”.

由于我们的图片大小各不相同，因此宽度和高度值会告诉我们它们具有“多个值”，但我们知道所有图片的宽度都必须为325像素。 因此，我们输入此数字，然后单击“确定”。

We’re not done, however. In order to make these values stick, we need to save our images. Again, we don’t have to save each one separately. Since all our images are selected, we can go ahead and click on the “File” menu and choose “Save”, or use the keyboard shortcut Command+S.

但是，我们还没有完成。 为了使这些值保持不变，我们需要保存图像。 同样，我们不必分别保存每个。 由于已选择所有图像，因此我们可以继续并单击“文件”菜单，然后选择“保存”，或使用键盘快捷键Command + S。

Once saved, you will notice that the “Edited” notation in the titlebar will disappear.

保存后，您会注意到标题栏中的“已编辑”符号将消失。

You can use this trick with any other changes you make to multiple images in Preview, so you can rotate, adjust the color, and more. But for us, resizing is bar none the most useful option for our purposes. Undoubtedly this will be a big time saver for many folks who use a Mac and the Preview app.

您可以将此技巧与对“预览”中的多个图像所做的任何其他更改一起使用，以便旋转，调整颜色等。 但是对于我们来说，调整大小绝不是实现我们目的的最有用的选择。 无疑，对于许多使用Mac和Preview应用程序的人来说，这将节省大量时间。
