How to Resize Images on Mac
If you're using a Mac, things are actually much simpler because the only tools you need are built directly into macOS. Apple's operating system comes with an app called Preview that lets you resize images individually and in batches.
One thing to note before doing this is that the previews will always replace the original image files when you resize them. If you want to keep the original files, copy them first, then resize the copies and keep the original images intact.
If you want to resize an individual image, do the following:
- In Finder, open the image you want to resize. If Preview is not your default for opening images, right-click the image file and select Open with and select Preview Application.
- With the preview open, click the Tools option in the top menu bar and select Resize.
- You will see a window to select the target size of the image. There are some presets available, but you can also choose custom sizes. You can resize it as a percentage of the original resolution, or use the drop-down menu to switch to absolute values. If you prefer this method, you can also choose the pixel density of the final image.
- Click OK and your image will be saved at the new resolution.
If you want to batch resize images, the process is similar, but you need to pay attention to a few things. First, select all the images you want in Finder and open them using Preview. Then, in Preview, make sure you select the thumbnails of all images you want to resize before using the Resize option.
