    How to Easily Bulk Resize Images in Mac OS

    The biggest trouble you face with images you store on your device is batch editing. Here, you may want to batch rename or resize images or want to apply other filters to make your images more appealing. In general practice, it consumes a lot of time & efforts to do such editing in batches. Here, we have tried to help you deal with this issue on your Mac. In this article, you will find the ways how you can batch resize your images on your Mac using a built-in utility or using an advanced batch image editing tool like Tweak Photos.

     

    Use Built-In App

    To begin with, you can use the built-in Preview app on your Mac to resize images effortlessly. Here, this app comes built-in on all Mac versions and helps you manage your photo collection in a few simple steps. You can use this app to resize images in various resolutions and sizes as per your requirement in a group. Further, you can save output file as a new file with a new resolution or you can save it as an original file (with changes) on your system.

    To start using this app, launch Preview app from Applications/folder. This app is a default image editor for Mac and it can be opened by simply opening any picture. Once you have launched the Preview app, follow below-mentioned steps.

    Go to image folder and select all those images that you want to reside in the Finder and open them within the Preview app.

    Here, choose all these pictures that you wish to batch resize from the left-side thumbnail drawer or simply press Command + A keys to select them all.

    Go to menu and select Tools < Adjust Size.

    Once you are on Image Dimensions window, select the image size units (pixels, cm, mm, inches, or points) that you wish to use to resize images next to Width and Height fields.

    Note: If you have selected multiple size images then we suggest you use Percent as it is relative to the original image size. Using other options may cause you trouble with the desired result.

    You can select “Scale Proportionally” option, in case you want to adjust Hight or Width automatically when you enter one value. Once you enable this feature, it will display a lock icon next to Width and Height boxes.

    Now navigate to the folder where you wish to save newly resized images files. Here, tap on Options < Format and select the desired format (for example JPEG, PNG etc.) and tap on Choose button.
