While enlarging a photo, you are breaking each pixel into certain subpixels. Clicking on the drop down menu at the bottom of the dialog will reveal the many ways in which you can ‘resample’ your image. The reason Luminar is better than most photo editors on your Mac for enlarging photos, however, is the number of resampling options you have while changing the Image Size. If you check the ‘ Constrain Proportions’ box then Luminar will automatically adjust the height of the image according to the original aspect ratio. In order to make your photos larger in Luminar, open the Image Size dialog and enter the desired Width and Height that you want your image to be. You can essentially drag and increase the photo sizes in multiple image editors, but Luminar gives you more control over the output quality of your enlarged photos. The best way to enlarge your photos on a Mac is to use Luminar. These programs give you a little more control over your images, but essentially their crop tools work the same way as that of Preview’s. You can also use more advanced programs like Apple Photos or Luminar to crop your images. Simply open the image in Preview, go to Tools and select the Crop option to make your image smaller.Ĭropping not only cuts into your image but also makes the overall size smaller. The easiest way to do it is to use Mac’s own Preview app. Cropping an image can be done with almost every image editing program you have on you Mac. The quickest way to resize an image, if you need to make it smaller, is to crop it. Let’s take a look at both ways to resize an image on a Mac computer. This is important if you like to post your photos online, as some social media platforms don’t allow images with huge file sizes to be uploaded. In that case, you need to know how to change the resolution of your image to make it smaller. But maybe you simply need to change the file size of your image, and not necessarily the aspect ratio or field of view that it has. In order to physically resize your photo, you can either crop into it or enlarge it. Resizing images can mean more than one things. You may feel the need to resort to post processing even if you wish to accomplish a seemingly simple task like resizing your image. It doesn’t have to do with just color correcting images and fixing exposure. No matter how much time you spend taking a photo or how carefully you compose it, you still may have to tweak it a little in post.

Post processing is pretty much an essential part of photography.
