You can change the existing presets or add a new one. If you want to set up the Image resizer so it's always set to use specific sizes, you can customize the size presets it offers.Launch PowerToys and switch to the Image Resizer tab.Download the latest version of PowerToys, available on GitHub, and install it.PowerToys actually has a lot more tools than the image resizer, but that's what we're focusing on for now. My personal favorite is PowerToys, which is also published by Microsoft and developed in collaboration with the open-source community. If you want to resize multiple images at once, there are some tools you can download to help you out with that. The two methods above work well if you just want to resize an image or two, but if you have a folder with a ton of large images, that's going to get tiring after a while. Luckily, Preview can also handle cropping images – but that is a story for another tutorial.This is another easy method for resizing images, and it's the one I personally used most frequently for a long time. You will probably find that resizing is a good place to start – but you might actually want to crop your image first, before you resize, in order to get the dimensions just right. Make copies of a few photos that you have on your computer and practice changing the dimensions. My suggestion to you is play around with it. But it does take a little trial and error. Knowing how to resize images on a Mac using Preview will make blogging so much easier for you.Īs you can see, it is pretty simple. The ShortPixel plugin will compress all of these different sizes behind the scenes so you don’t even have to think about it. You see, WordPress creates several different image sizes from the one image that you upload (your theme will use thumbnails, featured image sizes, etc). I used to try to compress images in Preview on a Mac but this was an inefficient and tedious process. This is easily done with a plugin called ShortPixel.

However, if you are uploading images to a blog or website – you should also compress your images to make the file size even smaller. This process reduces the image file size somewhat. In this post I am talking about how to resize the actual dimensions of your photo. I leave scaling and resampling checked and hit Ok. However, if you plan to print your images at large sizes – it is best to keep the resolution number high if it comes up that way. I keep mine at 72 which is a good size for the web. It is a best practice to resize your image to a reasonable size for the web before uploading it to your blog. Generally WordPress will automatically resize a large image to fit your template BUT large image sizes will slow your site down – even thought the photos look ok online.
