OSX Tip: 2 Using preview to resize images

Like the previous post (link) we discussed how powerful Preview is in OSX. In todays tip we will resize images using Preview. Preview has become a very powerful tool it allows you to resize images, crop, annotate, remove backgrounds etc. As you find more and more of these useful features of Preview you will find yourself opening tools like Photoshop less and less. Lets take a look at resizing images in Preview.

To get started double click on the image that you want to resize. (If you have changed the default program to open images in OSX than you may have to open Preview first and click “File” and than “Open”)

Once the image is open you should see a toolbar option labeled “Tools”. In this drop down there is an option that says “Adjust Size”. Click on that.

A pop-up will come up with options for width and height. You can enter a dimension into the box and click ok
(if you want to do custom sizes make sure that you uncheck the box that says “scale proportionally”)

 

After you click ok, we need to save the image. If you want to save it as it is click file and than select “Save a version”. If you want to change the format of the image or create a new version of the image, click file and export.

After you click export, you can save the image as several different formats such as jpeg, png, tiff, pdf, etc. You can also change the quality of the image. This would be valuable if you were attaching images to an email or posted to a website. After you make your selection hit save.

Thats all there is to it! As always if you have any questions or need help feel free to comment or email me at tj at tjhouston.com
