Resizing Photos Easily Using Mac’s Automator and Services

Services can resize photos

If you’re like me, you probably have to resize photo files a lot. I’m constantly adjusting picture sizes to share with others, add to the blog, or post on Twitter.

There are apps that resize photos – tons of them – but I’ve found the easiest way is to do it with a right click right in the macOS Finder. I have this little Automator script set up where I can right-click on a photo file, go to Services, and resize a photo to either 1000 or 2000 pixels wide (above).

Often, I’ll duplicate the photo file and then resize the copy to preserve the original file’s dimensions.

Preview does this. Little apps here and there does this. But I like simply clicking and picking my size, and letting the operating system do the rest. You can do this easily within Automator (a great, time-saving little bundle of joy, by the way), but I’m making my two little Services available as a download.

Download the 1000 pixel version and the 2000 pixel version as a ZIP file. For installation, Brett Terpstra has a how-to on adding system Services in macOS (under “Move the File”).
