When you press Return, sips will convert your image file-and it's really fast, even on larger files. Type this, then press Return: sips -s format jpeg -s formatOptions 80 "Beach party.tiff" -out "Beach party.jpg".(Alternatively, you can use this tip to directly open the selected Finder folder in Terminal.) Type cd, then press the Space Bar, then drag in the folder that contains the image(s) to be converted.Open Terminal, in Applications > Utilities.
Assume you have an image named Beach party.tiff that you'd like to convert into a smaller JPEG, but with a relatively high quality setting. (The following is written for Terminal neophytes, so apologies for any over-explaining). You can also use sips to resize images, rotate images, and more.īasic usage of sips is straightforward. sips can modify one file, or any number of files, converting from one format to another. Yes, it requires using Terminal, but it's quite easy to use. You could also use Automator, which has some good image conversion abilities, but can't (for example) specify the quality of a JPEG conversion.īut the best way I've ever found is to use a tool that's been included with every copy of macOS since the release of Mac OS X 10.3 (Panther) in October of 2003: A command line tool called sips. If you search the Mac App Store, there are probably 300 apps that will let you do this many are probably free. Quite often, I find myself with a number of images (screenshots, typically) that I'll want to convert from one format to another.
