![]() One thing to remember is that having your input file path the same as the output file path is generally a Bad Thing. Note that the word ‘sips’ is followed by some parameters (in our case, “-s format png”), then the path to the source file, then we used –out to tell sips where to put the resulting file. The sips command we just created is a fairly typical one. Now we have a full sips command, so hit return to execute the command and a file should be created at the location you specified with the –out parameter. Alternatively, I could have used something like “~/Desktop/file.png” to save the file to my desktop, or I could have used any other path that suits my purpose. Note that for the output file path, I just copied and pasted the input file path and changed the extension to “png”. Sips -s format png /path/to/your/file.jpg -out /path/to/your/file.png We can do this by adding –out followed by the location of the file we want to be created, so add that into your Terminal like this: All we need to do now is to tell it where to put the resulting file. That tells sips that we want to change the format of the image we dropped to a png. Sips -s format png /path/to/your/file.jpg You should now have something in your Terminal that looks like this: …next, drag any image file other than a png file into the Terminal. It’s just an app that lets us work on the command line and you’ll find it in /Applications/Utilities. In this article I’m going to show you some simple uses of sips, and how to roll them up into a handy Automator workflow.įirst, lets fire up the Terminal. jpeg, tiffs, png etc) without ever having to fire up Photoshop. ![]() ![]() You can use it to do all sorts of interesting things to raster images (eg. Luckily, every Mac has a powerful system lurking under the hood called ‘sips’ (Scriptable Image Processing System). Computers were supposed to relieve us of this kind of drudgery, right? It can also be surprisingly error prone as your mind drifts off halfway through to think about what you’re up to at the weekend. If you’ve ever had to convert a few hundred images from tiff to png, create thumbnails of them you’ll know how time consuming and boring it can be.
