![]() Which means that my Keyboard Maestro macro for taking screenshots and uploading them to the blog’s server can reduce their file size during the process. This is all very well and good, but I wouldn’t think as highly of ImageOptim if it weren’t for one very useful feature: it can be run as a command line program. You’ll note that I don’t have my images run through Zopfli or PNGOUT, as these programs run slower than the others, and I don’t think the extra time is worth slight extra reduction in file size. The image file is overwritten with that optimized version and you’re told how much smaller the file became. The given image is run through each of the checked programs appropriate for its file type, and the one that provides the smallest file is selected. You can see and choose the programs in either the Preferences or the Tools menu. Generally, I get 25–40% smaller files after running them through ImageOptim.įundamentally, ImageOptim is a front end for a set of open source image optimization programs. And it can do this for PNGs, which is the format I use for the screenshots I post here. what ImageOptim really excels at is reducing the file size without changing the image quality. I’m sure you already know that a JPEG’s file size can be reduced by lowering its “quality.” ImageOptim can do this kind of optimization, but so can lots of apps. What ImageOptim leaves you with is an image that takes up less space on your disk it doesn’t take up less space on your screen. It doesn’t resize an image in the sense of changing its width or height in pixels. 1 One of Stephen’s picks is ImageOptim (discussion starts at 1:00:50), an app I use all the time but haven’t talked about here.Īs suggested by its name, ImageOptim optimizes images by reducing their file size. As usual, this one has a good mix of apps that are new to me and those I already know about. New images are all images added since last manual optimization run, you probably will not need to use this feature if you have optimization on file upload enabled.Yesterday, I listened to the most recent Mac Power Users episode, “20 Mac Apps Under $20.” Although MPU is probably best known for its deep dive episodes, I always like these more rapid-fire discussions. ![]() Go to Admin > Config > Media > Image Optim (admin/config/media/imageoptim) and run "Optimize all images" or "Optimize new images" in manual optimization fieldset.How to scan and optimize image files manually If you apply multiple effects set the Image Optimizer effect the last one, because if the image is re-saved using another toolkit you can lose the image optimization.

Images are send to ImageOptim web service using an HTTP Request and then donwloaded and replaced with an optimize version. You’ll need to obtain an API key/username from ImageOptim.
