Best Free Image Compressor for Mac : ImageOptim

When ever we talk about publishing images for web, one of the most important thing is to keep it light weight. Even in our guide to image optimisation for SEO, Anasshad emphasised on compressing your images to make your web-page load faster. When you are publishing 1-2 images in a blog post, you might ignore image compression, but when you are someone who understand the importance of images in a blog post or is a photographer, you might face the issue of slow loading of pages due to multiple images. Earlier I have talked about Smush.it WordPress plugin which is one fantastic free plugin to compress your images without doing anything, and if you are not so fond of plugin, here are 3 softwares for Windows to compress and resize the images. Today I will be extending the topic by sharing about ImageOptim, which is one software I’m using for almost an year now and it’s a great tool for Mac OS users to compress images.

ImageOptim : Optimize Images for Web on Mac

ImageOptim is a lossless image compression tool for mac, that means it doesn’t affect the quality of image while reducing the size. ImageOptim supports multiple image formats like png, JPEG, .gip animations. The best part about this image compressor is; it’s open source and completely free. It integrates some of the best free image optimisation tools like PNGout, Zopfil, Jpegoptim to name a few.

Using Imageoptim is pretty straight forward and if you are on Mac, you can try this tool right now by download it from official page over here. Once you have downloaded and opened Imageoptim software, all you need to do is; drag and drop the images that you want to compress. Here is a screenshot for the same:

By default this app is configured to strip important meta data like Geolocation of image, EXIF and so on. If you wish to retain those metadata; you can go to preference and uncheck the options. Here is a screenshot of imageoptim preference page:

Overall Imageoptim is one of the best free app I have found for compressing images. If you are someone who is blogging on a Mac system, this is one must have blogging tool for making your images web-ready. As I mentioned in earlier articles, I use Snag It for Mac to take screenshots and if you missed it, you can check this tutorial over here. What I usually do is, take screenshot using Snagit, resize the images and then use ImageOptim to compress the image. This ensures that images which I publish on my blog post are optimised for maximum performance. You can always go one step further by incorporating Content delivery network like MaxCDN.

There are few more image compressors which you can use on your Mac like TinyPNG, JpegMini but the problem with them is they use lossy compression technology, that will reduce the image quality.

    Hi there Harsh , thanks for sharing the knowledge again. Is there a windows binary as in a msi or exe for image optim or is it just for mac. I believe this should work on linux for sure.
