Best Free Image Compressor for Mac : ImageOptim

Whenever I talk about publishing images on your blog, one of the most important things is to keep it lightweight.

Even in our guide to image optimization for SEO, Anasshad emphasized on compressing your images to make your webpage load faster.

When you are publishing 1-2 images in a blog post, you might ignore image compression, but when you are someone who understands 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 Shortpixel that is one fantastic free plugin to compress your images without doing anything, and if you are not so fond of the plugin, here are three software 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 a year now and it’s a great tool for Mac OS users to compress images.

ImageOptim: Optimize Images for The web on Mac

ImageOptim is a lossless image compression tool for Mac, which means it doesn’t affect the quality of the 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 optimization 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 downloading it from the 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 metadata like Geolocation of the 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 apps 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 could check this tutorial over here.

What I usually do is, take the screenshot using Snagit, resize the images, and then use ImageOptim to compress the image.

This ensures that images that I publish on my blog post are optimized for maximum performance.

You can always go one step further by incorporating Content delivery networks like MaxCDN.

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