Pavel Jelic If you are a macOS Big Sur user and at the same time work with a large number of photos or images every day, you have probably already noticed an error in the Preview application. This bug has been around since about the eighth beta of macOS Big Sur and unfortunately has not yet been fixed, despite being reported several times. If you're a Preview user, you probably already know what I'm talking about. For other users – unfortunately, it is currently not possible to optimize photos and images in macOS Big Sur within the aforementioned Preview.

Flying around the world with Apple For me personally, the ability to natively optimize images and photos on a Mac is very important. When writing articles, I need to create galleries that contain photos that are optimized for the web. In older versions of macOS, it was simply enough to have the images exported, and then use the slider to choose the approximate resulting size. However, currently the slider does not in any way determine how large the optimized photo will be and there is absolutely no change. After exporting these images, you will find that in the final they are exactly the same size as before export, which is quite a huge problem. Unfortunately, there is no way around this error, and you have to download an application to optimize it.
There are quite a few such applications that can be used to optimize images on the Internet. But for most of us, it is important that such an application is as simple and fast as possible. During the last few days, I have already tried several such applications, and the one with the name was the most convenient for me ImageOptim, which is available for free. After launch, you will see a simple interface into which you can simply drag and drop the photos to be optimized. You don't need to do anything else - the optimization is done automatically and the percentage of space saved is displayed. As for setting the "strength" of the optimization, just go to Settings, where you can set everything you need for each format. So ImageOptim is currently a great alternative to Preview for photo optimization in macOS Big Sur.
