Pixelmator Pro 2.3 went live on the Mac App Store on Tuesday, and the latest major update to the popular image editing app brings a smart new automatic background removal feature, automatic subject selection, new Select and Mask tools, and more.


In a blog post announcing the update, Pixelmator's developers say that it's now possible for users to "magically" remove the background from any image with just a click. The new feature is based on machine learning models that can find a subject in almost any image and automatically strip out the background, and it's also available in Finder as a built-in Quick Action.

In addition to the background eraser feature, a new AI-powered Decontaminate Colors feature can remove traces of the old background from the edges of objects left behind, allowing them to blend seamlessly with any new background. Decontaminate Colors can be applied manually in any layer, even on ones that have been cut out in other apps.


Building on the same set of machine learning algorithms is Automatic Subject Selection, which allows users to make a selection of the subject of any image with just a click. Meanwhile, a new Select and Mask tool makes it easier to select difficult areas of subjects like hair, fur, and other objects with complex edges.

The Smart Refine feature has also been redesigned to enhance selection accuracy, and a new Refine Edge Brush lets users brush over particularly tricky edges to get the selection they want.

These new features are powered by ML algorithms that are integrated into Pixelmator Pro using Core ML, which makes them "absolutely fly" on the latest M1-powered devices thanks to their overall speed and the Apple Neural Engine, according to the developers. For example, background removal takes around 2-5 seconds on M1 devices and up to 30 seconds on Intel devices for an average image.


The update includes some smaller changes, like the ability to specify custom export sizes and scales in the Export dialog. More details are available in the release notes. Version 2.3 is free for existing Pixelmator Pro users, and there's currently a 50% discount off the app price (usually $39.99) in the Mac App Store.

I was so excited when I saw the Monterey wallpaper... When is Universal Control coming? I was so incredibly excited for it.

I'm asking myself the same thing.
It's basically the price of 1-2 months of Photoshop, except that you own it and you have it forever.

Incredible app from top-tier developer.

Nothing better than true native Mac apps. it’s amazing Apple is allowing halfass iOS apps to pollute the Mac.

I use Affinity Photo mainly because Pixelmator Pro is limited. But have it is a very nice addition. I often use ML Resolution to quickly clean up images from online source when I want to use them for Keynote presentation and it works amazingly.

Monitor resolutions are constantly increasing. However, Pixelmator continues to use tiny, microscopic icons and text in the toolbars and tool palettes. Instead of distinguishing icons by sight, I have to resort to remembering them by position. The numerical displays for coordinates, zoom level, RGB values in the main window, and slider values in tool palettes are also microscopic. The tiny text and icons make Pixelmator frustrating to use on high resolution monitors. BBEdit is just as bad, so it’s not just graphic design applications that do this. After multiple emails to BBEdit and Pixelmator, there is still no change. Why do so many of these “professional” applications like to use tiny, microscopic icons and text in toolbars and tool palettes? And why do the developers of these applications continually refuse to update their interfaces to work better with high resolution monitors?

PSD file support?

Hmm, let me think of one case: You don't use Mac?
This is MacRumors. We're posting in a forum thread for an app that is Mac-specific. Why would Windows even be a part of the question, here?

I'd recommend "Affinity Photo" instead if you need anything similar to Photoshop
ah, Affinity, that was a good and in-depth program,
just could not get used to the tool settings and searching for the select tool or erase tool
no matter what i needed to perform on affinity i just could not get into that rhythm.
Krita is better friendly wise, but crashes and doe snot have the preview image.

thanks for the tip tho!
