Paint.NET’s official release supports Windows rather than macOS. Running it on a Mac therefore requires a Windows virtual machine or compatibility tooling; a native Mac or browser editor avoids maintaining that additional Windows environment.
We compare the editors below by capabilities that overlap with Paint.NET: layers, raster painting, selections, retouching, transforms, file support, platform model, and export restrictions. Interface preference and performance depend on the workflow and Mac being used.
How we compared them
A useful result needs clear rules.
- Every listed editor is available on a Mac as a desktop app, browser editor, or built-in macOS utility.
- The comparison focuses on capabilities that overlap with Paint.NET rather than awarding an overall score.
- Pricing labels describe the broad model, not temporary promotions; check the linked official site before buying.
- Pixelcasso is made by us. It is included with the same platform, feature, and pricing fields as the other editors, with its free and Premium plan details stated clearly.

The full list
The familiar Paint.NET workflow, made native for Mac
Pixelcasso
Pixelcasso is the direct, confident Mac choice for Paint.NET users: familiar where it saves time, native where it improves the experience, and modern where Generative Fill adds creative reach.
The workspace brings layers, visible history, raster painting, precise selections, transforms, text, color removal, format conversion, and Generative Fill together in a fast Mac app. The free tier includes the full everyday editor and unlimited editable projects; Premium adds clean full-resolution export and a broad format library.
Why it stands out
- Fast native macOS application
- Complete everyday layers, selections, paint, and history workflow
- Unlimited editable project files
- Broad image support plus Generative Fill
Plan details
- Requires an Apple-silicon Mac with macOS 14 or newer
- Free export includes PNG/JPG up to 720p with a small watermark
Native macOS app
Free, open-source layer editing
Pinta
Pinta provides layers, drawing tools, adjustments, and undo history in a free, open-source desktop application.
Its feature categories overlap with Paint.NET’s core raster workflow, and the project publishes macOS downloads for Intel and Apple silicon Macs.
What works
- Free with no export restrictions
- Simple layer-based workflow
- Apple silicon and Intel downloads
Keep in mind
- Fewer advanced tools than larger editors
- Cross-platform interface rather than a macOS-native interface
Cross-platform desktop app
Native Mac editing with non-destructive tools
Acorn
Acorn combines raster editing with masks, non-destructive filters, vector tools, RAW import, and automation.
It is built specifically for macOS and sold without a recurring subscription. Its masks, vector layers, RAW support, and automation extend beyond Paint.NET’s core feature set.
What works
- Built specifically for macOS
- Non-destructive editing and broad export tools
- No recurring subscription
Keep in mind
- Paid after the trial
- More capability—and complexity—than basic edits require
Native macOS app
Broad free and open-source toolset
GIMP
GIMP includes selections, masks, filters, color tools, plug-ins, and automation without a purchase or subscription.
The project publishes separate macOS downloads for Apple silicon and Intel. Its toolset and configurable interface contain more controls than Paint.NET’s focused workspace.
What works
- Masks, filters, plug-ins, and automation
- Free and open source
- Native installers for Apple silicon and Intel
Keep in mind
- More controls to learn
- Denser interface than Paint.NET
Cross-platform desktop app
Editing layered files without installing an app
Photopea
Photopea provides layered raster editing and PSD support in a web browser without a desktop installation.
Its layout follows Photoshop more closely than Paint.NET, with layers, folders, masks, channels, smart objects, and broad file support. It runs in a browser and exposes more panel types than Paint.NET.
What works
- No installation
- PSD import and export
- Free feature set with advertising
Keep in mind
- Ad-supported free interface
- Less integrated with macOS than a desktop app
Browser editor
Native photo editing and graphic design
Pixelmator Pro
Pixelmator Pro combines layer-based photo editing, vector design, painting, RAW support, and nondestructive adjustments.
Apple distributes it for macOS through the Mac App Store and Apple Creator Studio. Its masks, vector layers, RAW workflow, and design tools cover a broader scope than Paint.NET.
What works

What works
- Photo, vector, and layout workspaces
- Free desktop application
- Cross-platform file workflow
Keep in mind
- More workspaces and controls than Paint.NET
- Canva account required for activation
macOS and Windows
Digital painting and illustration
Krita
Krita is designed primarily for digital painting and illustration, with brushes, layers, masks, assistants, and animation tools.

What works
- Extensive brush and drawing tools
- Free and open source
- Layer, mask, and animation systems
Keep in mind

What works
- Creative Cloud integration
- PSD collaboration
- Advanced retouching and generative tools
Keep in mind
- Subscription only
- Desktop version requires at least 8 GB RAM and 10 GB installation storage
macOS, Windows, web, and mobile
Fast social graphics and templates
Canva
Canva focuses on template-based graphics, collaboration, background tools, and direct publishing rather than pixel-level raster editing.
It can produce posts, flyers, thumbnails, and branded graphics through a browser or desktop app. Its editing model and selection tools differ from Paint.NET’s canvas-focused raster workflow.
What works
- Template and asset library
- Collaboration tools
- Browser and desktop access
Keep in mind
- Many advanced tools require Pro
- Limited precision compared with desktop raster editors
Browser and desktop app

- Filters and color adjustments
- Works across devices
Keep in mind
- Fewer compositing and drawing tools than Paint.NET
- Some features require Pro
Mac, web, and mobile
Cropping, resizing, and annotating right now
Apple Preview
Preview covers cropping, resizing, rotation, annotation, and format conversion but does not provide a layer-based composition workflow.
It is included with macOS and supports batch resizing and format conversion. It does not replace Paint.NET’s painting, layer, selection, or retouching toolsets.
What works
- Included with macOS
- macOS integration
- Batch resize and conversion tools
Keep in mind
- No proper layer workflow
- Limited painting, selection, and retouching tools
Built into macOS
