Paint app gets its own .paint format to store layers and edits

When you hear “Microsoft Paint,” memories probably rush in: crude fill buckets, wonky freehand lines, and the surreal joy of making a pixel-perfect MS Paint birthday card. But Paint today is not the Paint of 1995. Over the last couple of years, Microsoft quietly rebuilt it into a surprisingly capable image app for Windows 11 — and this week the company added two deceptively simple features that change the way people will use it: a native project file format (.paint) that saves layers and edits, and an opacity slider for pencil and brush tools. Both are currently being tested with Windows Insiders in the Dev and Canary channels.

This isn’t just another minor UI polish. Saving as a project file turns Paint into a proper “work-in-progress” editor: instead of exporting a flattened PNG or losing your layers when you close the app, you can save everything — layers, edits, and settings — into a single .paint file and pick up exactly where you left off. Microsoft’s Dave Grochocki, principal product manager lead for Windows inbox apps, put it bluntly: “You can now save your creation as an editable Paint project file and seamlessly pick up where you left off.” The company documents the new flow: File → Save as project → choose location → .paint.

Why a `.paint` file matters

At a technical level, this is the sort of capability designers and power users take for granted in tools like Photoshop (.psd) or Affinity Photo — it’s how you keep edits non-destructive, move layers around, and return to ongoing work without starting over. For Paint, adding a project format does three practical things:

Transforms workflow. Paint becomes a place you can iterate in, not just doodle and export. That matters for casual creators, educators, meme makers, and anyone doing quick UI mockups.
Lowers the friction for beginners. People who wouldn’t buy a subscription to a pro app can still work in layers and save progress. That democratizes basic digital art and rapid prototyping.
Raises questions about interoperability. Microsoft hasn’t said the .paint format will be compatible with Photoshop or other editors, and there’s no evidence of PSD import/export yet — so expect .paint to be primarily a Paint-native format for now. That’s fine for many users, but pros will still need export options to move assets between tools. (Microsoft’s post doesn’t promise cross-app compatibility.)

Put another way: Paint is being shepherded from “simple tray of tools” toward “free lightweight editor” — not a Photoshop replacement, but a far more capable first stop for a lot of everyday tasks.

The small feature that feels huge: opacity sliders

Alongside project files, Paint is getting an opacity slider for the Pencil and Brush tools. It’s the little thing that makes layering actually useful: softening strokes, building up shading, or blending textures without resorting to multiple layers or manual opacity hacks. You’ll find the slider on the left side of the canvas when using these tools, Microsoft explains — a tiny UI change that expands Paint’s usefulness for sketching and digital painting.

This is emblematic of Microsoft’s approach: incremental, additive features that don’t rewrite the app overnight but make it progressively more useful. Over the last year, Paint has been getting features people asked for: layer support, transparency, background removal, and AI extras like sticker generation and generative fill — all gradual upgrades that cumulatively shift perceptions.

Snipping Tool and Notepad: the bundle that ships with Paint

Microsoft didn’t stop at Paint. The same Insider update adds a Quick markup mode to the Snipping Tool — pen, highlighter, eraser, shapes and recrop controls inside the capture process — aimed at streamlining quick annotations. That’s handy for screenshots that need on-the-fly edits before sharing.

And yes, there’s an AI tie-in: Notepad is gaining Summarize, Write, and Rewrite features on Copilot+ PCs, and—critically—these are available without a Microsoft 365 subscription because they can run on local models on capable Copilot+ machines. If you do have a cloud subscription, you can switch between local and cloud models “seamlessly.” Microsoft frames it as making premium AI more accessible while still offering cloud power for heavier tasks.

What this means for users (and Microsoft)

For everyday Windows users: Paint’s evolution reduces the number of times you need to install third-party software for simple editing. If your needs are cropping, layering, light shading, or quick collages, Paint will soon be able to handle them without exporting and stitching things together elsewhere.

For creators: .paint is a convenience, not a replacement. Pros will still rely on PSD workflows, HDR color management, and advanced plugins in pro apps. But for drafts, storyboarding, quick comps, and social graphics, Paint is now a legitimate, zero-cost option.

For Microsoft: this is a low-risk, high-visibility play. The company gets to show that Windows’ stock apps are being maintained and modernized — part of a broader narrative around “AI + Windows” and more useful inbox apps. Rolling features to Insiders first keeps development iterative and feedback-driven.

Bottom line

Microsoft has quietly been turning Paint into something worth revisiting. The .paint project files and opacity sliders are small features in isolation, but together they change how the app fits into real creative workflows: less an emergency doodle tool, more a fast, forgiving canvas for iteration. For millions of Windows users who never installed an alternative, Paint is becoming the first place to start a creative idea — and that matters.
