Mac App Store Screenshot Sizes: Complete Guide (2026)

Every accepted Mac screenshot size

Unlike iPhone screenshots (which require specific device dimensions), Mac screenshots are simpler. Apple accepts exactly four resolutions, all at the same 16:10 aspect ratio. You only need to provide one size, and Apple will display it across all Mac product pages.

Which size should you pick? Go with 2880×1800. It is the native resolution for the 15-inch and 16-inch MacBook Pro displays, and Apple will downscale it gracefully for smaller screens. Starting at the highest resolution means your text, icons, and UI details will look crisp everywhere. If your design workflow makes 2880 pixels wide unwieldy, 2560×1600 is a solid second choice.

File format and upload rules

Apple enforces the same file format rules for Mac screenshots as it does for iOS, but developers who are new to Mac listings sometimes trip on the details. Here is exactly what App Store Connect expects.

Format: PNG or JPEG. Apple accepts .png, .jpg, and .jpeg extensions. PNG is almost always the better choice because it preserves lossless detail in text and UI elements. JPEG compression can blur fine text at smaller sizes, especially on non-Retina displays.

Color space: RGB only. Apple will reject images in CMYK or grayscale color spaces. If you export from Figma, Sketch, or any standard screen design tool, RGB is the default. Watch out if you receive assets from a print designer.

Transparency: Not allowed. Your screenshots must have a solid background with no alpha channel. PNG files with transparency will be rejected during upload. If your screenshot has a transparent background, flatten it onto a solid color before exporting.

File size limit: Each screenshot must be under 10 MB. At 2880×1800, a typical PNG with a full-color UI screenshot comes in between 2 and 6 MB, so this limit is rarely an issue. If you are hitting it, check whether your export includes unnecessary metadata or an embedded color profile.

Number of screenshots: Minimum 1, maximum 10. Apple does not specify a minimum word count or content requirement for what the screenshots show, but they must be representative of your app’s actual functionality. Apple reviewers will flag screenshots that show misleading or unrelated content.

How Mac screenshots differ from iOS and iPad

If you already have iPhone or iPad screenshots, you might wonder whether you can reuse them for your Mac listing. The short answer is no. Here is why.

Orientation: Mac screenshots are always landscape. iPhone screenshots are nearly always portrait. The aspect ratios are incompatible, so you cannot simply rotate or crop one format into the other.

Aspect ratio: Mac uses 16:10 exclusively. iPhone uses ratios that vary by device (roughly 19.5:9 for modern iPhones). iPad Pro uses 4:3 in portrait. None of these map to 16:10 without significant cropping or letterboxing.

UI expectations: Users browsing the Mac App Store expect to see a desktop interface. That means a macOS menu bar, window title bars, sidebars, and toolbars. Showing a mobile-style UI inside a Mac listing signals that the app was not properly adapted for the desktop, which hurts conversion.

Mac Catalyst and universal apps: Even if your app started as an iPad app and you brought it to Mac using Catalyst, your Mac listing screenshots must show the macOS version of the UI. Apple enforces this. The good news is that Catalyst apps automatically gain native macOS chrome (title bar, menu bar, resize handles), so capturing the desktop version is straightforward.

How to capture Mac app screenshots

macOS has built-in screenshot tools that work well for App Store submissions. You do not need third-party capture software.

Window capture (Cmd + Shift + 4, then Space): This captures a single window with a transparent background and a drop shadow. It is the cleanest method for isolating your app window. After capturing, you will need to flatten the transparency onto a solid background before uploading to App Store Connect.

Full screen capture (Cmd + Shift + 3): This captures everything on your display, including the menu bar, dock, and desktop wallpaper. It works if you want to show your app in context, but you will need to crop or resize the result to match one of the accepted 16:10 dimensions.

Screenshot app (Cmd + Shift + 5): Opens a toolbar that lets you choose between full screen, window, or region capture. You can also set a timer, which is useful for capturing menus or popovers that dismiss on click.

Resolution matters: If you are capturing on a Retina MacBook Pro, the raw screenshot will already be at 2x resolution (for example, a 1440×900 logical display produces a 2880×1800 pixel screenshot). This is exactly what you want for the recommended 2880×1800 size. If you are on a non-Retina display, the captures will be at 1x, and you will need to work at one of the smaller accepted dimensions.

Design tips for Mac App Store screenshots

Mac screenshots have more canvas to work with than phone screenshots, but that extra space can work against you if you fill it poorly. Here are practical guidelines for making the most of the landscape format.

Show the full window, not a cropped fragment. Users want to understand what the app looks like in daily use. A complete window with sidebar, toolbar, and content area communicates far more than a zoomed-in crop of one feature.

Use a clean desktop background. If your screenshot includes any desktop area outside the app window, keep the wallpaper simple and neutral. A busy or dated desktop wallpaper distracts from the app itself. A solid color or subtle gradient works best.

Add a caption above or below the window. Just like phone screenshots, Mac screenshots benefit from a short headline that explains the value of what the user is seeing. Place the caption on a colored or gradient background behind the app window, similar to what you would do for an iPhone screenshot layout, but in landscape orientation.

Lead with your strongest screen. The first screenshot is the one most people see. Pick the screen that best communicates your app’s core value. For a productivity app, that might be the main workspace. For a creative tool, it might be the canvas with a finished project visible.

Keep text large enough to read at small sizes. Mac screenshots are often displayed at a much smaller size than their actual pixel dimensions. If you add captions, headlines, or callouts, make sure they remain legible when the image is scaled down to around 400 pixels wide in the store listing.

Show dark mode and light mode. macOS users are split between appearance preferences. If your app supports both, include at least one screenshot in each mode. This signals polish and earns trust.

Common mistakes that cause rejections

Apple’s review team checks Mac screenshots during the app review process. Here are the most common reasons Mac screenshots get flagged.

Wrong aspect ratio. This is the number one rejection reason. If your image is not exactly 16:10 (or one of the four accepted pixel dimensions), App Store Connect will reject it during upload. Double-check your export settings before uploading.

Transparency in the image. Window captures on macOS include a transparent background by default. If you upload the raw capture without flattening it, Apple will reject it. Open the screenshot in Preview, export as PNG with no alpha channel, or place the window on a solid background first.

Using iOS screenshots for the Mac listing. This happens more often than you might expect with universal apps. Even if the interface looks similar, App Store Connect validates that Mac screenshots match the macOS size requirements. The upload will fail if the dimensions are wrong.

Misleading content. Apple requires screenshots to show actual app functionality. If your screenshots show features that are not yet implemented, or display stock photos that do not represent the app, your submission may be rejected during review.

Visible personal or sensitive data. This is easy to overlook. If your app displays user data (email addresses, calendar events, file names), make sure your screenshots use sample data or test accounts. Apple has flagged submissions for showing real personal information.

Screenshots for Mac Catalyst and SwiftUI apps

The rise of Mac Catalyst and SwiftUI has made it much easier to bring iOS apps to macOS. But the screenshot requirements remain separate. Here is what to keep in mind.

Mac Catalyst apps run in a macOS window with a native title bar, menu bar support, and standard Mac keyboard shortcuts. When you capture a Catalyst app for screenshots, the result already looks like a native Mac app, which is exactly what you want.

SwiftUI apps that target both iOS and macOS can look quite different on each platform. The Mac version typically has a wider layout, a sidebar navigation pattern, and macOS-style controls. Always capture the Mac target specifically rather than resizing an iPad screenshot.

For both Catalyst and SwiftUI apps, run the app on an actual Mac (or in the macOS Simulator in Xcode) to capture screenshots. Do not use the iPad Simulator and attempt to resize the output. The UI scaling and window chrome will be wrong.

A practical workflow for Mac screenshots

Here is a step-by-step process that works well for indie developers shipping Mac apps.

1. Prepare your app state. Open the app and navigate to the screen you want to capture. Load it with realistic sample data. If possible, set the window size to fill most of the screen so the UI feels spacious rather than cramped.

2. Capture on a Retina Mac. Use Cmd+Shift+4 then Space to capture just the app window. On a Retina display, this gives you a 2x resolution image automatically. Save the capture.

3. Place the window on a background. Open the capture in your design tool (Figma, Sketch, Photoshop, or even Keynote). Create a 2880×1800 canvas with a solid or gradient background. Place your app window screenshot on the canvas, centered or slightly offset to leave room for a caption.

4. Add a caption. Write a short, benefit-focused headline above or below the window. Keep it under 8 words. Use a large, bold font that remains legible at small display sizes. A tool like Screenshot Otter can automate this for you with pre-built templates, though the manual approach works fine for a small number of screenshots.

5. Export as PNG. Make sure the export is RGB with no alpha channel. Verify the dimensions are exactly 2880×1800 (or whichever size you chose).

6. Upload to App Store Connect. In the App Store Connect dashboard, navigate to your app’s version, scroll to the Mac screenshots section, and upload your images. You can drag and drop to reorder them. Apple displays them in the order you set.

App previews (video) for Mac

In addition to static screenshots, Apple allows you to upload app preview videos for your Mac listing. These are short videos (15 to 30 seconds) that auto-play on the product page.

Mac app previews must be landscape at a 16:9 aspect ratio, with a resolution of 1920×1080 pixels. Note that this is a different aspect ratio from the static screenshots (16:9 vs 16:10), so you cannot simply export a video at your screenshot dimensions.

App previews are optional but effective. They give potential users a real sense of how your app works in motion. For productivity apps, showing a quick workflow from start to finish is especially compelling.

Do I need screenshots for different Mac display sizes?

No. Unlike iPhone listings (which require screenshots for multiple display sizes), Mac listings accept one set of screenshots that Apple uses across all Mac product pages. You pick one of the four accepted sizes, upload your screenshots, and Apple handles the rest.

That said, if you provide screenshots at the largest size (2880×1800), Apple can downscale them cleanly. If you provide screenshots at the smallest size (1280×800), they may look fuzzy when displayed on Retina Macs. This is another reason to start at 2880×1800.
