The best App Store screenshot generator is the one that removes your biggest bottleneck. Template-and-localization platforms like AppScreens and AppLaunchpad suit teams shipping to many markets. 3D mockup tools like mockiso, Rotato and Previewed suit eye-catching hero images. fastlane frameit suits fully automated pipelines. Below, we compare seven tools honestly, including where our own product falls short.

What is an App Store screenshot generator?

An App Store screenshot generator is a tool that turns raw app screenshots into finished store images by adding device frames, backgrounds and captions, then exporting them at the sizes Apple and Google require. Some tools focus on templates and batch resizing. Others focus on rendering a realistic 3D device mockup.

Whichever tool you choose, the store rules stay the same. According to Apple's App Store Connect screenshot specifications, you can upload up to 10 screenshots per device size, in JPEG or PNG, with no alpha channels or transparency. For large iPhone displays, the accepted portrait sizes include 1320 × 2868 px, 1290 × 2796 px and 1260 × 2736 px. For pixel-level detail by device, see our App Store screenshot sizes guide.

Google Play's preview asset requirements allow up to 8 screenshots per device type, in JPEG or 24-bit PNG without alpha. Each side must be between 320 px and 3840 px, and the longer side can't be more than twice the shorter side. Google recommends at least four app screenshots at a minimum resolution of 1080 px.

How we compared these app store screenshot tools

We checked each tool's own website and documentation in November 2026 and looked at five criteria:

  • Visual style: flat frames, template layouts or true 3D renders.
  • Store workflow: size presets, localization and direct upload.
  • Platform: browser, desktop app or command line.
  • Free option: what you can do before paying.
  • Best fit: the team and task where the tool clearly wins.

Prices and limits change often, so treat every number below as a snapshot and check the vendor's pricing page before buying.

The 7 tools, one by one

1. mockiso: best for fast 3D device mockups in the browser

mockiso (our product) turns a screenshot into a realistic 3D device mockup rendered in the browser with WebGL, with nothing to install. It covers more than 40 logo-free devices, from the iPhone 18 Pro and Galaxy S24 Ultra to foldables like the Galaxy Z Fold7, plus iPads, laptops, watches and TVs. You can pick an angle preset or rotate freely, set the lens (24–135 mm), tune lighting and shadows, and add an App Store style headline and subline.

The duo and trio layouts place several devices with consecutive screenshots, which helps with panoramic store sets. Exports come out as PNG, JPEG or WebP, with canvas presets for stores and social media and up to 8192 px with 2× tiled rendering on paid plans.

Honest limits: mockiso doesn't localize captions into dozens of languages or upload directly to App Store Connect. If you need 30 locales, pair it with a localization tool or build captions in Figma. Plans start free, and Pro costs $9/month. See pricing for current limits.

2. AppScreens: best for multi-store, multi-language releases

AppScreens advertises 150+ template sets with 500+ editable layouts. It offers real, clay, 3D, outline or frameless device frames, translation into 80+ languages including right-to-left scripts, and direct upload to App Store Connect and Google Play Console, including custom product page and product page optimization variants. It also has presets for the Microsoft Store, Chrome Web Store, Amazon Appstore and Huawei AppGallery. The free plan covers up to 5 screenshots.

3. AppLaunchpad: best for template variety

AppLaunchpad describes itself as a browser-based app screenshot generator with 1000+ pre-built templates. It covers recent iPhones, Android phones, iPads and tablets, and it supports screenshots in multiple languages. If you want to start from a finished layout and swap in your screens, this tool fits well.

4. Previewed: best low-cost option for 3D video

Previewed offers 2D mockups, 3D snapshots and animations, panoramic App Store screenshots and app promo videos. The free Lite tier gives unlimited 2D exports at 720p under a CC Attribution license. Plus costs a one-time $9.99 for 10 high-resolution exports, 3D and video, and a commercial license. Pro costs $19/month for unlimited exports.

5. Rotato: best for animated 3D on a Mac

Rotato is a 3D device mockup generator and animator. It has 30+ built-in devices, custom 3D model import, an animation timeline, a Figma plugin, and image or video export up to 8K. The main app requires macOS 11 or newer, and a web version is in public beta. If you need an App Store preview video with camera moves, Rotato is the strongest choice here.

6. fastlane frameit: best for automated pipelines

frameit is an open-source fastlane action that adds device frames to iOS, Android and Mac screenshots with one command. It supports backgrounds, titles and keywords, and localized text through .strings files. The look is flat rather than 3D, but if you already capture screenshots automatically in CI, frameit keeps every release consistent with no manual work.

7. Figma community templates: best for full custom design

Figma Community hosts many free App Store screenshot template files. You get full control over type, layout and brand, but resizing for every device and locale is manual. Many teams combine approaches: render the device in a mockup tool, then compose the final set in Figma.

Which App Store screenshot generator should you choose?

Choose based on the job that takes you longest, not on the template gallery. Here is a quick decision guide:

  • Indie developer, one language, wants a premium look fast: mockiso or Previewed.
  • Team shipping in 10+ locales: AppScreens or AppLaunchpad.
  • Need animated 3D video: Rotato, or Previewed on a budget.
  • Screenshots already automated in CI: fastlane frameit.
  • Brand-heavy design team: Figma, optionally with 3D renders imported from a mockup tool.

Whatever you pick, the image still needs to say something. Our guides to screenshot captions and 2026 screenshot trends cover the content side.

How do you make App Store screenshots with mockiso?

You can produce a store-ready 3D screenshot in mockiso in a few minutes:

  1. Sign up (every new account gets a 24-hour Pro trial, no card required) and create a new project.
  2. Pick a device, such as iPhone 17 Pro Max for iOS or Pixel 9 Pro for Google Play screenshots.
  3. Upload a screenshot by clicking, dragging and dropping, or pasting with Ctrl/Cmd+V.
  4. Choose an angle preset (front, hero left/right, float) or drag to rotate, then fine-tune the lens and lighting.
  5. Set a solid or gradient backdrop, or pick one of 70 backdrop templates. Then add a headline and subline.
  6. Switch to a duo or trio layout if you want consecutive screens to flow across images.
  7. Pick a store canvas preset and export as PNG or JPEG.

Tip: mockiso can export transparent backgrounds, but Apple and Google both reject images with alpha channels. Use a solid, gradient or image backdrop for store uploads, and keep transparency for websites and decks.

Key takeaways

  • App Store Connect accepts up to 10 JPEG or PNG screenshots per device size, with no transparency. Google Play accepts up to 8 per device type.
  • For localization and direct upload at scale, AppScreens has the deepest feature set of the tools compared here.
  • For 3D device mockups, mockiso (browser, stills), Rotato (Mac, animation) and Previewed (browser, budget video) are the main options.
  • fastlane frameit is free, open source and best when screenshots are already generated in CI.
  • Always confirm current pricing on each vendor's site, because limits change often.

Conclusion

No single App Store screenshot generator wins every job. Match the tool to your bottleneck: localization, automation, animation or visual polish. If you want realistic 3D device mockups without installing anything, start a free mockiso trial and render your first store image in minutes, or browse the full device list first.
