App Store Screenshot Generator — frame + headline at exact store sizes
The App Store screenshot generator builds store-ready app shots: tuck your app screenshot into a device frame, add a marketing headline and a spotlit background, then export at the exact 2026 store sizes — iPhone 6.9" (1320×2868), iPad 13" (2064×2752) and Google Play presets are all built in. Exports are forced to no-alpha RGB PNG (Apple rejects screenshots that are even 1px off, so pixel-precision matters). It all renders locally in your browser; your screenshot isn't uploaded.

Why App Store screenshots need a "frame + headline," not a bare screenshot
Open any top-ranking app's store page and you'll notice the screenshots are almost never bare — they're "an interface inside a device frame + a big headline + a branded background." The reason is simple: store screenshots are a conversion tool, not a manual. A user swipes past your screenshot in half a second, and that headline ("Remove watermarks in one tap," "Generate mockups in 3 seconds") is what's actually selling. The frame lends "this is a real app" credibility, and a consistent background color makes 3–10 screenshots look like a designed storyboard rather than random captures. MockCat turns this "frame + headline + background" recipe into a fill-in tool — you just swap the screenshot and edit the copy, and the layout aligns itself.
Sizing is where App Store screenshots trip up most, and it has to be exact. The 2026 mainstays are iPhone 6.9" (17 Pro Max, 1320×2868) and iPad 13" (M4, 2064×2752), with 6.7" and 6.5" compatibility tiers; Google Play follows its own Android spec. Apple's review is strict about dimensions — being 1px off, or shipping a PNG with an alpha channel, can get you rejected outright. MockCat exports at the exact pixels for the device class you pick and forces no-alpha RGB, precisely so your export passes the first time without you re-measuring in Photoshop.
A few field-tested tips for a high-converting set: the first screenshot matters most (many users only see one), so put the strongest hook and prettiest UI first; lead headlines with a verb and describe "what the user gets," not the feature's name; keep one background and font across 3–10 shots for visual continuity; and write each market's headlines natively rather than translating (search terms and phrasing differ). MockCat supports applying one template across a batch — pair it with our screenshot mockup tool to frame each UI first, then add headlines and backgrounds — and you'll produce a full store set in minutes, all local, no upload, free and watermark-free.
App Store Screenshot Generator

App Store Screenshot Generator
- Pixel-exact sizes: every 2026 store size is built in, exported as no-alpha RGB — dodging Apple's "1px off, rejected" trap.
- Headline + frame in one step: a store shot's value is the screenshot plus a one-line hook — this composites both at once.
- Local rendering: your app screenshot isn't uploaded — unreleased UI shouldn't go to a server first.
- Bilingual: works for the App Store abroad and Chinese app markets with the same tool.
Frequently asked questions
What are the main 2026 App Store screenshot sizes?
iPhone's mainstay is 6.9" (17 Pro Max, 1320×2868 px); iPad is 13" (M4, 2064×2752). There are 6.7" and 6.5" compatibility tiers. Google Play uses its own Android sizes. This tool turns them into one-click presets and exports at exact pixels.
Why strip the alpha channel on export?
App Store Connect expects RGB images without transparency; PNGs with alpha can be rejected. This tool flattens the background and removes alpha on export, outputting standard RGB so it passes the first time.
Can I make a full set (3-10) of screenshots?
Yes. Stores usually want 3–10 consistent screenshots. The tool lets you reuse one device frame, background and text style; pair it with "batch" to produce a set fast — and put your strongest hook first.
Is my app screenshot uploaded?
No. All rendering happens locally with canvas; unreleased UI never leaves your device.
How is it different from Previewed / AppMockup?
Previewed shines at 3D/animated screenshots (a heavy feature we skip); MockCat does the affordable static slice — frame + headline + exact store sizes — free, local, bilingual, watermark-free. Use Previewed for 3D motion; use MockCat to quickly ship free static store art.
