App Store screenshots are arguably more important than the app description in driving downloads — they are the visual proof of what your app does and how it looks. Apple requires screenshots at specific device dimensions, and high-quality screenshots directly impact conversion rates on your App Store listing page. At imgresizr.com, you can create and resize App Store screenshots at the correct dimensions, for free.

How to Create App Store Screenshots at imgresizr.com
Take screenshots on your device or create device mockup images that show your app UI. Upload to imgresizr.com. Use the Resize tool to set the exact required dimensions for each device type — Apple requires at least one 6.5-inch iPhone screenshot and one iPad Pro screenshot if your app supports iPad. Use the Enhance tool to ensure screenshots look vibrant and clear. Use the Caption tool to add descriptive text overlays that highlight key features — "Track your workouts in real time" or "Sync across all your devices." Most successful App Store screenshots use 5 images per device type. Compress to under 8MB per screenshot as required by Apple.
App Store Screenshot Best Practices
- The first screenshot is the most important — it appears in search results before users tap for more
- Include a feature headline on each screenshot — screenshots with text convert better than those without
- Show actual app UI, not abstract artwork — users want to see what they are downloading
- Use consistent visual style across all screenshots for a professional, cohesive presentation
- A/B test screenshots using Apple's Product Page Optimisation feature if available to your account
