PixResize Image to 1024x1024
1024x1024 pixels is the default output size for many AI image generators (DALL-E, Midjourney) and the maximum Apple App Store icon size. A versatile large square that scales down cleanly for any use.

When You Need 1024x1024 Pixel Images
The 1024x1024 pixel square serves two major roles: it is Apple's required app icon size for the iOS App Store, and it is a standard output resolution for AI image generation. If you are an iOS developer or working with AI-generated imagery, this dimension is part of your regular workflow.
Apple requires every iOS app to include a 1024x1024 PNG icon that Xcode and the App Store use as the master icon file. The system generates all smaller sizes (180x180 for iPhones, 167x167 for iPad Pro, 76x76 for iPad, and others) from this single source. The icon must be a PNG with no transparency, no rounded corners (iOS applies its own superellipse mask), and should use the full canvas without built-in padding. macOS also uses 1024x1024 as its maximum icon size, appearing in Finder's large icon view.
AI image generation has made 1024x1024 ubiquitous. DALL-E 3, Stable Diffusion XL, and Midjourney v5+ output at 1024x1024 by default. If you are post-processing AI-generated images — cropping, adjusting, compositing, or preparing for different use cases — you are working at 1024x1024 as your base resolution. Many AI art marketplaces and print-on-demand services accept 1024x1024 as a minimum submission size.
E-commerce platforms consider 1024x1024 a high-quality product image size. Amazon enables its zoom feature starting at 1000x1000 (1024x1024 exceeds this threshold). Shopify themes that support zoom-on-hover work well at this resolution. For product photography, 1024x1024 provides enough detail for customers to inspect textures, read small text, and evaluate quality — the image is genuinely useful for purchase decisions, not just identification.
Digital art, NFTs, and profile-picture collections (PFPs) commonly use 1024x1024 as their standard resolution. The dimension provides enough detail for display on high-DPI screens while keeping file sizes manageable for web delivery and blockchain storage.
At 1024x1024, a JPEG at quality 85 runs 100-180KB. PNG (required for app icons) runs 150-400KB depending on image complexity. WebP offers the best compression for web display at 75-130KB.
1024x1024 vs Similar Large Square Dimensions
| Dimension | Aspect Ratio | Common Use | File Size (JPEG q85) | Best For |
|---|---|---|---|---|
| 1024x1024 | 1:1 | iOS App Store icon, AI generation, high-quality products | 100-180KB | Apple ecosystem, AI art, Amazon zoom |
| 512x512 | 1:1 | Google Play icon, Telegram stickers, YOLO models | 50-85KB | Android apps, ML pipelines |
| 800x800 | 1:1 | E-commerce detail images | 80-130KB | Product detail pages, marketplace minimums |
| 1200x1200 | 1:1 | Large social squares, premium product images | 150-250KB | Marketing materials, premium e-commerce |
| 2048x2048 | 1:1 | Apple Music artwork, ultra-high-quality | 350-550KB | Maximum quality for digital distribution |
Notes: For iOS development, this is the single most important icon size — all other icon sizes derive from it. Design at 1024x1024 first, then verify the design reads well when scaled to 60x60 and 29x29 before submitting.
Frequently Asked Questions
Why does Apple require a 1024x1024 icon?
Apple uses the 1024x1024 PNG as the master icon for the App Store and marketing materials. All smaller icon sizes (home screen, Spotlight, Settings, notifications) are generated from this source. Xcode requires it in the asset catalog. The icon appears at full 1024x1024 on the App Store detail page on iPad and in iTunes. Without it, your app cannot be submitted for review.
How do I make a 1024x1024 app icon?
Design your icon at 1024x1024 in your preferred design tool. Export as PNG with no transparency and no rounded corners — Apple applies its own mask. If starting from a larger source, use Pixotter's resize tool to scale to exactly 1024x1024. Test readability at 60x60 and 29x29 before submitting. Bold shapes and high contrast are essential — fine detail disappears at small sizes.
Is 1024x1024 good for product images?
Yes — it exceeds Amazon's 1000x1000 zoom threshold and provides excellent detail for product inspection. At 1024x1024, customers can evaluate texture, read labels, and assess quality. For most e-commerce contexts, this is a high-quality product image size. Only consider 2048x2048 if you need maximum zoom depth or ultra-high-quality marketing materials.
How do I resize AI-generated images from 1024x1024?
AI outputs (DALL-E, Stable Diffusion) typically come at 1024x1024. To use them for different purposes, resize with Pixotter: 1080x1080 for Instagram posts, 1920x1080 for desktop wallpaper (with cropping), or 512x512 for app icons. Use "cover" or "contain" fit modes depending on whether you prefer cropping or padding.
What format should I use at 1024x1024?
PNG for app icons (Apple requirement) and images needing transparency. JPEG at quality 85 for photographs and product images (100-180KB). WebP for web delivery (75-130KB, about 30% smaller than JPEG). For AI art portfolios and digital art, PNG preserves the most detail. See the best image format guide.
Can I generate all app icon sizes from a 1024x1024 source?
Yes. Drop your 1024x1024 icon into Pixotter, then resize to each required size: 512x512 (macOS, Google Play), 192x192 (Android PWA), 180x180 (iPhone Retina), 167x167 (iPad Pro), 152x152 (iPad), 120x120 (iPhone), and smaller sizes as needed. Use batch mode to prepare all sizes efficiently. Also see our favicon size guide for web-specific icon sizes.
How It Works
Drag and drop any image — JPEG, PNG, WebP, AVIF, and more are all supported.
The tool pre-fills the target dimensions (1024×1024 pixels). Choose fit mode: contain (preserve ratio), cover (fill and crop), or stretch (exact dimensions).
Your resized image is ready. Optionally compress or convert the format before downloading.
