App icon problems are some of the most common reasons for App Store rejections, blurry home-screen icons, and unprofessional-looking PWAs. Here are the seven mistakes developers make most often — and how to fix each one with the free App Icon Generator.
---
1. Submitting a Transparent App Store Icon
The problem: Apple rejects 1024×1024 App Store icons that contain an alpha channel (transparency) — even if the transparent areas aren't visible.
The fix: When generating your iOS set, uncheck Transparent and choose a solid background color. The generator outputs a fully opaque 1024px PNG.
---
2. Pre-Rounding Your Icon's Corners
The problem: Both iOS and Android apply corner rounding/masking automatically. If you submit an icon that's already rounded, the OS rounds it again, creating an odd double-border or unintended white corners.
The fix: Always design and export a plain square icon (no pre-applied rounding). Use the generator's shape preview only to check how your design will look once masked — not to bake the shape into the file itself. (The square export option produces the unmasked square file that platforms expect.)

3. Important Content Touching the Edges
The problem: Logos, text, or symbols placed right at the edge of the canvas get clipped when Android applies a circular or rounded adaptive icon mask.
The fix: Add 15-20% padding using the generator's padding slider, then check the circle shape preview — if nothing important is cut off there, you're safe across all launcher shapes.

4. Missing Sizes Causing Build Warnings
The problem: Manually creating icon files one at a time is error-prone — it's easy to miss a size (like the 167px iPad Pro icon) or mislabel a file, causing Xcode warnings or blurry icons on specific devices.
The fix: Generate the complete set (13 iOS sizes, 6 Android sizes, 5 PWA sizes) in one pass — every file is named and sized correctly, eliminating manual errors.
---
5. Using a Low-Resolution Source Image
The problem: Starting from a small image (e.g., a 256×256px logo) and scaling it up to 1024px produces a soft, blurry App Store icon — the largest and most visible size.
The fix: Always start with the highest-resolution source you have (1024×1024px or larger). If your only source is small, consider redesigning from your original vector/design file rather than upscaling a raster export.

6. Forgetting the PWA / Favicon Set Entirely
The problem: Teams focused on native app stores often ship a website or PWA with no proper favicon — resulting in a generic browser icon or, worse, a broken image on "Add to Home Screen."
The fix: Generate the PWA set (favicons + Apple touch icon + manifest icons) in the same pass as your native icons — it's one extra checkbox.
---
7. Inconsistent Branding Across Platforms
The problem: When icons are designed separately for Android, iOS, and web (often by different people, at different times), subtle inconsistencies creep in — slightly different colors, padding, or cropping.
The fix: Generate all platforms from the same source image, in the same pass, with the same background and padding settings — guaranteeing visual consistency across every touchpoint.

Frequently Asked Questions
Will fixing these guarantee App Store approval?
These are the most common icon-related rejection causes — but Apple's review also covers app functionality, metadata, and content. Fixing icon issues removes one common rejection reason.
Can I re-generate icons if I change my logo later?
Yes — there's no limit. Re-upload your updated logo and regenerate the full set in seconds.
Is there a cost difference between generating a few icons vs the full set?
No — generating the full 24-icon set costs the same (free) as generating a single size.
Does this tool work on mobile browsers too?
Yes — the generator runs entirely in-browser via the Canvas API, which works on modern desktop and mobile browsers alike.
