#How to Use This Tool
#Mathematical Formula & Standards
#Edge Cases & Technical Considerations
iOS App Store Transparency Rejection
App Store Connect automatically rejects icon uploads containing alpha transparency channels or transparent layers. For iOS production submission, ensure your background is set to a solid color or gradient.
Android Adaptive Icon Safe Zones
Different Android device manufacturers (Samsung, Google, Xiaomi) apply distinct masks to app icons. Keep your core glyph within a 15%–20% inner padding margin to prevent OEM clipping.
Multi-Resolution Favicon ICO Compatibility
Legacy desktop browsers and Windows shortcuts expect a binary `.ico` container. Our engine packs 16×16, 32×32, and 48×48 frames into a single binary without third-party dependencies.
#Frequently Asked Questions
Q:Are my uploaded images stored on any server?
No. regula.tools processes all images 100% locally in your browser memory using the HTML5 Canvas API and Web Cryptography. Your files are never uploaded to any remote server or third-party service.
Q:Why does Apple require square icons without rounded corners?
Apple strictly requires developers to submit square icons (1024×1024) without pre-rounded corners or transparency. iOS, iPadOS, and macOS automatically apply the exact hardware-matched superellipse mask and system lighting effects at runtime.
Q:What sizes are required for Progressive Web Apps (PWAs)?
The W3C Web App Manifest specification recommends at least two icon sizes: 192×192 for home screen launchers and 512×512 for high-DPI splash screens. Google also recommends an icon with "purpose": "maskable" for Android home screens.
Q:Can I download individual icon resolutions instead of the full ZIP?
Yes. Every icon resolution card in the preview grid includes an instant single-click download button for that specific PNG file.
