Use this tool to convert your PNG images into ICO (Windows) or ICNS (macOS) icon formats.
1. Upload your PNG files (square, max 1024×1024 size) for best results.
2. Select the output format: ICO for Windows or ICNS for macOS.
3. Click Create and download your icon file.
PNG (Portable Network Graphics): PNG is ideal for creating icons because it is a lossless image format that supports transparency, high-quality colors, and preserves details.
ICO (Windows): Supports multiple sizes in one file, required for Windows shortcuts and applications. Using ICO ensures your icon looks sharp at any resolution.
ICNS (macOS): Used for macOS app icons, preserves quality at different resolutions and ensures your app icon displays correctly on all macOS devices.
Why I created this tool: Most icon converters I found simply rescale a single image, which can reduce quality. This website allows you to upload multiple PNG files of different sizes to generate a complete icon set, ensuring each size looks sharp and professional.
