ICO Converter transforms your images into Windows ICO icon format instantly. Convert PNG, JPG, or WebP files to ICO for use as favicons, desktop icons, or application icons. The tool creates multi-resolution ICO files containing multiple sizes in a single file for optimal display across different contexts.
Upload your image file to start the ICO conversion. Select which icon sizes you need - from 16x16 for small favicons up to 256x256 for high-DPI Windows displays. The converter automatically resizes your image with high-quality scaling and packages all selected sizes into a single ICO file. Download your multi-resolution icon ready for websites or Windows applications.
Different icon sizes serve different purposes: 16x16 appears in browser tabs and taskbars, 32x32 is the standard favicon size, 48x48 displays on Windows desktop, and 256x256 provides crisp icons on high-resolution displays. Including multiple sizes in one ICO file ensures your icon looks sharp everywhere - Windows automatically selects the best size for each context.
Use ICO format for Windows application icons, desktop shortcuts, and traditional favicons. While modern browsers support PNG favicons, ICO provides the best compatibility for older browsers and Windows applications. For website favicons, include 16x16, 32x32, and 48x48 sizes. For Windows desktop applications, add 64x64, 128x128, and 256x256 for high-DPI support.
A multi-size ICO file contains several resolutions in one file, allowing Windows and browsers to choose the optimal size automatically. This eliminates pixelation from upscaling small icons and prevents wasted bandwidth from downloading oversized icons. One ICO file replaces multiple separate image files while ensuring perfect display quality at any size.
