PNG to ICO Converter - Frequently Asked Questions
What sizes are included in the ICO file?
The ICO contains multiple sizes: 16x16 (browser tab), 32x32 (desktop shortcut), 48x48 (Windows Explorer), and 256x256 (high-res displays). Windows automatically picks the best size for each use.
Can I use this for Windows application icons?
Yes! The generated ICO files work for Windows apps, desktop shortcuts, folders, and files. Simply set the ICO as your application's icon resource in your development environment.
What's the ideal source image size?
Use a square PNG at least 256x256 pixels (512x512 recommended). The converter scales down to create all needed sizes. Higher resolution sources create sharper icons, especially for 256x256 displays.
Will transparent backgrounds work?
Yes! PNG transparency is preserved in the ICO file. Perfect for logos and icons that need to blend with different backgrounds. The 256x256 size supports full alpha channel transparency.
