Tips for Best Results

For optimal icon quality, use PNG images with transparent backgrounds. Square images work best as they will be cropped to the exact dimensions. For multi-size ICO files, start with a high-resolution PNG (256x256 or larger) to ensure all smaller sizes maintain sharpness. Our converter automatically handles aspect ratio preservation and centers the image for perfect cropping.
