Frequently Asked Questions
What is an ICO file and why would I need one?
ICO files are Windows icon format files that can contain multiple image sizes in a single file. They're commonly used for website favicons, desktop application icons, and folder icons. ICO files are essential for displaying crisp icons at different resolutions across various contexts.
What PNG image size works best for ICO conversion?
Square PNG images work best, ideally 256x256 pixels or larger for high-quality results. The converter will resize your image to the selected ICO size while maintaining aspect ratio. Starting with a larger, high-resolution PNG ensures better quality when scaled down to smaller icon sizes.
Which icon sizes should I choose for different purposes?
Use 16x16 or 32x32 for website favicons, 48x48 for desktop shortcuts, 64x64 for file type icons, and 128x128 or 256x256 for application icons. Many websites use multiple sizes (16x16, 32x32, 48x48) to ensure crisp display across different devices and contexts.
Does the converter preserve transparency from PNG files?
Yes, our converter preserves transparency from PNG files when creating ICO files. This is particularly important for icons that need to blend seamlessly with different background colors. Transparent backgrounds ensure your icons look professional across various applications and themes.
Can I convert multiple PNG files to ICO at once?
Yes, our converter supports batch processing. You can select multiple PNG files and convert them all to ICO format simultaneously. Each PNG file will be converted to a separate ICO file, making it efficient for creating multiple icons for different purposes.
Will my converted ICO files work on Mac and other platforms?
While ICO is primarily a Windows format, our generated ICO files follow standard specifications and work across platforms. Modern browsers and many applications on Mac and Linux can display ICO files, especially for favicons. For maximum compatibility, consider also creating PNG icons for non-Windows platforms.
