Need a clean, professional icon for a Windows app, folder, shortcut, or desktop tool? Our Image to ICO converter helps you turn PNG, JPG, WebP, and BMP into a high-quality ICO file—the standard icon format used by Windows. Upload your image, convert instantly, and download a ready-to-use icon that looks sharp in every size.

What is an ICO file?

An ICO (Icon) file is a special image container designed for Windows icons. Unlike a normal image format that stores one fixed size, an ICO file can include multiple icon sizes in one file (for example 16×16, 32×32, 48×48, 64×64, 128×128, and 256×256). This is why a good icon stays crisp whether it’s displayed in the taskbar, Start menu, desktop, or File Explorer.

Why convert an image to ICO?

If you’ve ever used a PNG or JPG as an icon and noticed it looks blurry or poorly cropped, that’s because standard images aren’t optimized for Windows icon scaling. Converting to ICO gives you:

• Perfect sizing across Windows views (small, medium, large icons)

• Cleaner edges for logos, symbols, and app icons

• Support for transparency (best when converting from PNG)

• A single file that works for shortcuts, folders, and software builds

Whether you’re building an app, customizing your desktop, or preparing a brand asset, converting your image to ICO is the fastest way to get a Windows-ready icon.

Best ICO sizes (recommended)

For maximum compatibility, the best ICO files include multiple sizes—especially:
16×16, 32×32, 48×48, 64×64, 128×128, 256×256

This ensures your icon looks sharp everywhere, from tiny toolbar views to high-resolution displays.

Tips for a sharper icon

Want the best results from your PNG to ICO or JPG to ICO conversion?

• Start with a square image (or let the tool auto-crop to a square)

• Use a high-resolution source (512×512 or 1024×1024 is ideal)

• Prefer PNG if you need a transparent background

• Keep the design simple—fine details can disappear at 16×16

• Add padding around logos so they don’t look “cut off” in small sizes

FAQ: Image to ICO

Can I convert PNG to ICO with transparency?

Can I convert JPG to ICO?
Yes. JPG icons will have a solid background (since JPG doesn’t support transparency).

Does ICO work for website favicons?
Yes—ICO is commonly used for favicons too, but a full favicon set may also include PNG sizes for modern browsers.
