How do I convert PNG to ICO?

Upload your PNG file above. It is converted to ICO automatically (change the output format or quality in the Settings tab if you need to), then click Download. There is nothing to install.

Does converting PNG to ICO lose quality?

Each icon size is scaled down from your image and stored without further compression, so small sizes stay crisp.

Will the ICO keep the transparent background?

Yes. ICO supports smooth, partial transparency, so transparent areas stay transparent.

PNG or ICO: which should I use?

Use PNG for screenshots, logos, text graphics and cut-outs. Use ICO for website favicons and Windows app or shortcut icons. Keep in mind the main drawback of ICO: icons are square and at most 256 × 256 pixels.

PNG stores every pixel exactly and supports smooth transparency, which makes it the go-to format for screenshots, logos and graphics, at the cost of large files for photos.

What sizes does the ICO file include?

The standard icon sizes of 16, 32, 48, 64, 128 and 256 pixels, skipping any larger than your image. Browsers and Windows pick the best size automatically.

Is the PNG to ICO converter free?

Yes. Convert, preview and download a single result without creating an account. Premium adds batch conversion (many files into one ZIP) and larger uploads.

Why convert PNG to ICO?

Transparent areas stay transparent: ICO supports smooth, partial transparency just like PNG.
One ICO bundles the standard 16 to 256 px icon sizes (up to the size of your image), ready for a favicon.ico or a Windows shortcut.

What to expect when converting PNG to ICO

Icons are square, so a non-square image is centred on a transparent square. Sizes larger than your image aren’t created, so start from at least 256 × 256 pixels.
Your original PNG file isn’t changed: you download a new ICO copy.
