PNG

PNG Portable Network Graphics

PNG stores pixels with lossless DEFLATE compression and a full 8-bit alpha channel. It is the safe default for screenshots, logos, UI assets and anything with sharp edges or text, because every pixel survives exactly as drawn.

ICO

ICO is a container that holds one or more square icon images at different sizes. Browsers use it for favicon.ico and Windows uses it for application and shortcut icons.

Making a favicon from a PNG

For a favicon, start with a square PNG of at least 256×256 pixels. Choose the 16, 32 and 48 pixel sizes to build a single favicon.ico that browsers pick the right size from. For a complete set including Apple touch icons and a web manifest, use the Favicon Generator.

Why convert PNG to ICO?

PNG files usually come from screenshots, design tools and image downloads, where lossless storage keeps edges crisp. Photographs saved as PNG are often 3 to 10 times larger than the same photo as JPG or WebP. Choose ICO for a website favicon or a Windows shortcut icon.

PNG to ICO settings

Choose which icon sizes to embed. Non-square images are centred on a transparent square canvas. You can also cap the width and height, which resizes large photos in the same step.

Frequently asked questions

Will the ICO lose quality?

No. Both formats are lossless, so every pixel or sample in your PNG is kept exactly.

Is transparency kept when converting PNG to ICO?

Yes. ICO supports transparency, so transparent areas in your PNG stay transparent.
