Why Convert PNG to ICO?

ICO is the icon container Windows uses for favicons, desktop shortcuts and application icons. Our converter rescales your PNG into the standard 16, 32, 48 and 256 pixel sizes and packs them into a single ICO file, so browsers and Windows can pick the sharpest version for every context. PNG transparency is kept intact, which means your favicon or app icon keeps its clean edges on any background color.

Multi-Size Icons

Every ICO packs 16, 32, 48 and 256 pixel versions so your icon looks sharp at any scale.

Transparency Kept

Alpha transparency from your PNG carries into the icon for clean edges on any background.

No Uploads, No Cost

Icons are built right in your browser, free, with no watermark and no account required.
