• A high-detail iconInclude 256px in the ICO for high-DPI displays alongside the smaller sizes.
• A quick shortcut iconConvert a square PNG to a 48px ICO for a desktop shortcut.

• Start squareA square source keeps the icon from stretching. Non-square images are centered and scaled to fit.
• Keep transparencyA transparent PNG gives an icon that blends into any background.
• Include small sizes16 and 32 px matter most for browser tabs; add 48 and larger for other uses.

For each size you select, the tool scales your PNG onto a square canvas and encodes it as PNG data, then packs all of those images into a single ICO file. Modern systems read PNG data inside an ICO, so no extra conversion is needed.

Input is a PNG, ideally square and transparent. The ICO can include the standard icon sizes 16, 32, 48, 64, 128, and 256 pixels, and one ICO file holds several of them so the icon stays sharp wherever it appears. ICO is read by browsers for favicons and by Windows.

ICO is meant for favicons and Windows icons, not a full brand or export system. Sizes are capped at 256 pixels, and non-square images are centered and scaled to fit, which can leave transparent padding. Files up to 10MB are supported.

Your PNG is resized and packed into the ICO entirely in your browser. Nothing is uploaded or stored, so your logo or icon never leaves your device.
