PNG to ICO Favicon Converter

Convert a PNG image into a multi-size .ico favicon file. Modern browsers prefer separate PNG / SVG favicons, but a multi-size .ico still wins for legacy compatibility (older Windows clients, some email clients, RSS readers). Bundles standard favicon sizes (16, 32, 48 for browser tabs; 64, 128, 256 for higher-DPI displays and pinned shortcuts).

How to use the PNG to ICO Favicon Converter

Upload a square PNG, preferably 256×256 or larger. Pick which sizes to bundle (16/32/48 cover most needs; add 64/128/256 for retina and pinned shortcuts). Click Generate, then Download. Save as favicon.ico in your site root.

Why a multi-size .ico still matters

Favicons have largely moved to PNG and SVG, but the classic favicon.ico still earns its place: it is the format legacy Windows clients, some email clients, and a number of RSS readers reach for first. And because an ICO can hold several resolutions in one file, the browser picks the crispest size for each context — a tab, a bookmark, a pinned shortcut.

This converter takes one PNG and bundles the sizes you choose (16, 32, 48 for tabs; 64, 128, 256 for high-DPI and shortcuts) into a single .ico. Start from a square PNG of 256×256 or larger for the sharpest result. Need the source resized first? Use the image compressor to downscale it.

Common use cases

• Favicon creation — produce a favicon.ico from a logo PNG.
• Legacy support — cover older browsers and clients that expect ICO.
• Multi-resolution — bundle several sizes so each context looks sharp.
• Pinned shortcuts — include large sizes for desktop and taskbar icons.
• Quick rebrand — regenerate a favicon after a logo change.
