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.

Turning a transparent PNG logo into a favicon.ico
PNG is the best starting point for an icon because its transparency passes straight through: the ICO stores each size as a full-color image with an alpha channel, so a round or irregular logo sits cleanly on a browser tab or the Windows desktop. Use a square PNG of at least 256 × 256 pixels and all six sizes, from 16 up to 256, are created.
Design matters more than conversion here. At 16 × 16 pixels, wordmarks, thin strokes and small details turn into a smudge, while a bold symbol or a single letter stays readable. A long horizontal wordmark gets shrunk to fit the square and looks tiny, so crop to the symbol part of the logo first.
To use it on a site, save the download as favicon.ico in your site's root folder or reference it from the page head. Need a single size, or one file per size? The ICO converter lets you pick the embedded sizes. Phones and home screens use PNG icons rather than ICO, which the favicon generator packs alongside a web manifest.
