The important questions, plus the nearby routes users usually need next.
BMP was once the raw material for Windows icons, but a bare bitmap is not an icon file — Windows and browsers want a real .ico container with multiple embedded sizes. FileMorf renders your BMP at the standard 16-256px icon sizes and packs them into one PNG-compressed .ico. Since BMP has no transparency, the icon will be fully opaque; a square source produces the cleanest result.
Only in the padding. BMP images carry no alpha channel, so the artwork itself stays opaque — and if it is not square, the space added to square it off is transparent. For an icon with a fully transparent background, start from a PNG version of the graphic instead.
FileMorf embeds the standard icon sizes — 16, 32, 48, 64, 128, and 256 pixels — up to your source image's own size, each stored as a PNG inside the .ico container. Browsers and Windows then pick the crispest match for wherever the icon appears: browser tabs, bookmarks, taskbars, or desktop shortcuts. Start from a source of 256px or larger to get the full set.
Yes. FileMorf writes PNG-compressed ICO, the modern variant supported by every current browser and by Windows since Vista. Drop it in your site root as favicon.ico or reference it with a <link rel="icon"> tag.
Icons are square by definition, so non-square images are scaled to fit and centered on a transparent square canvas — nothing is cropped or stretched. For the cleanest favicon, start from a roughly square logo or mark.
