Turn BMP images into ICO: drop one or many and each is converted at once, ready to save alone or in a ZIP. Choose 16–48 px icons for a website or up to 256 px for Windows. Everything runs in your browser, so your images are never uploaded; it's free and needs no sign-up.
BMP stores pixels without compression, so its files are very large. ICO is what websites use for favicons and Windows for icons.
