Free online ICO→BMP converter. Fast, private, no sign-up.
Need to turn a ICO file into a BMP file? This converter does it in seconds and downloads the result automatically. Drop in your ICO file (a .ico) and download a ready-to-use BMP file (a .bmp) — no software to install, no account to create, and no watermark on the output.
ICO is the Windows icon format — it packs several small sizes into one file and is what browsers request as a favicon.
BMP is an uncompressed Windows bitmap — large files because nothing is compressed, but dead simple and universally readable on Windows.
Most people convert ICO to BMP for compatibility — a website, app or device insists on BMP, and ICO simply won't open. BMP is widely supported, which makes it a dependable target. Under the hood the conversion runs on libvips and ImageMagick — the same libraries that power image pipelines across the web — so colour, transparency and metadata are handled correctly wherever the target format supports them.
BMP has no alpha channel, so any transparent areas in your ICO are flattened onto a solid background during conversion.
It comes up when publishing online, submitting to a service with strict format rules, or archiving a collection in a single consistent format.
Privacy is the default here. Your ICO file is uploaded over an encrypted connection, converted, downloaded the moment it's ready, and then deleted automatically a short time afterwards. We never keep your files, never build a library of your content, and never make you sign up to download the result.
