Why convert ICO to BMP?
ICO is the Windows icon container that bundles one or more small images used for favicons and application icons. BMP is an uncompressed raster format that stores raw pixel data, yielding large but universally readable files.
BMP does not support transparency, so any transparent areas in your ICO are flattened onto a solid white background. BMP is lossless, so quality is preserved perfectly; expect the file to be larger than a compressed ICO. BMP is readable by virtually all legacy Windows software.
Pixohub converts ICO to BMP entirely inside your browser using the HTML canvas API, so your images are never uploaded to a server. That makes conversion instant, completely private, and free — turn as many ICO files into BMP as you like. Reach for BMP whenever you need maximum compatibility with legacy Windows software and raw, lossless pixels.
ICO vs BMP: what to expect
ICO is best for favicons and Windows desktop icons, while BMP shines for maximum compatibility with legacy Windows software and raw, lossless pixels. Keep your original ICO if you may later need its transparency, and export a BMP copy for compatibility and editing.
