ICO to BMP Conversion
ICO is a file format specifically designed for computer icons in Microsoft Windows. An ICO file can contain multiple images at different sizes and color depths, allowing the icon to scale appropriately across the interface.
BMP (Bitmap) is an uncompressed raster image format. It stores color data for every pixel without any compression, resulting in very large file sizes. While it offers high quality, its large size makes it impractical for web use.
Frequently Asked Questions
Converting Windows ICO (Microsoft's modern icon format with compression and multi-resolution support) to primitive BMP (1986 uncompressed format) is a downgrade in almost every way - you lose multi-resolution embedding and gain enormous file sizes.
Converting ICO to BMP extracts a single resolution as an uncompressed bitmap. File sizes will be larger than the original ICO in most cases. This conversion only makes sense for extremely specific legacy scenarios: vintage DOS applications that somehow need icon artwork as BMP, certain industrial systems with hardcoded BMP requirements, or very specific technical workflows. For virtually all modern use cases, convert ICO to PNG instead - you get better quality, transparency preservation, smaller file sizes, and universal compatibility. ICO to BMP is rarely the right choice.
