Convert ICO to BMP
What is ICO?
ICO
ICO stores multiple bitmap images at various sizes and color depths (1-bit to 32-bit with alpha) in a single file. Designed for Windows application and website favicons. Contains multiple representations (16×16, 32×32, 48×48, 256×256) for different display contexts. Can store both BMP and PNG formats internally. Maximum 256×256 pixels per image. Supports transparency.
- ICO uses lossless compression for perfect quality image storage
- No transparency support—requires opaque backgrounds
What is BMP?
BMP
BMP (Bitmap) stores uncompressed raster images as raw pixel data with optional RLE compression. Developed by Microsoft. Simple structure: header, color palette (for indexed colors), and pixel array. No compression in standard form results in large file sizes. Supports 1-bit to 32-bit color depths. Maximum resolution 65,535×65,535 pixels. Lossless quality but inefficient storage. Limited web use due to size.
