Why Convert ICO to BMP?
Converting ICO to BMP extracts the icon into a simple bitmap format. Since ICO internally uses BMP-like storage, this is a straightforward extraction.
Common Use Cases
- Extracting icon pixel data for legacy systems
- Simple image processing from icon files
- Windows application compatibility
Source Format
ICO
Icon File Format
ICO is the standard icon format for Windows applications and website favicons. It can store multiple image sizes in a single file, typically up to 256x256 pixels.
+ Standard format for favicons and Windows icons
+ Stores multiple resolutions in one file
+ Transparency support
- Maximum size of 256x256 pixels
- Limited to icon use cases
Target Format
BMP
Bitmap Image File
BMP is an uncompressed raster image format native to Windows. It stores pixel data directly without compression, resulting in large file sizes but perfect quality.
+ No compression means zero quality loss
+ Simple format, easy to read and write programmatically
+ Native Windows support
- Extremely large file sizes
- No transparency support
Quality & Size Notes
ICO and BMP share similar pixel storage. No quality is lost. Transparency is not preserved in BMP.
Frequently Asked Questions
Are ICO and BMP related?
Yes, ICO files internally use BMP-like pixel storage. Converting between them is straightforward with minimal data transformation.
What happens to transparency?
BMP doesn't support transparency. Transparent areas will be filled with a white background.
Will the file size change?
BMP files may be slightly larger since they store raw pixel data without the multi-resolution ICO container.
