What is ICO to BMP Converter?
ICO to BMP Converter extracts an icon image and exports it as an uncompressed bitmap file. ICO files can store several icon sizes in one container, while BMP stores one raster image as pixel data. The tool reads the ICO in the browser, selects the largest available icon, renders it to canvas, and writes a BMP file.
How does ICO to BMP Converter work?
This tool parses the ICO file, extracts the largest embedded image, draws it to a browser canvas, and exports the pixels as BMP. BMP output is uncompressed and does not preserve alpha transparency. Transparent icon pixels are flattened during export.
Key Features
- Converts ICO files to BMP format
- Extracts the largest embedded icon size
- Uses browser canvas rendering for local processing
- Shows original and output file sizes
- Supports drag-and-drop file selection
- Downloads the converted BMP file
- Supports images up to 50MB
- Supports batch conversion for multiple ICO files
Common Use Cases
Edit favicons as bitmaps
Convert ICO files to BMP for editors and legacy tools that do not read icon containers.
Legacy software compatibility
Extract ICO icons as BMP files for older applications that require bitmap input.
Icon analysis
Convert ICO files to BMP to inspect the largest icon's raw pixel output.
Embedded systems
Export ICO icons as BMP for hardware and embedded systems that read bitmap pixel data.
How to Use This Tool
Upload an image
Drag and drop an ICO file or select one from your device.
Convert
Click Convert. The tool extracts the largest icon image and writes a BMP file.
Download
Save the converted BMP bitmap to your device.
Pro Tips
- 1
ICO to BMP converter output uses the largest embedded icon size for the most detail.
- 2
BMP output can be larger than the ICO source because BMP stores uncompressed pixels.
- 3
ICO transparency is flattened because standard BMP output has no alpha channel.
- 4
Use PNG instead if the extracted icon must keep transparency.
Frequently Asked Questions
What does ICO to BMP converter do?
ICO to BMP converter extracts the largest icon image from an ICO file and exports it as an uncompressed BMP bitmap.
Is my ICO uploaded to a server?
No. The ICO is decoded and rendered in the browser before the BMP file is generated.
Which icon size is extracted?
The tool extracts the largest available image from the ICO file for the best available resolution.
Does BMP support transparency?
No. Standard BMP output does not support alpha transparency, so transparent ICO pixels are flattened.
When should I convert ICO to BMP?
Convert ICO to BMP when legacy software, hardware tools, or pixel-processing workflows need bitmap input.
