Complete Guide: ICO to BMP Converter
Everything you need to know about using this tool effectively
The ICO to BMP Converter transforms ICO icon files into uncompressed BMP bitmap images. ICO stores one or more small images at different sizes, and the tool extracts the largest available size and exports it as a BMP file. The tool processes everything in the browser, so your image never leaves your device.
This tool reads your ICO file, extracts the largest icon image, renders it to a canvas, and exports it as BMP format. BMP does not support transparency, so any alpha channel in the ICO will be flattened against a solid background.
Edit favicons as bitmaps
Convert ICO files to BMP for editing in image editors that do not support ICO format directly.
Legacy software compatibility
Extract ICO icons as BMP files for use in older applications that require bitmap input.
Icon analysis
Convert ICO files to BMP to examine pixel data at full resolution without compression artifacts.
Embedded systems
Export ICO icons as BMP for use in hardware and embedded systems that need raw pixel data.
Upload an image
Drag and drop or click to browse for your ICO file.
Convert
Click Convert. The tool extracts the largest icon and generates a BMP file.
Download
Save the converted BMP image to your device.
The tool extracts the largest size from the ICO file for maximum detail.
BMP is uncompressed, so the output file will be larger than the ICO source.
ICO transparency is not preserved in BMP format.
ICO files often contain multiple sizes. The largest available size is used for the conversion.
Will the quality change?
No. BMP is uncompressed, so the pixel data from the ICO is preserved exactly. The output resolution depends on the largest size in the ICO file.
Is my image uploaded to a server?
No. All processing happens in your browser using the Canvas API. The image never leaves your device.
Which icon size is extracted?
The tool extracts the largest available size from the ICO file for the best possible resolution.
Does BMP support transparency?
No. Transparent pixels in the ICO will be flattened against a solid background color.
Can I convert multiple images at once?
Yes. Upload multiple files and the tool converts all of them.
