ICO vs BMP Format Comparison

Aspect	ICO (Source Format)	BMP (Target Format)
Format Overview	ICO Windows Icon Container for one or more small images at multiple resolutions and color depths. Standard	BMP Bitmap Image File Uncompressed raster format native to Windows; simple pixel map storage. Standard
Compression	Typically uncompressed or RLE-compressed variants; small images limit size.	Uncompressed or RLE; results in larger file sizes proportional to resolution.
Color Depth	Supports 1, 4, 8, 24 or 32-bit images per icon entry.	1, 4, 8, 16, 24 or 32 bits per pixel; no alpha in some variants.
File Size	Very small for icons (typically a few KB); grows with higher resolutions.	Large due to lack of compression; size increases with bit depth and resolution.
Advantages	Multi-resolution support Integrated in Windows shortcuts and executables Small sizes for interface icons	Universal OS support Exact pixel representation Simple file structure
Disadvantages	Limited to small image sizes No full alpha in older formats Not suitable for high-resolution photos	Huge file sizes for large images No built-in transparency in basic BMP Not optimized for icons
Use Cases	Application and desktop icons Favicons and UI elements Multi-resolution icon sets	Raw image dumps Pixel-accurate editing Legacy Windows applications
Tooling & Ecosystem	Icon editors (IcoFX, Greenfish Icon Editor) Visual Studio, resource compilers Windows Explorer	Paint, GIMP, Photoshop ImageMagick, GraphicsMagick Most OS-native viewers

Why Convert ICO to BMP?

ICO files are optimized for small, multi-resolution icons but aren’t suitable for general-purpose image editing or printing. Converting to BMP gives you a full-size, pixel-perfect raster file that can be opened and edited by a wide range of graphics software.

BMP’s simple, uncompressed structure ensures every pixel is preserved exactly, making it ideal for tasks where accuracy is critical—such as manual retouching or analysis. It also removes the constraints of icon-size limits, allowing you to work with the full resolution image.

Whether you need to extract an icon for use in a document, integrate into legacy systems, or perform detailed pixel work, converting ICO to BMP unlocks universal compatibility and maximum image fidelity.
