Frequently Asked Questions
Which icon size gets converted?
This tool automatically finds and converts the largest image stored within the .ico file. ICO files often contain multiple sizes (like 16x16, 32x32, 256x256), and using the largest one ensures the highest possible quality for your BMP.
What happens if my icon is transparent?
Since the BMP format does not support transparency, any transparent areas in your icon will be filled with a solid white background to ensure a clean, usable image.
Why is the final BMP file larger than the ICO?
ICO files use compression (often containing a PNG inside) to keep file sizes small. BMP is an uncompressed format that stores data for every pixel, resulting in much larger files. This conversion is for compatibility and raw data access, not for file size reduction.
