BMP vs ICO: Understanding the Difference

BMP (Bitmap Image File)

BMP is a raster graphics format that stores images without compression, resulting in large file sizes but perfect quality preservation.

•Transparency: No

•Animation: No

•Since: 1986

ICO (Icon File Format)

ICO is a special image format designed for icons in Windows applications and website favicons, capable of storing multiple sizes in a single file.

•Compression: varies

•Transparency: Yes

•Animation: No

•Since: 1985

Converting from uncompressed Bitmap Image File to Icon File Format will significantly reduce file size while maintaining good visual quality.

Icon File Format supports transparency, but since Bitmap Image File doesn't include transparency data, your converted image will have a solid background.

•printing when file size doesn't matter

When to use ICO:

•website favicons
•Windows application icons
