About BMP Converter

BMP (Bitmap) is one of the oldest image formats, developed by Microsoft. It stores pixel data uncompressed, resulting in very large file sizes. This tool converts BMP files to modern compressed formats like JPG (for photos), PNG (for transparency), or WebP (for web). You can also convert any image INTO BMP format when required by older Windows software.

Frequently Asked Questions

Why are BMP files so large?+
BMP stores every pixel's raw color data with no compression. A 1920×1080 BMP file is around 6MB, while the same image as JPG would be 200-500KB.
Which format should I convert BMP to?+
For photos: JPG (smaller file). For graphics/logos with sharp edges: PNG. For web use: WebP gives the smallest file size. BMP is only needed for some legacy Windows applications.
Does BMP support transparency?+
Standard BMP does not support transparency. If you need transparency, convert to PNG instead. Some BMP variants (32-bit) technically support alpha but have poor software support.
