BMP
BMP (Bitmap) is an uncompressed raster image format developed by Microsoft. BMP files store raw pixel data without any compression. A single 1920×1080 BMP image is approximately 6 MB. BMP is the native format of Windows Paint and Windows screenshots on older systems.
JPG
JPG reduces file size by 80–95% compared to BMP while maintaining acceptable visual quality. JPG uses DCT-based lossy compression optimized for photographic content. Every device, browser, and application supports JPG. It is the standard web and sharing format.

Convert BMP to JPG to dramatically reduce file size. An uncompressed 6 MB BMP becomes a 300 KB–1 MB JPG. Share images via email within attachment size limits. Upload to websites and social media that reject BMP format. Free storage space by converting BMP collections.
Câu Hỏi Thường Gặp (FAQ)
How much smaller will the JPG be compared to BMP?
JPG files are 80–95% smaller than equivalent BMP files. A 6 MB BMP (1920×1080) converts to approximately 300 KB–1 MB JPG at high quality. The compression ratio depends on image complexity.
Is BMP the same as bitmap?
Yes. BMP stands for Bitmap Image File. It stores raw, uncompressed pixel data. Every pixel is recorded individually, resulting in very large file sizes. BMP is a Microsoft format native to Windows.
Will I lose quality converting BMP to JPG?
Minimal quality loss at high quality settings (80–95%). BMP is uncompressed, so the JPG conversion introduces the first compression. At quality 90%, the visual difference is imperceptible for photographs.
Does BMP support transparency?
Standard BMP does not support transparency. 32-bit BMP variants include an alpha channel, but this is rarely used. Converting to JPG removes any alpha channel data.
Where do BMP files come from?
Windows Paint saves as BMP by default on older Windows versions. Some scanners output BMP. Medical imaging, industrial cameras, and legacy software may produce BMP files. Windows clipboard paste operations create BMP data.
