About BMP
BMP
BMP (Bitmap) is a simple, largely uncompressed raster image format native to Windows. BMP stores pixel data with optional Run-Length Encoding, making it trivial to read and write, but produces very large files. It remains useful as an intermediate, loss-free working format.

Frequently Asked Questions
What is a BMP file?▼
BMP (Bitmap) is one of the oldest Windows image formats. It stores pixels uncompressed, so files are large but open instantly on any Windows machine.
Why should I convert BMP to PNG or JPG?▼
BMP files are huge compared to modern formats. Converting to PNG keeps the exact pixels at a fraction of the size; JPG shrinks photos even further for sharing.
Does BMP support transparency?▼
Not reliably. While 32-bit BMP variants can carry an alpha channel, support is inconsistent across apps. If you need transparency, convert to PNG.
Is BMP still used today?▼
Mostly in legacy Windows apps and some embedded systems. For anything modern — web, sharing, editing — PNG or JPG are better choices.
Will converting BMP lose image data?▼
Converting to PNG is fully lossless. Converting to JPG discards a small amount of detail in exchange for dramatically smaller files.
