Why Convert BMP to JPG?
BMP (Bitmap) is an uncompressed raster format that stores every pixel's raw color data, producing extremely large files. A simple 12-megapixel photo can be 36 MB as BMP but only 2-3 MB as JPEG. Converting BMP to JPG is one of the most impactful file size reductions you can achieve: typically 90-95% smaller files with minimal visible quality loss. BMP files are impractical for web use, email attachments, cloud storage, and most modern workflows. They were common in early Windows applications but have been superseded by more efficient formats. If you have a collection of BMP files from an older camera, scanner, or legacy software, batch converting to JPG will reclaim enormous amounts of storage space while making the images far easier to share and use.
BMP vs JPG Comparison
BMP stores pixels as raw uncompressed data with zero quality loss but produces enormous files. JPG uses sophisticated lossy compression algorithms to discard imperceptible visual data, reducing files to a fraction of the original size. A 4000x3000 BMP weighs exactly 36 MB while the same image as JPG at 85% quality might be 1-2 MB. BMP supports 1-bit through 32-bit color depth with no compression artifacts. JPG supports 24-bit color with adjustable compression and is universally supported across every device and platform. There is virtually no scenario today where BMP is preferable to JPG for photographs. The only use case for BMP is specialized software that requires raw pixel access, which is increasingly rare.
