Why Convert BMP to JPEG?
Converting BMP to JPEG massively reduces file size by applying lossy compression. Ideal for photographs stored as BMP that need to be shared or uploaded.
Common Use Cases
- Shrinking BMP photos for sharing and uploading
- Email-friendly image conversion
- Freeing up storage from large BMP collections
Source Format
BMP
Bitmap Image File
BMP is an uncompressed raster image format native to Windows. It stores pixel data directly without compression, resulting in large file sizes but perfect quality.
+ No compression means zero quality loss
+ Simple format, easy to read and write programmatically
+ Native Windows support
- Extremely large file sizes
- No transparency support
Target Format
JPEG
Joint Photographic Experts Group
JPEG is the most widely used lossy image format, optimized for photographs and complex images with smooth color transitions. It achieves excellent compression ratios at the cost of some quality loss.
+ Excellent compression for photographs
+ Universally supported everywhere
+ Adjustable quality-to-size ratio
- Lossy compression degrades quality with each save
- No transparency support
Quality & Size Notes
JPEG compression is lossy. Use quality 85-90 for photographs. BMP files are very large, so you'll see dramatic size reductions — often 95% or more.
Frequently Asked Questions
How much smaller will my BMP be as JPEG?
Dramatically smaller — typically 90-98% reduction. A 10MB BMP photo might become 200-500KB as JPEG.
Will I lose quality?
Some, since JPEG is lossy. At quality 85-90, the difference is usually imperceptible for photographs.
Why is BMP so much larger than JPEG?
BMP stores every pixel's color data without any compression. JPEG discards visual information the human eye doesn't easily notice.
