Why is BMP so large? What is the BMP format?

BMP (Bitmap) is an uncompressed image format developed by Microsoft. Unlike JPG (which compresses data), BMP stores every single pixel's colour value without any compression. A 1920×1080 BMP photo takes approximately 6MB of disk space. The same image as a JPG at 90% quality is typically 300-500KB — a 90-95% reduction. BMP is a legacy format that was common in older Windows applications but is rarely needed today.

When is BMP used and why convert to JPG?

BMP files are common in: Windows desktop wallpapers (legacy), screenshots from older Windows versions, images exported from CAD and industrial software, and fax images. Converting to JPG offers massive file size savings, universal sharing compatibility, and is far more suitable for email, web, and storage purposes.

Frequently asked questions

Why is my BMP file so large? ▾
BMP is uncompressed — it stores raw pixel data without any compression algorithms. A 1920×1080 24-bit BMP is exactly 5.9MB by definition: 1920 × 1080 × 3 bytes per pixel. JPG's compression reduces this dramatically while maintaining excellent visual quality.
Is there quality loss when converting BMP to JPG? ▾
At 90% quality, the visual quality difference is typically imperceptible. JPG's compression is particularly effective for photographic images. For line art or diagrams with sharp edges, consider converting to PNG instead of JPG to better preserve sharp transitions.
Is my BMP file uploaded to a server? ▾
No. All processing happens in your browser. Even large BMP files are processed locally — nothing is sent to any server.
