BMP vs JPEG Format Comparison

Aspect BMP (Source Format) JPEG (Target Format)
Format Overview
BMP
Bitmap Image File

Uncompressed raster image format developed by Microsoft; stores pixel data directly.

Standard
JPEG
Joint Photographic Experts Group

Lossy compressed format widely used for photographs, balancing quality and file size.

Standard
Compression

No compression; stores full bitmap data.

Lossy DCT compression; adjustable quality vs file size.

Color Depth

1 to 24 bits per pixel, depending on variant.

8 bits per channel (24-bit color).

File Size

Very large; uncompressed data size proportional to resolution and color depth.

Moderate; depends on quality setting and resolution.

Why Convert BMP to JPEG?

Converting BMP images to JPEG drastically reduces file size, making images easier to store, share, and load on web pages. While BMP stores raw pixel data without compression, JPEG applies lossy compression that balances image quality with file size savings, ideal for everyday photographs and web use.

Additionally, JPEG is universally supported across devices, browsers, and software, ensuring maximum compatibility. By converting to JPEG, you streamline your workflow, improve performance, and reduce bandwidth usage without significant perceptible loss in visual quality.
