JPG vs BMP Format Comparison

Aspect JPG (Source Format) BMP (Target Format)
Format Overview
JPG
Joint Photographic Experts Group

Compressed image format widely used for photographs and web images with lossy compression.

Standard
BMP
Bitmap Image File

Uncompressed or lightly compressed raster image format used primarily in Windows systems.

Legacy
Compression

Lossy compression using DCT algorithm, significantly reducing file size with quality trade-offs.

Typically uncompressed or uses simple RLE compression, preserving all original pixel data.

Color Depth

24-bit RGB color (16.7 million colors) with 8 bits per channel, no transparency support.

Variable: 1, 4, 8, 16, 24, or 32 bits per pixel with optional alpha channel support.

File Size

Small to medium files (10 KB - 5 MB) depending on compression quality and image content.

Very large files (100 KB - 100+ MB) due to uncompressed or minimal compression.

Image Quality

Good quality with adjustable compression levels, some artifacts in high compression.

Perfect pixel-accurate quality with no compression artifacts or data loss.

Advantages
  • Small file sizes with good quality
  • Universal support across all platforms
  • Adjustable compression quality
  • Excellent for photographs and complex images
  • Perfect image quality with no compression loss
  • Simple format structure
  • Supports various color depths and transparency
  • Fast loading and processing
Disadvantages
  • Lossy compression reduces image quality
  • No transparency support
  • Compression artifacts in detailed areas
  • Not suitable for images with sharp edges
  • Extremely large file sizes
  • Limited web browser support
  • Inefficient for storage and transmission
  • Outdated format with limited modern use
Use Cases
  • Web images and photography
  • Social media and digital sharing
  • Email attachments
  • Digital cameras and smartphones
  • Legacy Windows applications
  • Simple graphics and icons
  • Image processing workflows
  • Screen captures and system graphics
Tooling & Ecosystem
  • All modern image editors and viewers
  • Web browsers and mobile apps
  • Digital cameras and photo software
  • Windows Paint and basic editors
  • Legacy Windows applications
  • Image processing libraries
Browser Support

Excellent universal support across all web browsers and platforms.

Limited browser support; mainly requires download or plugin for viewing.

Transparency

No transparency support; background colors are always solid.

Optional alpha channel support in 32-bit BMP files for transparency effects.

Metadata Support

Extensive EXIF metadata support for camera settings, GPS, and image information.

Minimal metadata support; basic image properties only.

Loading Performance

Fast loading due to small file sizes and efficient compression algorithms.

Slow loading due to large uncompressed file sizes, especially over networks.

Why Convert JPG to BMP?

Converting JPG to BMP is useful when you need to eliminate compression artifacts and preserve perfect image quality for further processing or editing. BMP format stores images without any compression loss, making it ideal for professional image editing workflows, legacy Windows applications, or situations where pixel-perfect accuracy is required. This conversion is particularly valuable when working with images that will undergo multiple editing cycles, creating master copies for archival purposes, or when integrating with older software that specifically requires BMP format. While BMP files are significantly larger, they provide the foundation for high-quality image manipulation without the quality degradation inherent in JPG's lossy compression.
