JPG to BMP Converter
How to Convert JPG to BMP
Click Browse Files or drag & drop your JPG images onto the converter above. You can select multiple files for batch conversion.
Set the compression quality using the slider — higher values preserve more detail, lower values produce smaller files. Optionally enable resizing to change the output dimensions.
Click Convert to BMP and your files will be processed instantly in your browser. Download them individually or all at once.
All image conversions happen 100% in your browser. Your files are never uploaded to any server — completely private, free, and unlimited.
Why Convert JPG to BMP?
Preserve image quality for future edits — BMP uses lossless compression so you won't lose quality when saving.
BMP provides completely uncompressed image data, useful for legacy Windows applications and image processing workflows.
JPG vs BMP — Format Comparison
| Feature | JPG | BMP |
|---|---|---|
| Full Name | JPEG (Joint Photographic Experts Group) | BMP (Bitmap Image File) |
| Compression | Lossy | Uncompressed / Lossless |
| Transparency | No | No |
| Animation | No | No |
| Color Depth | 24-bit (16.7 million colors) | Up to 32-bit |
| Best For | Photographs, complex images with gradients, web images where small file size matters. | Raw image data, Windows system graphics, situations requiring zero compression. |
About the JPG Format
JPEG is the most widely used image format on the internet. It uses lossy compression, which means it reduces file size by discarding some image data that the human eye is unlikely to notice. This makes JPEG ideal for photographs and complex images with many color variations. However, each time you save a JPEG, it loses a small amount of quality — this is known as generation loss. JPEG does not support transparency or animation.
The JPEG format was created in 1992 by the Joint Photographic Experts Group. It quickly became the standard for digital photography and web images due to its efficient compression and universal browser support.
Advantages
- Extremely small file sizes for photos
- Universal support across all devices and browsers
- Adjustable compression quality
- Ideal for photographs and complex images
Disadvantages
- Lossy compression — quality degrades with each save
- No transparency support
- No animation support
- Not ideal for text, line art, or sharp edges
About the BMP Format
BMP (Bitmap) is an uncompressed image format native to Windows operating systems. Because it stores raw pixel data without any compression, BMP files are extremely large but preserve every single pixel with absolute fidelity. BMP is rarely used on the web due to its massive file sizes, but it remains relevant in Windows system graphics, legacy software, and scenarios where you need completely uncompressed image data for processing.
The BMP format was introduced by Microsoft in the early days of Windows as the native image format for the operating system. While it has been largely superseded by more efficient formats, it remains supported across virtually all image viewing and editing software.
Advantages
- Zero quality loss — completely uncompressed
- Universal support on Windows systems
- Simple format — easy to read and write programmatically
- No patent or licensing restrictions
Disadvantages
- Extremely large file sizes
- No compression means impractical for web use
- No transparency support
- No animation support
- Inefficient storage compared to PNG or WebP
