What is BMP Format?

BMP (Bitmap Image File) is a raster graphics image format developed by Microsoft. It stores images in an uncompressed format, preserving every pixel's exact color information. This makes BMP files larger than compressed formats like JPG, but ensures no quality loss through compression artifacts.

Key Characteristics of BMP Files:

• Lossless Quality: No compression artifacts or quality degradation
• Wide Compatibility: Native support in Windows and most image editors
• Simple Structure: Easy to read and process programmatically
• True Color Support: Supports up to 16.7 million colors (24-bit)
• Alpha Channel: Optional transparency support in 32-bit BMP files

Why Convert JPG to BMP?

1. Preserve Image Quality

When you need pixel-perfect accuracy, BMP's uncompressed format ensures no data is lost. This is essential for:

• Technical documentation
• Medical imaging archives
• Print-ready graphics
• Software development assets

2. Legacy Software Compatibility

Many older Windows applications and specialized software require BMP format:

• Industrial control systems
• Embedded systems displays
• Legacy publishing software
• Certain CAD applications

3. Simple Image Processing

BMP files are easier to manipulate programmatically due to their straightforward structure:

• Pixel-by-pixel editing
• Color analysis
• Image comparison
• Batch processing operations

Frequently Asked Questions

Is this converter free?

Yes! Our JPG to BMP converter is completely free with no usage limits or sign-up required.

Are my images secure?

Absolutely. All conversions happen locally in your browser. Your images are never uploaded to any server, ensuring complete privacy.

Why are BMP files so large?

BMP files are uncompressed, storing every pixel's color value directly. A 1000×1000 pixel image at 24-bit color requires about 3MB (1000×1000×3 bytes) plus a small header.

Can I convert multiple images at once?

Currently, the converter processes one image at a time. For multiple images, convert them sequentially.

What's the maximum file size supported?

You can convert images up to 20MB in size. Larger images may slow down your browser.

Will the image quality change during conversion?

No quality is lost during conversion. BMP maintains the exact pixel values from your original image.

Do BMP files support transparency?

Standard 24-bit BMP files don't support transparency. For transparency, consider using 32-bit BMP or PNG format.

Which browsers are supported?

Our converter works in all modern browsers including Chrome, Firefox, Safari, and Edge.
