Generate uncompressed BMP (Bitmap) sample images for testing, embedded systems, and legacy applications. BMP preserves exact pixel data without compression artifacts.
What is BMP?
BMP (Bitmap Image File) is an uncompressed raster image format developed by Microsoft. It stores images pixel-by-pixel without lossy compression, resulting in larger file sizes but perfect pixel accuracy. BMP supports various bit depths from 1-bit monochrome to 32-bit with alpha.
Why Use BMP?
Uncompressed format preserves exact pixel data without artifacts
Direct memory mapping for embedded systems and displays
No decoding overhead - pixels are stored in raw format
Universal support on Windows and most imaging software
Ideal for testing image processing algorithms with predictable data
Common Use Cases
Embedded Systems
Direct display on LCD/OLED screens without decompression. BMP can be memory-mapped directly to framebuffers.
Image Processing Testing
Test image algorithms with uncompressed source data where compression artifacts would affect results.
Legacy Software Compatibility
Support older Windows applications and systems that require native BMP format.
Print Proofing
Generate exact-resolution test images for print calibration and verification.

Frequently Asked Questions
Why are BMP files so large?
BMP files are uncompressed, storing each pixel individually. A 24-bit BMP uses 3 bytes per pixel, so a 1920×1080 image requires about 6MB. This ensures pixel-perfect quality but results in large files compared to compressed formats like PNG or JPEG.
When should I use BMP instead of PNG or JPEG?
Use BMP when you need raw pixel access (embedded systems), testing image algorithms, or working with legacy software. For web and general use, PNG or JPEG are better choices due to smaller file sizes.
Does BMP support transparency?
32-bit BMP includes an alpha channel for transparency, but support varies by application. PNG is generally preferred for transparent images due to better compatibility.
What bit depth should I choose?
24-bit is standard for full color (16.7 million colors, 3 bytes/pixel). Choose 32-bit if you need alpha channel transparency. Both provide true color quality.
Can I use BMP for web pages?
While browsers support BMP, it is not recommended for web use due to large file sizes. Use WebP, PNG, or JPEG instead. BMP is better suited for offline, embedded, or testing applications.
