PDF to BMP: Raw Pixel DataUncompressed format for pixel-perfect editing
BMP stores raw, uncompressed pixel data—what you see is exactly what's stored in memory. Perfect for image processing, legacy Windows software, and scenarios requiring pixel-level control.

Why Choose BMP Format
BMP offers uncompressed pixel access and Windows native integration for specialized workflows
Zero compression = zero quality loss
BMP stores every pixel exactly as rendered without any compression algorithm. No JPEG artifacts, no PNG encoding overhead. Pure, unmodified pixel data. What the screen displays is what the file contains byte-for-byte.
Windows native format
BMP is Windows' original bitmap format. Old Windows software (Win95, WinXP apps) handles BMP natively without codec dependencies. Legacy industrial software, medical equipment, and embedded Windows systems default to BMP.
Pixel-level editing foundation
Image processing algorithms work directly on BMP's raw pixels. Computer vision, pattern recognition, and pixel manipulation scripts prefer BMP's simple structure. No need to decode compressed data before processing.
Simple file structure
BMP headers are straightforward—width, height, color depth, then raw pixel array. Easy to parse programmatically. Writing custom BMP readers/writers takes hours, not weeks. Educational tool for learning image formats.
Guaranteed color accuracy
No color space conversions, no subsampling tricks. RGB values stored as-is. Medical imaging, scientific visualization, and color-critical applications rely on BMP's literal pixel representation.
Direct memory mapping
BMP pixel data maps directly to framebuffer memory. Hardware accelerators and graphics drivers load BMP files with minimal processing. Embedded systems and real-time applications benefit from BMP's simplicity.

Common Use Cases for BMP
These scenarios leverage BMP's uncompressed pixels and Windows native support
Image processing and computer vision
OpenCV, MATLAB, and Python image libraries read BMP directly without decompression overhead. Training machine learning models on uncompressed data. Academic research avoiding compression artifacts in results.
Legacy Windows software compatibility
Old manufacturing control software, industrial automation tools, and vintage Windows applications expect BMP. Factory floor systems running WinXP can't handle modern formats. BMP ensures compatibility back to Windows 3.1.
Medical imaging raw data
Radiology equipment, microscopy analysis, and diagnostic software use BMP for uncompressed medical images. No compression means no diagnostic information loss. Regulatory compliance requires exact pixel preservation.
Game development texture source
Game engines convert BMP textures to optimized formats during build. BMP serves as uncompressed source material for asset pipelines. Artists save work as BMP before automatic compression into DDS or KTX.
Embedded system displays
Industrial touch screens, kiosk displays, and embedded Windows CE devices use BMP for UI graphics. Simple BMP decoders fit in limited ROM. Real-time systems load BMPs with predictable timing.
Pixel art and sprite sheets
Pixel artists preserve exact colors in BMP before engine conversion. Sprite editors (Aseprite alternatives) export uncompressed BMPs. No compression means no color palette corruption in indexed-color artwork.
PDF to BMP FAQ
Why use uncompressed BMP despite large file sizes?
BMP's lack of compression means zero quality degradation and instant pixel access. Image processing algorithms, medical equipment, and computer vision applications need raw pixel data without decoding overhead. The larger file size is acceptable when processing speed and pixel accuracy matter more than storage.
What's the difference between BMP and PNG?
PNG uses lossless compression to reduce file size while BMP stores raw pixels. BMP files are 3-5x larger but simpler to parse programmatically. PNG is better for web use and storage. BMP excels in legacy Windows software, real-time systems, and workflows requiring direct memory mapping without decompression.
When should I choose BMP over compressed formats?
Use BMP for legacy Windows software compatibility (Win95, WinXP apps), image processing pipelines that need raw pixel arrays, embedded systems with simple decoders, or when you need guaranteed pixel-for-pixel accuracy without any compression artifacts. For web sharing or storage, use PNG or JPG instead.
Does BMP work on Mac and Linux systems?
Yes. While BMP is Windows' native format, modern Mac and Linux systems support BMP viewing and editing. However, BMP is less common on these platforms where PNG and JPG are preferred. BMP's simplicity ensures compatibility but file size makes it impractical for everyday use outside Windows ecosystems.
Why are BMP files so much larger than JPG or PNG?
BMP stores every pixel's RGB values directly without compression algorithms. A 1920×1080 BMP image contains 2,073,600 pixels × 3 bytes (RGB) = 6.2MB minimum. JPG compresses this to 200-500KB by discarding data. PNG reduces to 1-2MB using lossless compression. BMP trades file size for processing simplicity and zero quality loss.
Is BMP suitable for web use or only desktop applications?
BMP is unsuitable for web use due to large file sizes causing slow page loads and poor SEO. Browsers support BMP but convert internally, wasting bandwidth. BMP belongs in desktop workflows: image processing, legacy Windows software, scientific instruments, and embedded systems where simplicity outweighs file size concerns.
