⚖️ Technical Format Comparison: PNG vs BMP
Detailed side-by-side analysis of compression algorithms, color depth, transparency, and file size impact
| Technical Specification | PNG (Source) | BMP (Target) |
|---|---|---|
| Full Format Name | Portable Network Graphics | Bitmap Image File (Microsoft Windows) |
| MIME Type | image/png | image/bmp |
| Compression Method | Lossless (DEFLATE / LZ77 + Huffman) | Uncompressed (Raw RGB Raster Grid or RLE) |
| Color Space & Bit Depth | 24-bit RGB + 8-bit Alpha (TrueColor 16.7M + 256 Alpha Levels) | 1-bit to 32-bit (typically 24-bit TrueColor) |
| Alpha Transparency | Yes (Full 8-bit Alpha Channel Transparency) | No (Standard 24-bit BMP has no alpha channel) |
| Animation Support | No (APNG supported in niche apps) | No (Static Single Frame) |
| Typical File Size | Medium to Large (preserves exact pixel perfection) | Very Heavy (Full uncompressed byte-for-byte pixel array) |
| Ideal Applications | Transparent logos, UI icons, screenshots, digital artwork, graphic overlays | Raw uncompressed raster storage, legacy Windows apps, hardware displays |
💡 Conversion Impact Summary:
Decompresses DEFLATE PNG streams into uncompressed 24-bit TrueColor BMP raster arrays.
