Convert PNG to BMP
What is PNG?
PNG
PNG uses lossless Deflate compression, preserving exact pixel values without quality loss. Supports full alpha channel transparency (256 levels) unlike JPG. Ideal for graphics with sharp edges, text, logos, or images requiring transparency. Typically larger file sizes than JPG for photographs due to lossless compression. Maximum resolution 2,147,483,647×2,147,483,647 pixels. Supports indexed color palettes and metadata chunks.
- PNG uses lossless compression for perfect quality image storage
- Alpha channel transparency requires background color for BMP conversion
- DEFLATE compression reduces file size without data loss
- Supports 24-bit RGB color (16.7 million colors)
- Universal browser and device support—no compatibility concerns
What is BMP?
BMP
BMP (Bitmap) stores uncompressed raster images as raw pixel data with optional RLE compression. Developed by Microsoft. Simple structure: header, color palette (for indexed colors), and pixel array. No compression in standard form results in large file sizes. Supports 1-bit to 32-bit color depths. Maximum resolution 65,535×65,535 pixels. Lossless quality but inefficient storage. Limited web use due to size.
- BMP uses lossless compression for perfect quality image storage
- Opaque image data converts to PNG without utilizing transparency features
- No transparency support—requires opaque backgrounds
