Extremely Fast Lossless Image Compression

QB3: Image/Raster Compression, Fast and Efficient - Better compression than PNG in most cases - Lossless compression and decompression rate of 500MB/sec for byte data, 4GB/sec for 64 bit data - All integer types, signed and unsigned, 8 to 64bit per value - Lossless, or lossy by division with a small integer (quanta) - No significant memory footprint during encoding or decoding - No external dependencies, very low complexity
