libjpeg-turbo vs MozJPEG

libjpeg-turbo is a JPEG image codec that uses SIMD instructions to accelerate baseline JPEG compression and decompression on x86, x86-64, ARM, and PowerPC systems. It is faster than libjpeg and provides API/ABI compatibility with it.

MozJPEG is an image compression tool that optimizes JPEG files with improved compression ratios while maintaining compatibility with standard JPEG decoders. It is useful for reducing image file sizes for websites.
