With this parem do not write JFIF APP0 marker segment. Reduce size in 18 bytes. This is a mandatory marker, but no error in know programs if are lost. Safe for web use.
Mozilla JPEG Encoder Project
MozJPEG reduces file sizes of JPEG images while retaining quality and compatibility with the vast majority of the world's deployed decoders.
MozJPEG is based on libjpeg-turbo. It's compatible with libjpeg API and ABI, and can be used as a drop-in replacement for libjpeg. MozJPEG makes tradeoffs that are intended to benefit Web use cases and focuses solely on improving encoding, so it's best used as part of a Web encoding workflow.
MozJPEG is meant to be used as a library in graphics programs and image processing tools. We include a demo cjpeg tool, but it's not intended for serious use. We encourage authors of graphics programs to use MozJPEG's C API instead.
Features
- Progressive encoding with "jpegrescan" optimization. It can be applied to any JPEG file (with
jpegtran) to losslessly reduce file size. - Trellis quantization. When converting other formats to JPEG it maximizes quality/filesize ratio.
- Comes with new quantization table presets, e.g. tuned for high-resolution displays.
- Fully compatible with all web browsers.
- Can be seamlessly integrated into any program using libjpeg.
