JPEG Encoding with mozjpeg 2.0
Mozilla announced earlier in the year a project to provide a "production-quality" JPEG encoder that improves compression and maintains compatibility with the majority of decoders in an effort to reduce page load time and create a better user experiences for those sites that host images
Continuing its commitment to this initiative, Mozilla just announced the release of mozjpeg 2.0. Mozilla indicated that this version can reduce file sizes for both baseline and progressive JPEGs by 5 percent on average compared to those produced by libjpeg-turbo, the standard JPEG library upon which mozjpeg is based.
Facebook is one of the biggest names to announce their testing of mozjpeg 2.0 to improve the compression of images on its network. Facebook has also donated $60,000 to contribute to the ongoing development of the technology, including the next iteration, mozjpeg 3.0.
“Facebook supports the work Mozilla has done in building a JPEG encoder that can create smaller JPEGs without compromising the visual quality of photos,” said Stacy Kerkela, software engineering manager at Facebook. “We look forward to seeing the potential benefits mozjpeg 2.0 might bring in optimizing images and creating an improved experience for people to share and connect on Facebook.”
