JPEG has been in the market for quite a long time and it has been
showing no signs of disappearing. It is the only lossy compression
format which has achieved universal compatibility across all the
browsers and software that can display images. That is the reason why
Mozilla has announced a new project called mozjpeg, which promises to
reduce the file size by up to 10% and aims to compress images more
intelligently. The goal of this project is to provide a
production-quality JPEG encoder that improves compression rates.
However, the company wants to continue compatibility with the majority
of deployed decoders.
According to a report, since HTML, CSS, JS files are relatively smaller, Mozilla points out that images make up for the bulk of network traffic for a web page to load. Smaller the file size faster will the web pages load. Moreover, JPEG has been ruling the image compression format across the globe since 1992, so the company wants to reduce the size of these files for optimization and reduce load on the network. Therefore, Mozilla feels that optimization of the compression format is worth trying, even with search on for a better successor.
This will be challenging for libjpeg-turbo, an existing open-source toolthat is used to create JPEGs. Mozjpeg version 1.0 comes with ‘jpgcrush’ functionality added, that picks the best compression options without sacrificing the image quality. Mozilla has conducted tests shows that the encoder squeezes 10 percent off a sample of 1,500 images on Wikimedia. Further, mozjpeg can also compress PNG file sizes by 2 to 6 percent. Google has also tried to improve the web speed by including a variety of new graphics format like WebP but so far Mozilla does not use WebP. The mozjpeg software is now at version 1.0 but more updates are likely to be added- Trellis quantization being one of them.
