Google is thinking about a new way to compress the JPEG format in order to put him smaller and with the same quality.
In research published Thursday, the technology called "Guetzli " cuts JPEG file sizes by 35% in its testing.
The idea isn't to replace the known JPEG, but minimize the size without problems of image squeezed.
The average web loaded 1mb 5 years ago to about 2.5MB today, according to the HTTP Archive.
Google developed a test called "Butteraugli " designed to model human vision.
"Butteraugli takes into account ... properties of vision that most JPEG encoders do not make use of " Google researchers said in a Guetzli research paper (PDF).
The software was released and can be used for free but the problem right now it's the speed of compressing images:
"Guetzli is rather slow to encode (...) we hope that it can show direction for future image format design "
