What Hacker News says
6 sourcesJPEGLI = A small JPEG
The suffix -li is used in Swiss German dialects. It forms a diminutive of the root word, by adding -li to the end of the root word to convey the smallness of the object and to convey a sense of intimacy or endearment.
This obviously comes out of Google Zürich.
Other notable Google projects using Swiss German:
https://github.com/google/gipfeli high-speed compression
Gipfeli = Croissant
https://github.com/google/guetzli perceptual JPEG encoder
Guetzli = Cookie

Weggli = Bread roll
https://github.com/google/brotli lossless compression
Brötli = Small bread
