arith

Background

arith began as a CLI image compressor / decompressor that my friend Toby and I built in C¹ for a college class.

I subsequently ported the C code over to JavaScript so it could run on the web!

About arith

arith takes in a .ppm image file and compresses it by as much as 60%. It also supports decompressing arith-compressed .ppm images.

Understandably, ppm is not a common format for storing images, but there are many tools online that can convert jpg / png images into ppm files, such as this one that is also linked on the website, so feel free to play around with your own images!
