The image-js organization on GitHub was created in June 2015 in the group of Luc Patiny at EPFL. It provides image processing and analysis in JavaScript, for the browser and Node.js, together with pure-JavaScript image decoders and encoders (PNG, TIFF, JPEG, BMP) and a library to read and write binary data.
It contains 20 public repositories and 13 packages published on npm, downloaded 104,160,033 times in September 2026 and 684,288,159 times in the last 12 months (October 2025 to September 2026). Many of these packages are currently maintained by Zakodium Sàrl.
