Compressor.js is a JavaScript image compressor and converter originally made by Chen Fengyuan.
There鈥檚 now a modernized, optimized, and maintained fork available with Compressor.js Next鈥攃heck the demo for what it does and the docs for how you could use it.
I worked on providing Compressor.js Next after Compressor.js hadn鈥檛 been updated in three years and when I couldn鈥檛 reach Chen to confirm their plans. In line with the license, patching up the project seemed useful.
If you鈥檝e been using Compressor.js and want to upgrade, this is straightforward: Install compressorjs-next instead of compressorjs.
And that鈥檚 it鈥攋ust know that as part of the modernization, ESM is now the default module format (CommonJS is still supported), the noConflict() method has been removed, and Internet Explorer is no longer supported.
About Me
I鈥檓 Jens (long: Jens Oliver Meiert), and I鈥檓 an engineering lead, guerrilla philosopher, and indie publisher. I鈥檝e worked as a technical lead and engineering manager at various companies (e.g., Google); I鈥檓 an active web and tool developer (code optimization, digital defense), a contributor to web standards (like HTML, CSS, WCAG), and a book author (O鈥橰eilly, Frontend Dogma).
I love trying things鈥攊n web development and engineering management, but also in politics and philosophy, where I hold to one idea in particular: that we can only be well if we take good care of everyone. Here on meiert.com I talk about some of my perspectives and experiences. (Please share feedback: Interpret charitably, keep it friendly, but do be critical.)
