Progresssive JPEG export?

[tomByrer]

In some cases, PJPEGs are smaller than the on progressives.
I found some C++ code if that's helpful.

Jimp relies on https://github.com/eugeneware/jpeg-js for jpeg encoding/decoding. Progressive JPEG export would need to be added there, and then an option for progressive export would need to be added to Jimp. Would be great to have!

Have a look at imagemin. I use jimp + imagemin since a while

[strandedcity]

They rely on https://github.com/mozilla/mozjpeg, which isn't a pure-JS implementation of the JPEG encoder. Unfortunately, won't work for Jimp.

You are right, I always forget people use jimp in the browser. Just for correction: imagemin has various plugins. One of them is depending on mozjpeg. Others are guetzli, jpegtran, jpeg-recompress, jpegoptim and many pther for png or webp. They are all native code afaik, so not suitable for jimp :(
