Hi, I definitely agree that it shouldn't replace the current library (especially considering the performance, didn't think it would be that slow). I think the nicest way would be a checkbox or a dropdown in the jpeg export section. Nils Von: Heiko Bauke Gesendet: Freitag, 17. März 2017 19:43 A

According to https://github.com/google/guetzli: Introduction Guetzli is a JPEG encoder that aims for excellent compression density at high visual quality. Guetzli-generated images are typically 20-30% smaller than images of equivalent quality generated by libjpeg. Guetzli generates only sequentia

Hi! Yesterday Google announced Guetzli, a jpeg encoder producing better results than libjpeg as can be read here: https://research.googleblog.com/2017/03/announcing-guetzli-new-open-source-jpeg.html Code is available on Github: https://github.com/google/guetzli/ Wouldn't that be a nice thing
