So, scale to the target dimensions first (with quality 100, and possibly other things like 4:4:4 chroma, and most certainly with dct float), then downsize the file. I am using ImageMagick to reduce the image resolution, height and width. ![]() This is because, when you display it, you ideally want the image dimensions being an integer multiple or fraction of the final display dimensions, to make scaling easier, or even unnecessary.

You can crunch them even better by running it twice, because empirically, most images are smaller as progressive: jpegoptim -s -all-progressive -S8 *.JPG jpegoptim -s -all-normal -S8 *.JPG -S8 means to target a filesize of about 8 KiB First, update your package sources: sudo apt update Then, install imagemagick: sudo apt install imagemagick If you don’t already have a sample image handy to work with, you can download the header image from this tutorial using curl, and save it as image. ![]()
