ExOptimizer.Optimizers.JpegOptim (ExOptimizer v0.1.1) View Source

JpegOptim is a tool to optimize JPEG files

The following options are used by default:

• -m85: this will store the image with 85% quality. This setting seems to satisfy Google's Pagespeed compression rules
• --strip-all: this strips out all text information such as comments and EXIF data
• --all-progressive: this will make sure the resulting image is a progressive one, meaning it can be downloaded using multiple passes of progressively higher details.
