strawberry

A Mac-only rotation-based compression tool for (potentially) superior compression compared to other tools' default implementations.

Usage

First make strawberry.sh executable by running:

chmod +x strawberry.sh

Next, run strawberry on your image. The tool creates a newly compressed image, leaving the input image unmodified.

./strawberry.sh <input.jpg>

Seeing image quality

The quality of the jpeg can be determined using ImageMagick like so:

identify -format "%Q" <input.jpg>

Compared to other tools

ImageMagick

magick <input.jpg> -quality 93 <output-magick.jpg>

sips

sips -s formatOptions 75 <input.jpg> --out <output-sips.jpg>
