macOS command line
shiboru
A simple image optimizer for macOS. Point it at files or folders and it squeezes PNG, JPEG, GIF, SVG, and ICO assets down for the web.
It is lossless, sequential, and built for a clean Homebrew install. By default it writes optimized copies beside your originals.
Formats
Supports PNG, JPEG, GIF, SVG, and ICO.
How it fits
- Works well before shipping assets
- Good for icons, screenshots, logos, and static site media
- Designed for local developer workflows
Usage
Typical commands for single files, folders, and in-place replacement.
