Question 1

How to install ImageOptim-CLI on a Mac?

Accepted Answer

You can install it via npm with 'npm install -g imageoptim-cli', use homebrew with 'brew install imageoptim-cli', or manually download the binary and add it to your PATH. Homebrew is recommended for easy updates.

Question 2

ImageOptim-CLI vs imagemin: which is better for image optimization?

Accepted Answer

ImageOptim-CLI excels on macOS by leveraging proven GUI tools for superior compression ratios, as per benchmarks. Imagemin is cross-platform and plugin-based, offering more format flexibility but may not match the performance on PNG/JPEG files.

Question 3

Does ImageOptim-CLI support WebP images?

Accepted Answer

No, it only handles PNG and JPEG formats. The FAQ explicitly states that WebP conversion is outside its scope, so you'll need other tools for modern formats like WebP.

Question 4

How to batch optimize all images in a folder with ImageOptim-CLI?

Accepted Answer

Run 'imageoptim' followed by the directory path or file patterns (e.g., 'imageoptim ~/Desktop'). Use flags like '--imagealpha' for PNGs or '--jpegmini' for JPEGs to enable specific optimizers.

Question 5

Is JPEGmini required to use ImageOptim-CLI?

Accepted Answer

No, JPEGmini is optional and paid. You can use ImageOptim-CLI with just the free tools—ImageOptim and ImageAlpha—by omitting the '--jpegmini' flag, as mentioned in the FAQ.

Question 6

Can ImageOptim-CLI be used in a CI/CD pipeline?

Accepted Answer

Yes, it's designed for automation and can be integrated into build scripts. However, it only works on macOS runners, so you'll need to ensure your CI environment supports macOS, such as with GitHub Actions or similar services.
