FAQPage Schema
How do I batch compress images to WebP or PNG from the command line?▼

Batch compress images by running the CLI on a directory to automatically select the best available tool and output WebP or PNG files with optional quality settings.

What image formats are supported for automatic optimization?▼

Image optimization supports WebP, PNG, and JPEG formats, automatically detecting and applying the best tool to reduce file size for each input.

Do I need Node.js and the sharp package to compress images?▼

Yes, compressing images requires Node.js and the sharp package, though the tool also detects and uses system tools like sips, cwebp, or ImageMagick when available.

What's the best way to convert images to WebP on macOS?▼

Convert images to WebP by running the CLI, which automatically selects sips on macOS or falls back to cwebp, ImageMagick, or sharp based on availability.

Can I get JSON output summaries after batch processing a directory?▼

Yes, batch processing a directory can output human-readable progress or JSON summaries detailing the image compression results and file size reductions.

Why does image compression fail when system tools are missing?▼

Image compression fails without Node.js and sharp if no system tools are detected; the CLI requires at least one available tool among sips, cwebp, ImageMagick, or sharp to process images.
