macOS Quick Actions

Three macOS Automator workflows that add right-click context menu options in Finder for converting images to modern web formats. Download from GitHub.

  • Save as AVIF - Convert images to AVIF format using npx
  • Save as WEBP - Convert images to WebP format with quality 85
  • Tinify - Compress PNG/JPG/JPEG images using TinyPNG API

Each one is an Automator .workflow file that takes image files as input — double-click to install and it shows up under Quick Actions in the Finder's right-click menu. Underneath they're shell scripts: AVIF runs through npx, WebP through cwebp from Homebrew's webp, and Tinify posts to the TinyPNG API, which needs a free API key and jq to read the response back. Converted files land next to the original, with Tinify appending _compressed. Built with Claude.
