About:
Pngyu is a user-friendly GUI wrapper for the powerful pngquant command-line tool. It enables rapid lossy compression of PNG images, significantly reducing file sizes while preserving visual quality. The application provides a simple drag-and-drop interface for batch processing images without needing to use the terminal.
Key Features:
  • Drag-and-drop batch processing
  • Visual quality vs. file size comparison
  • Lossy compression via pngquant engine
  • Simple, native macOS interface
Use Cases:
  • Optimizing web graphics for faster page loads
  • Reducing asset sizes for mobile app development
  • Batch compressing screenshots and images for sharing
Alternatives:
  • ImageOptim – More comprehensive tool supporting multiple optimizers and formats, but Pngyu is specifically focused on pngquant's lossy compression.
  • pngquant (CLI) – The command-line tool Pngyu wraps; offers more granular control but lacks a GUI.
