About:
Retrobatch is a visual batch image processor for macOS that allows users to create complex workflows for manipulating large numbers of images. It provides a node-based interface to chain operations like resizing, format conversion, watermarking, and metadata editing. This tool significantly streamlines repetitive image processing tasks for photographers and designers.
Key Features:
  • Visual node-based workflow builder
  • Supports batch processing of thousands of images
  • Extensive image manipulation operations (resize, filter, watermark)
  • Non-destructive editing and workflow saving
  • Direct integration with macOS Photos app
Use Cases:
  • Resizing and watermarking a batch of photos for a portfolio website
  • Converting a folder of images from RAW to JPEG format
  • Automating the addition of copyright metadata to exported images
Alternatives:
  • ImageMagick – Command-line based, more powerful for scripting but lacks a GUI
  • Photoshop Actions – Requires Adobe subscription and is less specialized for batch workflows
