About:
Viso is a lightweight, native image viewer for macOS designed for speed and simplicity. It supports a wide range of image formats and provides essential tools for viewing, organizing, and making quick edits. Its value proposition is delivering a fast, distraction-free viewing experience without the overhead of complex photo management suites.
Key Features:
  • Broad format support including RAW and PSD
  • Lightning-fast performance for large images
  • Batch processing and renaming capabilities
  • Minimalist, native macOS user interface
Use Cases:
  • Quickly browsing large folders of images without importing them into a library
  • Reviewing RAW photos from a camera or drone
  • Batch resizing or converting images for web or documents
Alternatives:
  • Preview – Built-in and free, but lacks advanced batch processing and speed for large files
  • XnView MP – Cross-platform and powerful, but has a less native macOS feel and a more complex interface
