Lyn 2.4.9

Lyn 2.4.9 for Mac

Lyn is a lightweight photo browser, viewer, and non-destructive editor for macOS, aimed at photographers, designers, and anyone who needs to sift through large folders quickly. It opens JPEG, PNG, TIFF, HEIC, HDR, JPEG XL, AVIF, SVG, RAW from major cameras, plus QuickTime video and simple PDF preview.

Browse and organize

Four configurable browser views, fullscreen slideshows, smart folders, keywords, ratings, and color tags help you narrow huge shoots. Inspect and edit IPTC metadata, geotag on a map with drag-and-drop, and browse libraries from Photos, Lightroom, and older Aperture/iPhoto archives. Soft-proofing and color profiles keep previews accurate for print-minded workflows.

• Non-destructive adjustments stored as attributes and applied on export
• Editing inspector: exposure, curves, levels, B&W, sepia, vignette, HDR, film grain, and more
• Share to Flickr, Dropbox, and SmugMug
• Optimized for Apple Silicon; vendor lists macOS Sequoia and Tahoe as ready
