CropViewer thumbnail grid with a folder tree, file names under each thumbnail, and the toolbar

⚡ Built for scale

Virtualized thumbnail grid with background decoding and a two-tier cache. Thousands of images, no freezing. Each thumbnail shows the whole image with its file name.

🎯 Precision crop

The crop rectangle lives in original pixel coordinates — not screen pixels. Move, resize, rotate with sub-pixel accuracy, aspect-ratio lock, and game size presets.

🔄 Quick edits

Rotate, flip horizontally/vertically, scale by percentage, or resize to exact dimensions — all undoable.

🖼 Real viewer

Wheel zoom, pan, fit / 100%, pixel-perfect rendering, transparency checkerboard, and an immersive fullscreen mode with arrow-key navigation.

💾 Smart saving

Quick-save crops with auto-numbered names, Save As with per-format options, overwrite, and an optional /cropped folder.

📂 Opens instantly

Double-click an image in Finder and it opens straight into the viewer — decoding starts immediately while the folder loads in the background.

🛠 All the basics, built in

Every essential image-processing operation in one place — rotate left & right, flip horizontal & vertical, resize to exact dimensions, scale by percentage, and precision crop. Fully non-destructive and undoable.
