Drop images

Drag files or a folder in, or choose a folder to watch. Every image becomes a card you can tick.

A graphics card with a current driver: Intel, AMD or NVIDIA, integrated graphics included

About 600 MB for the app, plus room for big files: an 8192 px JPEG is about 10–20 MB, a 16,384 px PNG several hundred MB

Windows shows a warning?

The installer is signed by Odyssean LLC. A new release can still trigger Microsoft SmartScreen until it builds a reputation: click More info, then Run anyway. We publish the installer only on our GitHub releases page.

Updates

The app checks GitHub for updates, downloads them quietly and offers a restart when one is ready. It never updates while an image is being processed. Your settings, image list and license survive updates.
