Why QuickView?

Speed First

We believe tools should be instantaneous. No loading spinners, no "Indexing Library" delays. Just your images.

Privacy Native

100% Offline. No cloud sync, no AI scanning, no telemetry sharing. Your photos stay on your disk.

Zero Bloat

No database, no "Library Management". Just a pure, unadulterated file viewer that respects your file system.
