How it works

Drop in photos, arrange them freely on an endless board, and keep working at any zoom level. Download a .cosref backup any time to keep your own copy, and reopen it here later.

Hundreds of photos, no slowdown

Drop in large batches of reference photos — only what's on screen is ever decoded at full size.

Pan, zoom, arrange

An endless board you can pan and zoom freely — move, resize, and rotate photos exactly where you want them.

Private by default

Your photos stay in this browser unless you choose to save them online.

Float your references over any app

Pin the board in its own always-on-top window next to your drawing or modeling program. Experimental, and currently only in Chrome, Edge, Opera and other Chromium-based browsers on a computer.
