PureRef was created to be a simple and lightweight tool for artists to organize and view their reference images.
You can drag-n-drop files from your computer or images directly from browsers. You can also use the right-click menu or ctrl+v to paste them. You can edit your images in a few ways to fit your reference need. You can select one or more, focus on one or more(doubleclick/space), rotate (freely or with snapping using shift), flip, scale, crop, change opacity, delete and save images.
Optimize the canvas around your images, pack your images, toggle always on top-function, toggle transparent to mouse-function, lock the canvas for editing, clear canvas.
