Browse the folder
A grid of thumbnails you can rate, filter and select, decoded as they scroll into view.
Shortcuts are written the macOS way — on Windows and Linux, read Cmd as Ctrl. Press ? inside the app for the list as your own machine shows it.
The library is a grid of thumbnails, decoded as they scroll into view, so a folder of several thousand photos is browsable in seconds instead of loading everything up front. Everything below happens with the grid in front of you — you never have to open a photo to rate it.
Rate as you go
With a photo highlighted, press 0 to 5 to set the star rating, Shift+1 through Shift+5 for a color label (red, yellow, green, blue, purple), and Shift+0 to clear it. The Rating and Label tabs on the right do the same with the mouse.
Build a selection
Click to select, Shift+click to take a range, Cmd+click to toggle a single photo, and Cmd+A to take the whole folder. The arrow keys move the highlight; Shift+arrows extend the selection. A selection is what batch settings and export act on.
