The Lightbox window: folders in the sidebar and a wall of images

Your images stay exactly where they are.

Only the folders you choose

Add the folders you care about, group them in the sidebar and keep favorites at the top. Lightbox never goes looking through the rest of your disk.

Nothing is imported

No library to build and no copies to keep in step. You see the same files Finder shows you, with far less empty space around them.

Pictures, not chrome

Images fill the window edge to edge in tidy rows, complete and uncropped. One slider makes them bigger or smaller.

Take a closer look

Open any image to see it in full quality. The arrow keys move through the folder, and the next pictures are already loading before you get there.

Two versions of an image compared with a draggable divider

Compare two

Pick two images and flip between them in place, or drag a divider across to see exactly what changed.

An image being split into four pieces

Split a picture

Cut one image into several separate files, for example a sheet with four pictures on it. The lines snap to the middle, and you decide what happens to the original.

  • Ssplit

Stars, favorites, sorting and the rest are on the features page.

Lightbox asking before it moves an image to the Trash

Careful with your files.

  • It asks first. Deleting an image or a folder and renaming a folder wait for your OK. Splitting a picture does too, unless you turn that question off.
  • The Trash, wherever there is one. On a drive without a Trash, Lightbox asks a second time before deleting for good.
  • Nothing happens on its own. Lightbox changes a file only through an action you pick. Never as a side effect, and never after an error.
  • Its own files stay out of the way. Thumbnails live in a hidden .thumbnails folder beside your images.

Quick, even on a network drive

Thumbnails are made once and kept next to your images, so a folder you have opened before shows up almost at once.

Keeps track for you

Rename or move a folder in Finder and Lightbox follows it. Folders on a drive that isn't connected wait, dimmed, until it's back.

Updates find you

When a new version is ready, Lightbox shows what's new and installs it with one click.
