Fast, beautiful photo browsing
Only for Mac
Free · In‑App Purchases
Mac
New in 1.7: Places maps your trips, Highlights picks your best shots, Clean Up clears copies and blurry photos, and quick edits are built in.
Lumen is a fast, focused photo viewer for people who keep photos in folders.
Open any folder and browse instantly: a folder tree in the sidebar, a clean grid, a filmstrip, and a distraction-free viewer that mounts each photo on a warm paper mat. No importing, no library lock-in - your folders stay exactly as they are.
EVERYTHING, FREE FOR 7 DAYS:
- Smart search: describe a photo in your own words, like "people on a beach" or "dinner with friends", and Lumen finds it across all your folders. It runs on an on-device model (a one-time 656 MB download), so your photos never leave your Mac and it works offline. It also finds the words visible inside photos, places and dates. Right-click any photo for Find Similar
- Places: see a folder as a trip on a map, stop by stop, with each stop's photos beside it
- Highlights: the best 20, 30 or 50 photos of a folder on a day-by-day timeline, ready to play or export
- On This Day: photos from today's date in earlier years, on Lumen Home
- Select many at once: drag across photos like in Finder, then move, copy, rotate, rate, share or trash them together
- Opens 25+ formats: JPEG, PNG, HEIC, WebP, AVIF, JPEG XL, GIF, TIFF, PSD, and RAW (DNG, CR2, NEF, ARW, RAF)
- Cull fast: pick, reject, star and colour-label with one key (P, X, 1-5), filter to your picks, then move the rejects to the Trash or copy the keepers to a folder. Marks are saved as XMP sidecars that Lightroom, Capture One and Bridge read, and RAW+JPEG pairs share them
- Compare two photos side by side, zoomed together, and keep the better one
- Clean Up: finds copies, the weaker shots of each burst, blurry photos and screenshots in a folder, and Best Shot picks the keeper of every burst. Nothing goes until you choose
- Folder-first browsing: a folder tree in the sidebar, whole folders of folders in one grid, and four layouts: tiles, squares, whole photos and a sortable list
- Edge-to-edge fullscreen, zoom to pixels, rotate and flip
- Quick edits: Auto Enhance plus Light, Contrast, Warmth, Colour and Sharpen, crop and auto-straighten, remove background, and edit a photo's date, place and keywords. Save as JPEG, PNG, HEIC or TIFF, or under a file size you choose
- Batch convert, resize and rename any number of photos, with optional EXIF and location stripping
- Cinematic slideshow: Ken Burns motion, shuffle, speed control
- Present mode: chrome-free viewing on AirPlay, HDMI and Sidecar displays
- Live Text: select and copy text inside photos
- Animated GIF playback with frame stepping
- Copy, paste, duplicate, rename, and trash with undo - no Finder round trips
- EXIF info panel with histogram and location map
- Live folder watching: changes in Finder appear instantly
- No account. Your photos never leave your Mac.
