Open a folder,
see everything.
Lumen is a quiet, fast photo viewer for people who keep photos in folders. RAW from your camera, WebP from the web, screenshots, scans - a clean grid, a distraction-free viewer, and nothing to import. Your folders stay exactly as they are.
What it does
JPEG, PNG, HEIC, WebP, AVIF, JPEG XL, GIF, TIFF, PSD - and RAW straight from Canon, Nikon, Sony and Fujifilm cameras. 25+ formats, no plugins.
Subfolders appear as tiles, the path bar is clickable all the way up, and new files show up the moment they land in the folder. No library, no lock-in.
Folders open immediately and stay smooth - hold an arrow key and scrub through a whole shoot like flipping cards.
Copy, paste, duplicate, rename, and trash with undo - the things you'd bounce to Finder for, right in the viewer, with multi-select for all of them.
Auto-enhance, exposure, contrast and saturation, then export as JPEG, PNG, HEIC or TIFF - with crop, straighten, and aspect presets. Part of Lumen Pro.
Two hundred RAWs to web-ready JPEGs in one pass, with optional EXIF and location stripping for photos you share. Part of Lumen Pro.
Cinematic slideshows with Ken Burns drift, and a chrome-free Present mode for AirPlay, HDMI and Sidecar displays. Part of Lumen Pro.
Lumen makes no network connections at all. No account, no analytics, no cloud - your photos are yours, full stop.
Fair & simple
Browsing, every format, fullscreen, slideshows, file management - the core of Lumen costs nothing and never will.
Editing, batch convert, Present mode and Live Text unlock with a single purchase. No subscription, nothing to cancel, all future updates included.
No data collection of any kind. Read the privacy policy - it's three sentences long.
