photo viewer
and sorter for Mac

review photos and play video and audio in Gallery, with keyboard playback controls

Grid lays out photos like a contact sheet, with decisions, stars, and color labels on each photo

review your Apple Photos library or an album without exporting it. iCloud downloads are optional, and albums change only when you choose Add to Album

drop another folder while reviewing. Louppe saves your decisions before switching and keeps the window size

common camera RAW files, JPEG, JPEG XL (.jxl), TIFF, PNG, HEIC, WebP, and AVIF are supported. optionally group matching RAW+JPEG files as one review item, with separate decisions, stars, and color labels

see recorded Fuji film simulations in Info and filter by simulation, including ACROS and monochrome variants. show one look from a bracketed series without changing hidden photos' decisions

How to cull RAW + JPEG pairs on Mac

read text, Markdown, and structured files alongside your media. text previews are read-only, with selectable text and clickable web and email links

inspect at 100%, use the floating control for Fit and 30–400% zoom, or try a phone-sized preview. check the histogram and clipping

in Fit and Phone size, a loading indicator shows when the photo preview is still loading. wait for it to finish before judging focus

filter by optional quality cues for high ISO, slow shutter speeds, and near-white or near-black areas. adjust their rules in Settings; pause background checks in Filter

find exact duplicates and likely similar photos locally. Filter → Capture bursts groups photos by capture time; set the interval in Settings. analysis never changes ratings or files automatically

browse an archive’s folder tree in Gallery or Grid, and move between folders with [ and ]. pin archives on Welcome to reopen them with cached previews

filter by decisions, stars, labels, dates, folders, camera details, and file types. decisions save automatically for your next session

recover saved decisions after files change. verified identical copies and returning originals recover automatically; File → Check Saved Decisions lets you review other recovery options

Organize Source Folder previews folders before moving files. Rename Files lets you reorder filename parts and use dates in your Mac's preferred format. names are previewed, extensions stay unchanged, and recognised RAW+JPEG/XMP families stay together. both actions support undo during the open session

export copies by default. you can also choose Move on the same drive, route copies to multiple folders, or write XMP sidecars for compatible editing apps

marking no does not trash a file. Clean Up is a separate action that sends unwanted files to the macOS Trash. undo is available during the open session while the files remain in Trash

Louppe processes your media locally, with no account or app analytics. all features are free, and the app is open source under the MIT License. optional tips unlock nothing

review with the keyboard or VoiceOver. customize review keys and supported Command aliases in Settings. use physical key positions for layouts such as Dvorak, or follow your keyboard layout
