Features

• Browse photos by location

  Shift+L opens Location Map for your loaded collection. Explore recorded GPS locations, open nearby photo groups and return to the same map position. Pan, zoom and navigate by keyboard, with light and dark map styles. OpenStreetMap tiles need an internet connection.

• Similarity Explorer

  Shift+S groups visually related photos into stacks. Filter by 75 subjects and scenes, adjust the grouping and save reusable presets. Available on supported macOS, Linux and Windows 11 systems. After an optional first-use model download, image analysis runs locally and works offline — your images are never uploaded.

• Find more photos like this

  Choose a reference image and press Cmd/Ctrl+Shift+L to find up to 30 similar pictures in your loaded collection. Browse the matches, compare your picks and save selected results to Favorites. Uses the same local analysis as Similarity Explorer.

• Compare every detail

  Compare two images side by side or overlay them with a movable swipe divider. Link zoom and pan to inspect the same detail in both, adjust each image independently and swap sides.

• Copy just the part you need

  Opt/Alt+Shift+C starts Copy Selection. Draw a rectangle, move or resize it, then copy that image region as PNG pixels at its own resolution. Paste it into another app without changing the original image.

• Export a copy to share

  Export PNG or JPEG copies with an optional longest-edge limit of 2400, 1600 or 1000 pixels. Leave camera, capture-date and GPS metadata out of JPEG copies while keeping the original untouched.

• Picture-frame mode

  P turns your collection into a full-screen slideshow with crossfades. Adjust the timing with the up and down arrows, or use Shift+P to shuffle the order.

• Drop almost anything

  JPEG, PNG, GIF, WebP, BMP, TIFF, ICO, XPM, SVG, AVIF and camera RAW (embedded JPEG preview). HEIC/HEIF opens with a compatible system decoder; Settings includes a support check and installation instructions. AVIF support is built in.

• Keyboard browsing

  Step through a set with the arrow keys (wrapping at both ends), or jump straight to the ends with Home and End.

• Thumbnail grid

  G opens a full-window grid for finding an image by sight. Thumbnails load lazily, so a folder of several thousand files stays responsive.

• Mosaic generator

  Turn your Grid View selection — or the current filtered grid when nothing is selected — into a display-sized image mosaic. Choose Random or Shelf layout, tune frames, overlap and shadows, then regenerate, save it as PNG or JPEG, or set it as wallpaper.

• Zoom and pan

  + − 1 0, or scroll to zoom at the cursor. Click-drag or Shift+scroll to pan once zoomed in.

• Animated GIFs

  Played back frame by frame at their encoded speed, composited correctly per frame so partial updates never leave stale pixels.

• EXIF aware

  JPEGs auto-rotate to their orientation tag, and E shows camera, lens, exposure, aperture, ISO, capture date and coordinates — plus a collapsible OpenStreetMap view pinned at the spot a GPS-tagged photo was taken, collapsed until you ask for it.

• Sorting that makes sense

  Natural name order by default, so IMG_2 comes before IMG_10. S cycles through capture date, modified time, size and raw drop order.

• Folders and merging

  Drop folders to scan them recursively, with a live counter for large trees. M makes further drops add to the set instead of replacing it.

• Named favorites

  Save the current file list as a collection and reopen it from the Favorites menu after a restart. The first ten are one shortcut away with Cmd/Ctrl+1–9 and Cmd/Ctrl+0.

• Hide duplicate images

  Browse large quantities of images with ease by hiding duplicates and filtering out noise. d and Shift+D (to show duplicate variants).
