More than a viewer:
choose and organize.
AuroraViewer connects browsing, comparison, ratings, tags, inspection, and export while preserving the source location of your files. These capabilities reflect the current source and version 1.6.3.
Browse
Bring sources into one library
Open individual images, multiple folders and their subfolders, plus images inside ZIP, RAR, and 7z as source groups. Finder opening and drag and drop are supported.
- Add images, folders, and archives together
- Collapse, expand, and reorder groups
- Skip hidden items and duplicate URLs
Search, sort, and narrow the library
Search names and extensions, then sort by capture or modified date, size, resolution, rating, and more. Filters can be combined.

Review
Keep decisions beside the originals
Record 0–5 stars and Pick/Reject status, then read and write Finder tags. Apply them to a selection or the current filtered results.
- Keyboard-first ratings
- Create, apply, and remove Finder tags
- Undo recent Aurora operations
Compare
Place candidates side by side
Arrange images in two, three, or four slots and synchronize zoom and pan. For comics and scans, use two-page viewing with right-to-left ordering when needed.
- Drag-and-drop slot placement
- Independent or synchronized transforms
- Animation playback and slideshows
Inspect
Look closer at color and capture data
Magnify the pixel under the pointer and read RGB, HEX, and HSB values. Use the EXIF overlay for camera and capture information.
- Color Picker and pixel preview
- Histogram and channel views
- Edit selected EXIF fields in JPEG, TIFF, and HEIC
Organize
Group duplicate and similar images
Find exact duplicates by file hash, or group visually similar images with perceptual hashes and Apple Vision. Nothing is deleted automatically.
- All, selection, or filtered-result scope
- Adjustable similarity threshold
- Review a suggested keeper in each group
Export
Prepare files for the next task
Convert the current image, or copy and move selected originals. Choose crop, dimensions, quality, and metadata handling for the intended result.
- PNG, JPEG, TIFF, HEIC, and WebP
- Original size, 5–300% scaling, or explicit width and height
- Keep, remove location, or strip metadata
