File Operations

Load images, save results, run batch processing, and navigate through files in a folder.

πŸ“‚
Open Image File(s)
  • Two files selected: loaded as separate left and right images.
  • One file (Spatial Photo/MPO file): automatically detected and split into left/right views.
  • One file (standard image): divided horizontally in half and treated as SBS.
Drag and drop 1 or 2 image files directly onto the window to open them instantly.
πŸ’Ύ
Save Displayed Image
Saves the current view β€” whether SBS, anaglyph, or any other display mode β€” as an image file.
πŸ₯½
Save as Spatial Photo
Exports your work as a Spatial Photo compatible with Apple Vision Pro. Spatial-specific parameters can be fine-tuned in the save dialog.
⚑
Batch Operation
Process multiple image files at once. Convert and export large collections of stereo photos in a single operation.
🏷
Orientation Tag Edit
Edit the Exif Orientation tag of image files. Useful for correcting images that display in the wrong orientation. You can also open it as a mirror image.

File Navigation β€” PREV / NEXT
Browse images in the same folder using the β—€ PREV and NEXT β–Ά buttons. The current filename and position (e.g., 3/12) are shown below the navigation buttons. For MacOS security reasons, users must select the folder when using this feature.
