MPOViewer

View, animate, and export MPO stereo photos in Side-by-Side, Anaglyph, Wiggle, and Depth 3D modes, with decorative frames and captions.

MPO Viewer opens your stereoscopic 3D photos straight from the camera. There is no conversion step, and you do not need a computer.

If you own a dual-lens 3D camera, such as a Fujifilm FinePix REAL 3D W1 or W3, your photos are saved as .mpo files: one file holding two images, one for each eye. MPO Viewer reads both images out of the file and lets you view, animate, and export them in five 3D viewing modes on your iPhone.

BROWSING AND VIEWING Point MPO Viewer at any folder of .mpo files, on your device or in iCloud Drive, and browse them in a searchable grid or table. Open any photo in the viewing mode that suits you:

• Side by Side: the classic stereo pair, for free-viewing or for a stereo viewer or headset • Crossed Eye: the same pair, swapped for cross-eyed free-viewing • Red/Cyan Anaglyph: both images merged into one for red/cyan glasses, with channel swapping and zoom-stable disparity correction • Wiggle: the two images flicker back and forth to fake depth, either on a timer or as you tilt your phone • Depth (experimental): MPO Viewer builds a depth map from the stereo pair and warps it as you tilt the phone, for a parallax effect

Every mode supports pinch-to-zoom and pan.

FRAMES, CAPTIONS, AND SLIDESHOWS Frame your photos with a plain border or a decorative passepartout in Viewmaster or Underwood style, add a focus helper to align your eyes, and attach a caption to any photo. Run a slideshow through a folder at your own pace.

SHARE AND EXPORT Export Side by Side, Crossed Eye, and Red/Cyan composites as PNG or JPEG. Turn Wiggle mode into an animated GIF or a cross-faded video. Export Depth mode as an MP4 tilt-sweep video. You can include your GPS location in exports if you want to. Exports carry a watermark by default, and MPO Viewer Pro removes it.

PRIVACY MPO Viewer works entirely offline. Your photos never leave your device. There are no accounts, no analytics, and no data collection.

AVAILABLE IN ENGLISH AND DUTCH Switch languages from Settings without restarting the app.

MPO Viewer is built for anyone rediscovering a box of old stereo camera photos, and for anyone still shooting 3D today.
