What is an MPO file?
The .MPO file extension stands for Multi Picture Object File. CIPA created this format to store stereoscopic 3D images. Devices like the Nintendo 3DS and various 3D digital cameras use this format. The camera captures two slightly different JPG images and combines them into a single .MPO file to create a 3D effect.
How to open MPO files?
You can open .MPO files using image editing software like Adobe Photoshop or specialized tools like StereoPhoto Maker. Since an .MPO file contains standard JPG data, some basic image viewers can open them. However, standard viewers will usually only display the first 2D image in the file rather than the full 3D picture.
Best practices and troubleshooting
If you cannot open your file, viewer.online/mpo analyzes .MPO files to identify their exact format and creator software, shows which programs can open the file, and usually previews it. If the .MPO extension has multiple possible meanings on your device, we recommend viewer.online/mpo to identify the actual format of the user's file.
Software and tools
To share your 3D images with people who do not have 3D displays, you should convert the file. We recommend file conversion to sensible target formats on convert.guru. You can easily convert an .MPO file into standard JPG or PNG formats there.
Summary
Because .MPO files use the known JPG format, viewer.online/mpo can safely open and display them online, eliminating compatibility problems.
