How to view Ricoh Theta 360° photos in a browser
Ricoh Theta cameras stitch photos in-camera, so every JPEG they save is already a ready-to-view 360° image. Copy the file off the camera, open it in the free viewer, and you are looking around it. No app, no account.
Theta files are already 360°-ready
Unlike Insta360 or GoPro cameras, a Theta stitches its two fisheye lenses inside the camera and writes a standard equirectangular JPEG with the XMP 360° metadata that Facebook, Google Photos and viewers look for. The only exception is raw: the Theta Z1 can also save DNG files that need stitching in Lightroom with Ricoh's Theta Stitcher plug-in.
- Theta X: 60 MP, 11008×5504 JPEG (also 5.5K mode at 5504×2752).
- Theta Z1: 23 MP, 6720×3360 JPEG; optional DNG raw.
- Theta SC2 / V / S / SC: 14 MP, 5376×2688 JPEG.
Get the photo off the camera
- USB (computer): connect the Theta; it mounts as a drive (or as a camera device on Windows, where the photos are under DCIM). Copy the JPEGs.
- Theta app (phone): connect to the camera's Wi-Fi, open the photo and tap Save to camera roll. The saved file is the same full-resolution JPEG.
- Theta X: has a microSD slot, so the card can go straight into a reader.
- Wi-Fi to computer: the camera hosts a small web server; power users can pull files from http://192.168.1.1/osc/… with the Open Spherical Camera API.
View it in the browser
- Open the free 360° viewer in Chrome, Edge, Safari or Firefox.
- Drag the Theta JPEG onto the page, or press Choose a 360° photo and pick it (on a phone, from the camera roll).
- Click and drag, or swipe, to look around; scroll or pinch to zoom; press Fullscreen for an edge-to-edge view.
- On a phone, tap Gyro to look around by moving the device, or VR for Cardboard mode. On a headset, VR opens an immersive session.
Everything stays on your device: the JPEG is decoded in the browser and is never uploaded, so it is safe for pre-release property listings, insurance documentation and client work. A Theta X photo at 11008 pixels wide is downscaled on phones and older laptops to fit the GPU; desktops show it at full detail.
Troubleshooting
- Photo is tilted: the Theta writes gyro data but applies it only when "top/bottom correction" is enabled in the camera or the app. Re-save the photo from the Theta app with correction on, or level it in Theta software.
- Blurry seam: subjects closer than about 60 cm to the lenses cannot be stitched cleanly; keep the camera away from walls and hands.
- DNG will not open: browsers cannot decode raw. Stitch and export a JPEG from Lightroom with the Theta Stitcher plug-in first.
- Looks like a wide, warped strip in Windows Photos: that is the normal equirectangular layout; use a 360° viewer.
- Stereo (3D) toggle turns on by itself: only square images are treated as stereo; a Theta JPEG is 2:1 and should open in mono. If not, press 3D top/bottom to switch it off.
Frequently asked questions
Do I need the Ricoh Theta app to view Theta photos?
No. Theta JPEGs are standard equirectangular images and open directly in the free browser viewer on this site, or in any 360° viewer, without the app or a Ricoh account.
How do I view a Theta 360° photo on Windows or Mac?
Copy the JPEG from the camera by USB and open it in free360viewer.com in any browser. Windows Photos and macOS Preview show it as a flat, stretched strip; a 360° viewer shows it as a sphere you can look around.
Can I view Theta photos in a VR headset?
Yes. Host the photo at a public link, open it in the headset browser (Meta Quest, Pico) on free360viewer.com and press VR. On a phone, VR switches to Google Cardboard split-screen mode.
Can this viewer play Theta 360° videos?
No, it is a photo viewer. Theta videos need converting in the Theta app and play in 360° video players such as YouTube.
