Adjust per-eye width/depth, enhance video quality, convert 2D to 3D, or convert VR video to SBS — all in your browser.

Adjust per-eye width/depth, enhance video quality, convert 2D to 3D, or convert VR video to SBS — all in your browser. Five tools in one extension, all running entirely on your device — nothing uploaded, nothing sent to a server: Per-Eye Width/Depth Adjustment Watching side-by-side (SBS) 3D video through 3D glasses? Correct two common issues live, while you watch: • Width — corrects horizontal stretch so faces and objects look natural, not stretched. • Depth — zooms in to fill more of your glasses' display and reduce black borders. 2D → 3D (Beta) Turn an ordinary 2D video into a real-time side-by-side 3D image, right on the page. Works best when the camera or scene motion is relatively steady. VR to SBS Have a VR/360° video with its own drag-to-look viewer? Converts it into a standard side-by-side 3D video, viewable with ordinary 3D glasses right in the same panel. The panel recognizes VR video automatically and switches to this mode on its own — no setting to find. 3D SBS → 2D Already have a 3D side-by-side video but want to watch it normally? Instantly flattens it back into an ordinary 2D video — handy without glasses, or on a display that isn't 3D-capable. Higher Quality Makes blurry or low-quality video look noticeably sharper and more detailed, in real time, at the exact size you're already watching it. Smooth, responsive playback across all five tools — including on Windows laptops with both integrated and dedicated graphics. How to use: 1. Fullscreen the video (or make it render large on the page). 2. The adjustment panel appears automatically, centered over the video. 3. Pick a mode — No effect, 2D → 3D, VR to SBS (auto-selected for recognized VR video), or 3D → 2D — and optionally turn on Higher Quality. 4. Drag Width/Depth (or Look dir./FOV in VR to SBS) to taste, or press Reset to return to defaults. 5. Click ✕ to close — playback keeps going, uninterrupted. 100% local — nothing is collected, stored, or transmitted. No account required.
