写真を3Dに。 深度を感じて、すぐ書き出し。
無料の写真→3Dジェネレーター。AIが端末内だけで深度を推定し、画像をインタラクティブなレリーフまたは点群として再構築。GLB・OBJ・USDZで書き出せます — アップロードも登録も不要。
平面写真から、グルッと回せる3Dへ。プライベートに。
アカウント不要、APIキー不要、クラウドレンダリング不要。深度モデルがあなたのブラウザにやってきます。
100% 端末内・プライベート
深度推定は WebGPU によりブラウザ内で動作し、WASM へ自動フォールバック。写真が端末の外に出ることはありません。

About Depth 3D
A free browser tool that turns a single photo into an interactive 3D object you can orbit, tune, and export. It is built for people who want a picture to feel more alive — a product shot for a store listing, a portrait, a plate of food, a building facade — or who need a starting 3D file for a design project without paying for cloud photo-to-3D services or waiting in their render queues.
Two representations come out of the same depth estimate: a textured relief mesh under studio-style lighting, and a vertex-colored point cloud that lays the scene's depth layers bare.
How it works
Depth Anything V2 Small, a state-of-the-art monocular depth network (Apache-2.0 licensed), runs in your browser through Transformers.js — on WebGPU where available, WebAssembly everywhere else. It maps every pixel to a relative scene distance, which the tool then turns into geometry: a subdivided plane displaced along the depth field and skinned with your original photo, or a point cloud sampled from the same field. Exports use the standard three.js exporters: GLB with the texture embedded, OBJ geometry, and USDZ that opens directly in AR Quick Look on iPhone and iPad.
Honest 2.5D — what it is and isn't
A single photograph contains no information about surfaces the camera never saw, so the tool reconstructs front-facing geometry only — in the spirit of the classic Facebook 3D photos rather than a full generative image-to-3D model like TripoSR or Meshy, which run on data-center GPUs and have no browser-capable quantized weights today. The back of an object stays flat. What you get instead is speed and privacy: depth in a couple of seconds, entirely on your own hardware, with standard 3D files as the output.
Getting better reconstructions
Photos with clear depth separation work best: a subject well in front of its background, layered foreground and scenery, a building seen at a slight angle. Depth strength controls how far the geometry protrudes toward the camera; smoothing softens the depth field before displacement, which helps on noisy scans; mesh detail trades vertex count for fidelity, while point size adapts the cloud. The grayscale depth map can be downloaded separately for use in other pipelines.
Limits & requirements
The model downloads once (~50 MB on WebGPU, ~27 MB on WebAssembly) and is cached by the browser; each photo afterwards processes in a few seconds. Chrome, Edge, and other Chromium browsers get the WebGPU path; Safari and Firefox run on WASM with identical output. Very flat subjects — document scans, perfectly frontal walls — have little depth to reveal. Mesh exports carry your photo as an embedded texture; OBJ is geometry only.
Privacy
Photos are decoded, depth-estimated, and rebuilt into 3D entirely inside your browser's memory. Nothing is uploaded, queued, or stored on a server, and there is no watermark or usage limit. Once the model is cached, the tool keeps working offline.
