Work with
- One subject, centered, filling most of the frame
- A clean outline against a plain background
- Even lighting with no hard shadow across the subject
- A three-quarter view that shows the sides
- At least 1024 px on the long edge
Image to 3D Generator
Img3D turns one image into a 3D asset. Upload a product shot, a render, or a clean photo, and the workspace returns a GLB model you can orbit and measure in the same browser tab. The local tools never upload your files; the generation step is the one part that talks to a server.
Free daily allowance. No account, no card, no sign-in.
How an image becomes a 3D model here
- Pick the source image. Upload a PNG, JPG, WebP, or AVIF file in the generator workspace, or paste a public image URL when the file is already online.
- The source image is reviewed. An automated review runs before any GPU work starts, so an image that fails the check is not generated.
- The run is queued. Img3D runs one enabled model, image to GLB, on a shared GPU queue. A run takes a few minutes rather than seconds.
- The result is a GLB. Open it in the 3D Viewers workspace to check orientation, bounding box, and estimated vertex count.
- Plan the handoff. Use the 3D Converters workspace to map the route to OBJ, FBX, STL, PLY, glTF, or USDZ, and the utilities to check textures and scale.
Source images that survive the trip to 3D
A single-image pipeline reads the silhouette more than anything else, so the input decides most of the output quality.
Avoid
- Cluttered or busy backgrounds
- Motion blur and heavy depth of field
- Transparent glass, thin hair, and fabric folds
- Tight crops that cut the object off
- Flat front-on shots of a shape with no visible depth
More examples sit in the source image gallery on the main workspace page.
What you get back
- A GLB model. The file carries the generated geometry and the material written from your source image.
- Browser-side checks. The viewer reports format, file size, bounding box, and an estimated vertex count, so you can judge the asset before importing it anywhere.
- A route to the format you need. The converter workspace maps the practical path from the GLB to OBJ, FBX, STL, PLY, glTF, or USDZ and names the validation step for that path.
- Image preparation. Resize or convert the source and reference images in the Image Tools workspace without another upload.
The free daily allowance
Generation runs on a shared GPU, so Img3D caps it: every caller address gets a daily allowance, and addresses behind the same network share that allowance. The viewer, converter, texture, scale, and image workspaces are browser-local and are not capped at all.
The allowance is charged before the GPU step. If a run fails after that step, the first such failure in a window is returned to your allowance automatically, so one broken run does not cost you the day.
Image to 3D, img to 3D, photo to 3D
People search these as separate phrases, but they ask for the same thing: a 2D image in, a polygonal asset out. Img3D covers that path for objects and props. If your input is a photo of a person or a portrait and you want a hosted editor rather than a browser-local workspace, the Photo3D sibling site runs that pipeline.
Where this pipeline stops
Honest limits: a single image cannot reveal geometry that is hidden behind the subject, so the back of the model is inferred rather than measured. The output is a mesh with a material, not a rigged, retopologized, or parametric model. For watertight print geometry, treat the result as a starting shape and finish it in a modeling or sculpting tool.
Photo and portrait to 3D
Photo3D is our sibling site for photo to 3D work. It runs a hosted image to 3D model flow with a free entry point, which suits portrait, pet, and product photos where you want a finished viewer page rather than a local GLB check.
Questions about image to 3D
Is image to 3D generation on Img3D free?
Yes. Generation is free and capped by a daily GPU allowance shared across the addresses behind your network. No account is needed anywhere on the site.
What file does the image to 3D generator return?
A GLB file. You can open it in the local viewer, then plan the route to OBJ, FBX, STL, PLY, glTF, or USDZ in the converter workspace.
How long does one image to 3D run take?
Generation runs on a shared GPU queue, so a run takes a few minutes rather than seconds, and the queue can be busy at peak times.
What happens if the run fails?
The allowance is charged before the GPU step. When a run fails after that step, the first such failure in a window is returned to your allowance automatically.
