Turn any 2D image, photo, or sketch into a real, export-ready 3D model. Upload a JPG, PNG, or WEBP and export GLB, glTF, OBJ, or STL for Blender, Unity, Unreal, 3D printing, or web.
A 2D to 3D converter turns a flat image — a photo, sketch, or drawing — into a real 3D model you can preview, edit, and export. It reconstructs depth, mesh structure, and textures from the 2D input so the result is genuine 3D geometry, not a 3D-looking image.
Upload a JPG, PNG, or WEBP photo, sketch, or drawing as the source.
AI reconstructs depth, geometry, and PBR textures from the flat image.
Inspect the model from any angle in a real 3D viewer, not as a flat image.
Download GLB, glTF, OBJ, or STL, or open in Studio for cleanup.
These tools sound similar but do completely different things. This page generates new 3D models from 2D images. Extrusion tools give you a relief; file converters give you the same model in a different container. Pick by what you need downstream.
Takes a flat image and creates a new 3D model. The output did not exist before — geometry is generated from a photo, sketch, or drawing.
Takes an existing 3D model and changes its format. No new geometry is created — only the container changes (OBJ to GLB, glTF to STL).
Extrusion tools read pixel brightness and turn it into height. ImageToStl's own FAQ describes it plainly: "3D geometry is created based on the luminosity of each pixel in the source image." A black pixel becomes 0mm, a white one becomes 10mm. Great for lithophanes, nameplates, and relief-style prints — but the output is a heightfield: geometry with no back side.
Upload, generate, and export. The 2D to 3D conversion flow takes under a minute for most references and produces a model you can open in Blender, Unity, Unreal, or a web viewer.
Start from a JPG, PNG, or WEBP product photo, character concept, architecture shot, or sketch. Clear single-subject references produce the cleanest 3D geometry.

Trify3D reconstructs depth, mesh structure, and PBR texture detail so the result is a real 3D model, not a flat image with depth shading.

Trify3D produces genuine 3D meshes with reconstructed geometry and PBR textures. The result is editable in Blender, ready for Unity and Unreal, and works in web viewers — not a flat image with depth shading.

The single biggest quality lever is the input image. Follow these four rules and the converter produces noticeably better geometry.
One main object per image produces the cleanest 3D mesh. Multiple subjects confuse depth reconstruction.
White, transparent, or solid backgrounds help the model separate the subject from noise.
Soft, diffuse lighting reveals true shape and color. Harsh shadows create unwanted geometry and texture artifacts.
Sharp silhouette edges give the converter clean contours. Blurred or occluded edges reduce mesh accuracy.
Groups of objects, cluttered backgrounds, and heavy overlap between subjects all degrade the result. The model has to guess what it cannot see, and guesses show up as lumps and holes in the mesh.
Open, broken, or ambiguous strokes translate into open edges in the geometry. Close your outlines and even out line weight before uploading — it takes a minute and visibly cleans up the mesh.
Each export format targets a different downstream workflow. GLB for web and AR, glTF for DCC interchange, OBJ for modeling, STL for 3D printing.
| Format | Use case | Software |
|---|---|---|
| .glb Three.js, Babylon.js, Web, AR | GLB for web and AR Single-file binary glTF with embedded textures. Ideal for Three.js, Babylon.js, web viewers, and AR try-on flows. | Three.js, Babylon.js, Web, AR |
| .gltf Blender, Maya, inspectors | glTF for DCC interchange The human-readable sibling of GLB, split across .gltf + .bin + textures. Useful for inspecting or hand-editing the scene. | Blender, Maya, inspectors |
| .obj Blender, Maya, ZBrush | OBJ for modeling tools Wavefront OBJ geometry with separate MTL material definition. Compatible with most legacy and modern modeling pipelines. | Blender, Maya, ZBrush |
| .stl Cura, PrusaSlicer, CNC | STL for 3D printing Stereolithography mesh format used by slicers and CNC tools. Watertight meshes ready for additive manufacturing. | Cura, PrusaSlicer, CNC |
Need a different workflow? Every export can be converted downstream — run results through the GLB to STL converter for printing, try the image-to-STL tool if a flat relief is all you need, or open results in the STL viewer to check geometry before you download.
Different 2D inputs produce different 3D results. Photos give realism, sketches give stylized meshes, product shots feed e-commerce, and concept art feeds game pipelines.
Single-subject product photos, portraits, and object shots convert into textured 3D models with accurate silhouettes and color.
E-commerce, AR try-on, visualization
Line art and concept sketches convert well when lines are closed, symmetrical, and evenly weighted.
Concept prototyping, stylized props
E-commerce product photos with plain backgrounds turn into GLB assets for PDPs and configurators.
PDP previews, AR, configurators
Character concepts and prop references become GLB assets ready for Unity and Unreal pipelines.
Game props, character art, animation
Being upfront about the edges of the technology. For each limitation below there is a path forward — multi-view input or Studio cleanup.
A single image may not capture occluded geometry. For complex subjects, multi-view references improve accuracy.
Hair-thin structures, glass, and transparent plastics may reconstruct with artifacts. Plan cleanup in Studio.
The converter produces draft-ready meshes. For engineering-grade or animation-ready topology, retopologize downstream.
Common questions about converting 2D images, photos, and sketches into 3D models — including what it is, what inputs work, and how it differs from a 3D file converter.
A tool that turns a flat image — a photo, sketch, or drawing — into a real 3D model you can rotate, edit, and export. It is not the same as a 3D file converter, which only switches existing 3D files between formats like OBJ, GLB, and STL without creating anything new.
A real mesh. You can open it in Blender, Unity, or Unreal, orbit around it, and see actual geometry on the back side — not a depth-of-field effect baked into a photo.
JPG, PNG, and WEBP. Photos, product shots, character concepts, and line drawings all work. WEBP included — no need to convert your file first.
Yes. Closed lines and even stroke weight convert cleanly; open or ambiguous strokes leave ragged edges in the mesh. Fix the drawing before uploading and the model comes out noticeably better.
Yes — single-object shots on a plain background are the ideal input. The resulting GLB drops straight into e-commerce viewers, AR try-on, and configurators.
Extrusion tools map pixel brightness to depth, so a logo becomes a relief — flat on the back. AI generators treat the image as a reference for a whole object and build a full mesh with a back, sides, and PBR textures. If you need a printable relief, use an extrusion tool; if you need an object, use this.
Usually under a minute for a clear single-subject image. Complex inputs and heavier quality settings take longer.
You can try it free with welcome credits, and signing up doesn't require a credit card. A standard image-to-3D generation costs about 10 credits, so the free credits cover a handful of real conversions — enough to judge the quality before paying anything.
Yes, alongside GLB, glTF, and OBJ. Before slicing, check the mesh is watertight — a closed volume with a clear inside and outside — since that's what slicers need for a clean print. Maxon's 3D printing guide calls it the single most important requirement.
GLB and glTF load natively in Blender and are supported across engines like Unity and Unreal, per the glTF 2.0 documentation. Prefer OBJ for ZBrush-style sculpting workflows.
No. Those results are about video processing hardware that converts 2D video into stereoscopic 3D in real time. This tool does something different: it builds a 3D model file from a single still image.
That depends on your plan and on the rights you hold to the source image. Use images you own or are licensed to use, and check the terms for the specifics.
