Inspect OBJ Models with Materials and Textures
Upload an OBJ file along with its MTL material file and texture images. Orbit, zoom, toggle wireframe, cycle through lighting environments, and export a PNG screenshot.

OBJ with MTL and Textures
Drop your OBJ file together with its MTL material file and any texture images in one go. The viewer loads all materials and maps textures automatically.
Open Viewer
Orbit, Zoom, and Inspect
Left-click and drag to orbit around the model. Scroll to zoom. Right-click and drag to pan. Snap to Front, Top, or Right with camera preset buttons.
Open Viewer
Wireframe, Lighting, and Screenshot
Toggle wireframe to inspect the triangle mesh topology. Cycle through ten environment lighting presets to preview materials. Capture a PNG screenshot at any camera angle.

Upload your OBJ file
Drag your OBJ file onto the drop zone — optionally add the matching MTL file and texture images at the same time. The viewer loads all files together and renders the model.
Navigate and inspect
Orbit the model with left-click drag, zoom with scroll, and pan with right-click drag. Use camera preset buttons to snap to Front, Top, or Right views.
Switch lighting and capture
Cycle through ten environment presets to see how materials respond to different lighting conditions. Toggle wireframe to inspect geometry, then take a PNG screenshot.
Deep Dive
What the OBJ Viewer Supports
Built for the full OBJ workflow — geometry, MTL materials, and texture images — not just raw geometry rendering.
Why Use the OBJ Viewer
MTL and Texture Support
Load an OBJ with its MTL file and texture images in one go. Materials and textures apply automatically, no configuration needed.
Full Geometry Inspection
Orbit, zoom, and pan to inspect every surface. Toggle wireframe to check mesh topology without printing or exporting.
Lighting Environments
Cycle through ten environment presets to verify how diffuse and specular materials look under studio, outdoor, and architectural lighting.
Screenshot Export
Save any camera angle as a PNG for documentation, design reviews, or sharing with collaborators.
Who Uses It
Who Uses a Browser-Based OBJ Viewer
Quickly previewing an OBJ model without opening a 3D application saves time for designers, engineers, educators, and developers.

Frequently Asked Questions
What is an OBJ file?
OBJ (Wavefront Object) is a human-readable ASCII 3D geometry format developed by Wavefront Technologies in 1989. It stores vertex positions, texture coordinates, vertex normals, and polygon faces. It is one of the most universally supported 3D formats and is exported by Blender, Maya, 3ds Max, SketchUp, and virtually every other 3D application.
Do I need to upload the MTL file too?
No — the OBJ file loads on its own with a default material. If you want materials and colors, select both the OBJ and the matching MTL file at the same time. If the MTL references texture images, include those files in the same selection as well.
Which texture formats are supported?
The viewer accepts PNG, JPG, JPEG, BMP, and TGA image files. Select the texture images alongside the OBJ and MTL when uploading. The viewer matches each texture filename referenced in the MTL to the uploaded image files automatically.
How do I navigate the 3D model?
Left-click and drag to orbit (rotate) around the model. Scroll the mouse wheel to zoom in and out. Right-click and drag to pan the camera. On touch devices, use one finger to orbit, pinch to zoom, and two fingers to pan. The camera preset buttons (P, F, T, R) snap to Perspective, Front, Top, and Right views.
What does wireframe mode do?
Wireframe mode renders only the triangle edges of the mesh, hiding solid surfaces. This makes it easy to inspect mesh density, check for n-gon faces, detect inverted normals, and understand the underlying geometry structure.
Why does my model appear very small or very large?
OBJ files carry no inherent unit information — a model exported in millimetres will appear 1000 times smaller than one exported in metres. The viewer auto-scales every model to fit a consistent 2-unit bounding box, so it always renders at a reasonable size regardless of the original export units.
Is there a file size limit?
There is no server-imposed limit because all processing happens in your browser. Very large OBJ files (over 50 MB) may load slowly depending on your device memory. Most models under 20 MB load and render smoothly on modern hardware.
Which browsers are supported?
The viewer works on Chrome, Firefox, Edge, and Safari on desktop and mobile. WebGL 2.0 support is required. All modern browser versions from the past two years support this.
