Free 3D tool

Free online 3D tools

View, convert, optimize and prepare 3D models right in the browser. Built for game developers and 3D artists — nothing is uploaded, no account needed.

View 3D files

Open 24 model formats in the browser and inspect geometry, materials and animation.

3D Viewer

Open GLB, FBX, OBJ, STL and 20 more formats; LODs, variants, stats.

Wireframe Viewer

See the polygon mesh of any 3D model, with wireframe over solid shading.

UV Checker

Check UV unwrapping with a checker texture and see the UV layout.

Flipped Normals Checker

Find flipped faces: back sides are painted red.

PBR Channel Viewer

Look at base color, normals, roughness and metalness one channel at a time.

Lighting Preview

Preview a model under studio, sun, overcast, sunset and night light.

3D Model Measure Tool

Measure distances on a 3D model and compare it with a 1.8 m person.

Compare 3D Models

Compare two 3D models or two LODs side by side with a slider.

LOD Viewer

See LOD levels switch by distance, like in a game engine.

Texture Inspector

List the textures in a model with size, slot and video memory.

Polygon Counter

Count triangles and vertices of a 3D model, mesh by mesh.

Convert

Turn any model into GLB, glTF, OBJ, STL, PLY or USDZ — one click, no install.

3D Model Converter

Convert FBX, OBJ, STL, GLB, DAE, 3MF, USDZ and more to GLB, glTF, OBJ, STL, PLY or USDZ.

FBX → GLB OBJ → GLB STL → OBJ GLB → OBJ GLB → STL OBJ → STL DAE → GLB USDZ → GLB 3MF → STL SVG → STL VOX → GLB glTF → GLB All conversions →

Optimize

Make models lighter and ready for engines: compression, polygon reduction, LODs, scale and validation.

GLB / glTF Compressor

Shrink GLB files: Meshopt geometry, WebP or KTX2 (Basis) textures.

Polygon Reducer

Reduce triangle count of any model while keeping its shape.

LOD Generator

Generate LOD0–LOD4 from one model, named for Unity and Unreal.

Scale & Axis Fixer

Fix units, Z-up/Y-up and the pivot of a model before import.

glTF Validator

Check GLB and glTF files with the official Khronos validator.

For games

Sprite sheets from 3D models and 360° turntable videos for stores and trailers.

3D to Sprite Sheet

Render a model from 4, 8 or 16 directions into a sprite sheet for 2D games.

360° Turntable Video

Record a spinning video of a 3D model for stores, portfolios and trailers.

3D Model to GIF

Turn a 3D model into a 360° rotating GIF.

3D Model to PNG

Render a 3D model to a 4K PNG with a transparent background.

Textures

Normal maps, seamless tiling textures and KTX2 conversion.

Normal Map Generator

Make a normal map from any image — OpenGL or DirectX.

Seamless Texture Maker

Make any texture tile without visible seams.

Image to KTX2 Converter

Convert PNG and JPG textures to KTX2 (Basis Universal ETC1S or UASTC) with mipmaps.

3D printing

Check STL files for holes and broken geometry and repair them before slicing.

STL Checker & Repair

Find holes and broken edges in STL files and repair them before printing.

Generate

Terrain from heightmaps, procedural trees and ready-made game assets.

Heightmap to 3D Terrain

Turn a heightmap image into a terrain mesh — GLB, OBJ or STL.

Tree Generator

Procedural game-ready trees with LODs, wind and collision — in the browser.

3D Asset Catalog

180+ trees, plants and rocks with LOD0–LOD3 for Unity, Unreal and Godot.

Need game-ready trees, plants and rocks?

FoliMesh generates vegetation and rocks with LOD0–LOD3, collision and a pivot at the base — GLB, FBX or OBJ for any engine.
