3D tools in the browser

Converters, viewers and VRM tools for 3D files. Nothing to install, no account; uploads are deleted after 3 days.

Convert

One 3D format into another, with the skeleton, skin weights, shape keys and textures carried where the target format has room for them.

FBX to GLB

FBX in, one .glb with the images packed inside out. The page says what GLB cannot carry before you upload.

Open tool

GLB to FBX

GLB in, a binary .fbx that Unity, Unreal, Maya and Blender open out. The page says what FBX cannot carry before you upload.

Open tool

OBJ to GLB

OBJ in, one .glb with the images packed inside out. The page says what GLB cannot carry before you upload.

Open tool

GLB to OBJ

GLB in, an .obj with its .mtl and images, zipped together out. The page says what OBJ cannot carry before you upload.

Open tool

FBX to OBJ

FBX in, an .obj with its .mtl and images, zipped together out. The page says what OBJ cannot carry before you upload.

Open tool

Blender to FBX

Blender in, a binary .fbx that Unity, Unreal, Maya and Blender open out. The page says what FBX cannot carry before you upload.

Open tool

PMX to FBX

An MMD model, alone or with its texture folder zipped, as one binary FBX: bone names kept, morphs as shape keys, textures embedded.

Open tool

XPS to FBX

An XNALara / XPS model (.xps, .mesh, .mesh.ascii) as one binary FBX with its skeleton, weights and textures.

Open tool

View

Open a model in the browser and look at it before doing anything else. Nothing is uploaded: the viewers run on your own device.

GLB / glTF viewer

Open a .glb or .gltf, Draco and meshopt included, play the animations it carries, or drop a folder for a .gltf with its textures.

Open tool

FBX viewer

Open an .fbx with its embedded textures or a texture folder dropped alongside, and the animation clip it carries.

Open tool

OBJ viewer

Open an .obj with its .mtl and textures. Geometry only: the format has no skeleton and no animation.

Open tool

STL viewer

Open an .stl, ASCII or binary, and read its triangle count and size.

Open tool

PLY viewer

Open a .ply mesh or a point cloud with the colour each vertex carries; a scan with no faces is drawn as dots.

Open tool

DAE viewer

Open a Collada .dae with its textures from a folder or a zip, at its declared scale, and play its first clip.

Open tool

USDZ viewer

Open a text-encoded .usdz. A binary one is refused with a note and a link to the converter.

Open tool

PMX viewer

Open an MMD model (.pmx or .pmd) with its textures from a folder or a zip, with its morph sliders.

Open tool

3MF viewer

Open a .3mf print package: its objects, colours and the unit the file declares.

Open tool

3DS viewer

Open a legacy .3ds with its textures; the eight-character names inside are matched for you.

Open tool

3DM viewer

Open a Rhino .3dm: meshes, curves, points and layers, where Rhino saved a render mesh.

Open tool

VOX viewer

Open a MagicaVoxel .vox and read its voxel count, grid size and palette.

Open tool

G-code viewer

Step through a 3D print toolpath layer by layer: layer count, extruded length and print size.

Open tool

VRM viewer

Open a .vrm or .glb avatar: inspect its metadata and licence, test its expressions, play a clip, take a screenshot.

Open tool

VRM

Avatars for VTubing apps: make a VRM out of a rigged model, take one apart again, switch its version, pose it, trim it, animate it.

FBX to VRM

A rigged FBX, GLB, glTF, Blender file or archive becomes a VRM: bones mapped to the humanoid, materials and textures carried over.

Open tool

By source: Mixamo · MMD · Blender · Character Creator · Meshy

GLB / glTF to VRM

A rigged GLB, glTF or Sketchfab archive, a Ready Player Me avatar included, as a working VRM.

Open tool

Mixamo to VRM

A Mixamo-rigged character as a VRM: which bone names the converter expects and what it does with them.

Open tool

MMD to VRM

A .pmx or .pmd model with its textures as a VRM: Japanese bone names mapped, morphs kept as expressions.

Open tool

Blender to VRM

A .blend project opened on the server and written out as a VRM, hidden collections and all.

Open tool

Character Creator to VRM

A Reallusion Character Creator or iClone export as a VRM, with its facial shapes mapped.

Open tool

Meshy to VRM

A rigged Meshy export as a VRM, and which Meshy download to use when it is not rigged yet.

Open tool

Unity package to VRM

A .unitypackage avatar: the model inside is found, each material's texture read from the package, and it converts to VRM.

Open tool

VRM to FBX

A VRM as a binary FBX with its rig, blend shapes and textures, for Unity, Unreal or Blender.

Open tool

VRM 1.0 to 0.x

Switch a VRM between the two versions when an app refuses one of them. Geometry is untouched; the page lists what did not carry over.

Open tool

FBX to VRMA

A Mixamo FBX or a GLB animation as a .vrma clip that plays on any VRM, retargeted onto the humanoid and previewed first.

Open tool

VRM animations

Twelve motion-capture .vrma clips: idles, a walk, emotes, dances and flips. Preview any of them on your own VRM, download the full file.

Open tool

VRM poser

Pose a VRM in the browser with presets and per-bone sliders, then export a transparent PNG or the pose as a .vrma.

Open tool

VRM optimizer

Texture compression and shape-key-safe polygon reduction towards VRChat rank targets, with a built-in rank checker.

Open tool

Mesh

Make a model lighter, closed or textured, shrink a GLB, or make a solid out of an SVG or a line of text.

GLB compressor

Draco-compress a .glb, or a zip of up to 50, with textures, skins, morphs and animations kept; the page shows bytes before and after.

Open tool

Mesh decimator

Reduce any model to 5 000 to 100 000 triangles with UVs and skin weights kept; GLB, FBX, OBJ or STL out.

Open tool

LOD generator

The original plus 50 %, 25 % and 10 % of its triangles, four files in one zip, in the format you choose.

Open tool

Mesh repair

Merge doubles, drop loose geometry, fill holes and turn normals outward, with counts before and after; STL for the slicer.

Open tool

UV unwrap

Automatic texture coordinates for a mesh that has none: Smart UV Project at 66° with a 2 % margin, into a map named UVMap.

Open tool

SVG to 3D

An SVG's outlines filled and extruded to a depth, fitted to a width in millimetres; GLB, STL or OBJ out.

Open tool

3D text

Up to 64 characters in a bundled or uploaded font, with height, depth and bevel in millimetres, as GLB, STL or OBJ.

Open tool

Extract

Get the files out of a package without the program that made it.

Unitypackage extractor

Open a .unitypackage without Unity: every asset listed by its project path, saved one by one or as a .zip.

Open tool

Common questions

Is any of this paid?

No. Every tool on Shapeweld is free, and there is no account to make.

What happens to my files?

The viewers never upload anything. The converters keep an upload and its result for 3 days, then delete both.

How large can a file be?

Converters take files up to 100 MB (50 MB for the STL, PLY, DAE and USDZ pairs). The viewers are limited by your browser's memory.
