How to animate a 3D model in 3 steps

01
Drop a rigged character
Drag a GLB, glTF, FBX or DAE file with a humanoid skeleton onto the tool above, up to 200 MB. The panel names the rig it found (for example Mixamo rig detected) and how many of the 22 humanoid bones it matched. No rigged file at hand? Try the sample character loads a CC0 mannequin from Mesh2Motion.
02
Pick and preview animations
Search the library or filter by Idle, Walk & run, Combat, Jump & move, Gestures, Everyday or Dance. Click a clip and it is retargeted onto your skeleton and plays on the stage. Pause, scrub the timeline, switch speed between 0.5× and 2×, and toggle Bones to see the skeleton move.
03
Download the animated GLB
Press Add to GLB on every clip you want, then Download GLB. One file carries all of them as named animations. Download this pose saves a still GLB frozen at the frame on screen instead.

What the animation retargeter does

Retargeting means taking motion recorded on one skeleton and replaying it on another whose bones have different names, lengths and rest pose. That is the whole job of this tool: use it to add animation to a 3D model that is already rigged.

Reads common rig names

Mixamo (with or without the mixamorig: prefix), Meshy, Mesh2Motion and the Unreal mannequin, SMPL-H, VRoid, Character Creator and Unity-style humanoid names are matched automatically.

T-pose or A-pose

Each bone's direction and roll are measured from your own rest pose, so a T-posed clip lands correctly on an A-posed character. Z-up and backwards-facing rigs are turned upright first.

Scaled to your character

Hip movement is scaled by the ratio of hip heights, so a jump or crouch fits a child-sized figure and a giant alike, in centimeters or meters.

Several clips per file

Add an idle, a walk and an attack, and the GLB holds three named animations that Blender, Unity, Godot and three.js list separately.

Your file stays intact

A GLB keeps its own meshes, materials and textures byte for byte; only the new animations are added. FBX and DAE files are written out as GLB.

Runs in a background worker

Clips download one at a time (about 20 KB each) and bake in a Web Worker, so the page keeps playing while a clip is prepared. Nothing is uploaded.

Not supported: four-legged creatures, characters without a skeleton, and root-motion clips (each clip plays in place).

Got a static model? Rig it first

You can only animate a 3D model here if it already has bones. A model fresh out of an AI generator, a sculpt or a scan is a single static mesh: drop it here and the panel says No skeleton in this file. SupaVoxel's image to 3D studio makes static models too; it does not rig or animate them.

The usual free route is Mixamo: upload the FBX or OBJ, place the markers on the wrists, elbows, knees and groin, and download the rigged character. Our Mixamo guide walks through it. Bring that rigged file back here to retarget the CC0 library onto it and export GLB without converting from FBX first; or open any file in the 3D model viewer to check whether it has a skeleton.

A Mixamo alternative for adding animation to a 3D model

Mixamo is the better choice when you need auto-rigging or its much larger motion library, and it only asks for an Adobe ID. This tool is the lighter way to get 3D animation online when the character is already rigged: no account, no upload, nothing to install, and the result is a GLB rather than an FBX per clip. It also accepts rigs Mixamo never made, such as Meshy, VRoid or Unreal-style skeletons.

For a still pose, play a clip, pause on the frame you want and press Download this pose; it pairs well with the AI pose changer. An FBX character can go straight in, and FBX to GLB covers files with no rig at all. For the web, shrink the animated result with the GLB compressor.

Tips to animate a 3D model cleanly

Use a character standing in a T-pose or A-pose, facing forward, in its rest pose
Turn on Bones to check that the skeleton moves with the mesh
Pick looping clips (idles, walks, dances) for game characters, one-shots for cutscenes
Re-check hands and props: fingers are not animated, so fists stay open

Avoid

Expect a static mesh to move; it needs bones and skin weights first
Use it for quadrupeds, wings or tails; the library is human only
Expect feet to lock perfectly on characters with very short or long legs
Ship a file without testing it in your engine's importer

FAQ

Frequently asked questions

Is this 3D animation tool free?

Yes. There is no account, watermark or export limit. The 160 animations are Mesh2Motion's CC0 clips, which you can use in commercial games and videos without credit, and the retargeting runs on your own computer, so there is no server cost to pass on. You can export as many animated GLB files as you like.

How do I animate a 3D model that has no skeleton?

Rig it first. A skeleton (bones plus skin weights) is what any animation moves, and this tool doesn't create one. Mixamo's free auto-rigger does it in a few minutes: upload the model, place markers on the wrists, elbows, knees and groin, and download the rigged FBX. Then drop that file here and pick animations.

Which rigs can I add animation to?

Humanoid skeletons whose bone names follow Mixamo, Meshy, Mesh2Motion or the Unreal mannequin, SMPL-H, VRoid, Character Creator or Unity humanoid conventions. The panel shows which one it detected and how many of 22 bones matched. If hips, an arm or a leg is missing, it lists the missing bones instead.

Does it work with Mixamo characters?

Yes. Mixamo FBX downloads, and GLBs converted from them, are detected with or without the mixamorig prefix (numbered ones like mixamorig1 too). The animations come from the CC0 library rather than Mixamo's, and you can keep the Mixamo clips the file already has by turning on Keep the file's own animations before you export.

What does retarget animation mean?

Retargeting replays motion made for one skeleton on another. Bones are matched by role (left forearm to left forearm), then each target bone is rotated so it points and rolls the way the source bone does, starting from its own rest pose. Hip movement is scaled to the new character's leg length.

Can I export FBX instead of GLB?

Not from this tool; the output is always GLB, which Blender, Unity (with glTFast), Unreal, Godot, three.js and Babylon.js import with animations. If your pipeline needs FBX, import the GLB into Blender and export FBX from there.

Why do the fingers not move?

The retargeter drives 22 body bones: hips, spine, neck, head, clavicles, arms, hands, legs, feet and toes. Finger and face bones differ too much between rigs to map reliably, so they keep the pose they have in your file. Characters modeled with relaxed hands look most natural.

Is my model uploaded anywhere?

No. The model is read, retargeted and written by JavaScript in your browser tab. The only downloads are the library clips themselves, about 20 KB each, fetched when you pick one. Closing the tab removes everything.
