A VRM file is a 3D avatar for VTubing, social VR and games — a binary glTF with extra data for the skeleton, facial expressions, hair and cloth physics and the author's license. This viewer reads all of it in your browser.
What you can check
- The avatar in 3D, with orbit, zoom and an idle motion that swings hair and clothes through the avatar's own spring bones.
- Expressions — every preset and custom expression (happy, angry, blink, the mouth shapes
aa,ih,ou,ee,oh…) on its own slider. - Author and license: name, authors, version, contact, references and the permissions the author set — who may use the avatar, commercial use, violent or sexual content, credit, redistribution and modification.
- Contents: triangles, meshes, materials (and how many use MToon), textures, humanoid bones and spring bone joints.
- The thumbnail stored in the file.
VRM 0.x and VRM 1.0
Both versions open. VRM 0.x avatars face the other way and store their license as named fields such as allowed user and commercial usage; VRM 1.0 uses the newer permission list. The viewer turns 0.x avatars around and shows each version's fields in plain words.
VRM to GLB
Download as GLB writes the same file without the VRM extensions. Geometry, skin, morph targets, materials and textures stay byte for byte; only the VRM-specific data — humanoid mapping, spring bones, expressions, MToon settings — is removed, so tools that expect a plain glTF accept it.
Limits
- The preview is a viewer, not an editor: changes to expressions and pose are not saved into the file.
- VRM animation files (
.vrma) are not played. - Conversion between VRM 0.x and 1.0 is not offered.
