Compress your VRM — without breaking it
Oversized textures are why your avatar is 60 MB. Resize them right in your browser — rig, expressions and materials stay untouched, and you can inspect the result in 3D before downloading. Analysis, the rank checker and the preview are free; downloading the optimized model costs 1 credit (your first is free on signup). Nothing is ever uploaded.
Frequently asked questions
How does it reduce the file size?
Almost all of a VRM's weight is textures — avatars often ship with 4K maps where 1K is indistinguishable in VTubing apps. The optimizer resizes textures above your chosen limit (2048/1024/512/256px; only limits that actually shrink your file are offered) and rebuilds the file. Optionally it also reduces polygon count toward VRChat rank targets. Bones, expressions and VRM metadata are untouched.
Can it reduce the polygon count?
Yes — pick a target next to the texture settings: Fit Good (70k), Fit Excellent (32k) or −50%. The reduction is morph-safe: it only collapses triangles between existing vertices, so blendshapes, lip-sync and skin weights survive. Preview the reduced model in 3D before paying anything.
How much does it cost?
Analysis, the VRChat rank checker and previewing the optimization results are free and unlimited. Downloading the optimized model costs 1 credit — your first credit is free on signup, then packs: 3 for $7.99 or 8 for $14.99, shared with the FBX converter. You see the exact size and triangle numbers before you pay.
What is the VRChat rank estimate?
We compute your avatar's triangles, material slots, skinned meshes, bones and estimated texture VRAM, and compare them against VRChat's official PC performance-rank limits. It's an estimate — Unity import settings can shift the numbers — but it reliably shows what is dragging your rating down.
Will it break my avatar?
No. Texture optimization only replaces image payloads (PNG stays PNG, so transparency is safe), and polygon reduction preserves the rig and every blendshape. Preview the result in 3D before downloading.
Is my file uploaded anywhere?
No. Everything runs in your browser — parsing, resizing, polygon reduction and rebuilding. Your avatar never leaves your device.
