Zipoly.3D Model Compression & Optimization Tool
Zipoly is a 3D model compression and optimization tool for 3D artists, web developers and industrial visualization teams,
featuring dual-engine Draco/Meshopt compression, KTX2 texture optimization, conversion between 7 formats, and batch processing.
It runs fully offline — data never leaves your machine — with a privately deployable Server API team edition.

Core Capabilities
From Compression to Delivery, All in One
Draco geometry compression
Up to 90% size reduction, native support in Three.js / Babylon.js, fine-grained parameter tuning
Meshopt engine
Higher compression, faster decode, auto-fallback to Draco on failure
KTX2 GPU textures
Cut texture size by 90%, GPU-native decoding without CPU cost, zero rendering overhead
Node data tagging
Click model nodes to bind business data, JSON import/export, essential for industrial visualization
Model diagnostics
Auto-scan on import: duplicate vertices, oversized textures and more at a glance
Batch processing
Process a whole folder at once, pause / resume / cancel anytime, live progress
7 formats conversion
FBX / OBJ / STL / DAE / PLY to GLB in one click, textures auto-embedded
Pro viewer
Section view, animation preview, sunrise/sunset simulation, free screenshots & recording
Fully offline
No internet, no registration, data stays local — safe for confidential projects
Dual-Engine Comparison
Draco or Meshopt?
Not sure which one? Go with Meshopt — better compression, auto-fallback to Draco on failure.
- Up to 90% compression, mature and stable
- Native support in Three.js / Babylon.js / model-viewer
- JPEG / WebP / KTX2 texture output
- Levels 1–10 + fine-grained quantization
- Geometry-only, no vertex cache optimization
- Better compression plus vertex cache optimization
- Integrated BasisU textures (ETC1S / UASTC)
- WebGPU-friendly, faster load & decode
- Auto-switch to Draco, seamless fallback
- Not yet supported in Babylon.js / model-viewer

FAQ
Frequently Asked Questions
Compression results, pricing and data safety — the four questions we hear most.
View all FAQsMy GLB model is too large and loads slowly — how small can Zipoly make it?
The dual Draco/Meshopt engines reduce size by up to 90% (official example: 45.8 MB → 3.2 MB in under a second). Drop a GLB into Zipoly and compress with one click — the result loads directly in Three.js / Babylon.js / model-viewer.
Is Zipoly free? What does it cost?
The free tier is available forever with 20MB per-file limits (5MB textures), one file at a time. Paid plans: ¥15/30-day Trial, ¥79/year Personal, ¥199 lifetime (launch offer), and Team from ¥299/year per seat with private deployment.
Does Zipoly upload my models to a server?
No. The desktop app runs fully offline with no sign-up — data never leaves your machine. For teams, the privately deployed Server edition keeps models inside your intranet.
Does it convert FBX, OBJ or STL to GLB?
Yes — 7 formats (GLB, glTF, FBX, OBJ, STL, DAE, PLY) convert both ways. External textures are auto-embedded into a single-file GLB, which you can then compress for further size reduction.
