3D Simplify: USDZ Optimizer

Scanned a room, a product or a statue and ended up with a file too heavy to send or open? 3D Simplify shrinks LiDAR, photogrammetry and Object Capture scans, and any downloaded model, into a light USDZ that opens instantly in AR Quick Look, Messages and web stores. It cuts the polygon count on your device, and Re-bake Textures (Pro) re-wraps the original texture onto the lighter mesh so surfaces stay sharp instead of smeared. Nothing is uploaded, no account to create.

WHO IT IS FOR
• 3D scanning users whose LiDAR, photogrammetry or Object Capture results are too heavy to share or open in AR
• AR, RealityKit and visionOS developers who need assets that load quickly in AR Quick Look
• Game developers building LODs and trimming heavy props for real-time engines
• Online stores and web teams shipping 3D product models that have to download fast
• Architecture and product design teams turning heavy models into something an iPhone can show

HOW IT WORKS
1. Import a model from the Files app - USDZ, USD, USDA or USDC.
2. Let Auto pick the reduction, or set it yourself with the Pro ratio slider, and compare Original and Simplified side by side.
3. Rotate, preview, name the file, and export a USDZ.

FREE
• Automatic smart reduction that picks the target polygon count for you
• One-tap Original / Simplified switch at the same camera angle, with before-and-after stats side by side
• Live face count, reduction percentage and estimated file size
• 3D rotation controls and preview in the export sheet
• Custom export file name
• Batch Reduce for a folder of up to 3 models at a fixed 50% reduction (OBJ is accepted here too)
• Skip Small Models: files under a size you set are copied through untouched
• Interface in English, 繁體中文, 简体中文, 日本語 and 한국어

3D SIMPLIFY PRO
• Manual ratio slider in 5% steps, from Minimal to Aggressive
• Texture Size: export textures at Original, 1/2 or 1/4 to cut file size further
• Re-bake Textures: re-atlases the mesh so a heavy reduction does not leave smeared or stretched seams - built for photogrammetry, Object Capture and LiDAR scans
• Hausdorff quality reading and output validation after a re-bake, showing how far the simplified surface has moved from the original
• Saved Models Library: keep results and reload them later
• Unlimited files per batch run
• New Pro tools as they ship

FORMATS
• Import: USDZ, USD, USDA, USDC (OBJ in Batch Reduce)
• Export: USDZ

PRIVACY AND PERFORMANCE
Everything runs on your device and the texture atlas step is Metal-accelerated. No account, no upload, no cloud - it works in airplane mode.

PLEASE NOTE
3D Simplify is not a 3D scanner, a modelling app or a format converter. It takes a model you already have and makes it lighter, and export is always USDZ. It does not remesh, retopologise or repair broken geometry. Reducing a mesh always removes detail, so the side-by-side view is there for you to decide how much is acceptable.

PLATFORMS
iPhone and iPad (iOS/iPadOS 17 or later) and a native Mac app (macOS 14 or later).
