How to use 3DViewerConvert

Quick guides to formats, embedding and storage - written for humans, kept short on purpose.

Last updated: January 5, 2026

Supported 3D formats

The viewer opens 17+ file formats from CAD, BIM, 3D-printing and web pipelines. Everything is parsed locally in your browser - nothing is uploaded unless you share it. Formats with a dedicated page link to their own viewer (and SEO landing) below.

Alias tip: STP loads as STEP, and IGS loads as IGES.

Embedding with an iFrame

Turn any shared model into an interactive embed for your product page, portfolio or documentation. The viewer renders in a standard HTML iframe - no JavaScript SDK required.

1
Publish a share link. Load the model and click Share in the toolbar; the viewer creates a permanent public link like /v/example-id.
2
Copy the embed code. The Share dialog offers a copy-paste iFrame snippet on the Pro plan. The ?embed=true query renders a brand-free, white-label viewer.
3
Paste it into your page. Any HTML page, CMS, Notion doc or storefront can host the embed. Visitors rotate, zoom and (if you allow it) export without leaving your site.

<iframe
  src="https://3dviewerconvert.com/v/demo-glb?embed=true"
  title="3D model viewer by 3DViewerConvert"
  width="100%" height="480"
  allow="autoplay; fullscreen; xr-spatial-tracking"
  allowfullscreen
  style="border:0; border-radius:8px; background:#09090b;"
></iframe>

Storage quotas: Free vs Pro

Your account has a personal workspace: a model list plus cloud storage for everything you publish. Quotas are enforced server-side, and the Dashboard shows a live progress bar.

Feature	Free	Pro
Models in workspace	5	Unlimited
Cloud storage	50 MB	5 GB
Max upload size	50 MB	50 MB
iFrame embedding	-	Included
Export control on shares	-	Included
White-label (no watermark)	-	Included

Hitting a limit? Your existing models stay safe and accessible - you simply cannot add new ones until you remove older models from the Dashboard (each deletion frees its storage immediately) or upgrade to Pro.

Need more room? Pro starts with 5 GB and unlimited models.
