3D Viewer Online review
A low-cost browser viewer with useful inspection, markup, sharing, and embedding tools.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
3D Viewer Online is a browser-based platform for viewing, inspecting, measuring, annotating, and sharing 3D and 2D models. It supports formats including STEP, IGS, OBJ with MTL and texture, STL with colors, PLY, DWG, DXF, glTF, and 3MF. Its audience includes engineering teams, manufacturers, ecommerce users, and other professionals who need model access without installing desktop CAD software. The viewer also includes lighting, shading, reflections, viewer customization, sectioning, exploded views, and multiple model uploads.
Pricing is structured around a free plan and paid tiers. The Regular plan includes model viewing, a 10-model account limit, a 50 MB maximum file dimension, and basic support. The Premium plan is listed at $15 per month when billed annually and adds 25 GB of storage, private models, comments, markups, annotations, and iFrame integration. Business costs $35 per month when billed annually and adds 1 TB of storage, private models, advanced collaboration, and custom viewer settings. Enterprise uses custom pricing. A 14-day free trial is also available.
The product fits teams that want browser-based access with practical geometry review and collaboration tools. Its sharing options support shared model links, while integrations include iFrame, WordPress, Magento, and API access. Those options make it suitable for websites, applications, and ecommerce workflows as well as internal review. The trade-off is a web-only platform with plan-based storage and model limits, plus no verified presentation mode. Teams needing desktop access or presentation-focused model delivery should consider an alternative; teams prioritizing affordable viewing, inspection, markups, and embedding should pick 3D Viewer Online.
