ChemViz3D review
A free web tool for creating, editing, and exporting chemical animations and diagrams.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
ChemViz3D is a free, browser-based chemistry teaching platform for students, educators, and researchers. Its core workflow combines interactive 3D reaction animations, molecule visualization, animation editing, and 2D chemical diagram and equation tools. Users can rotate scenes, pause animations, inspect atoms and bonds, create custom reaction animations, and convert 2D chemical animations into 3D. The Free plan includes 3D reaction animations, molecule visualization, animation editing, and 2D chemistry tools, making ChemViz3D a fit for individual learning and teaching focused on visual explanation.
Its strongest differentiator is the connection between chemical structures and animation workflows. The molecule library accepts SMILES input and provides 3D previews, while chemical image recognition supports SMILES and MOL export. Integrations with PubChem, the NCI/CADD Chemical Identifier Resolver, and RDKit.js support structure-related workflows. Export options extend the tool beyond the browser: animations can be sent to Blender, and reactions can be exported as animated SVG. These features suit educators preparing demonstrations, students exploring molecular structures, and researchers who need explanatory visuals.
ChemViz3D is best for visualization, diagram creation, and reaction animation rather than laboratory simulation. Its published positioning covers molecular modeling, reaction simulation, and equation tools, but virtual labs are outside its scope. Individual learning and teaching are covered by the free service; institutional, LMS, enterprise, redistribution, and product-integration use requires permission or a separate licence. Choose ChemViz3D when clear chemical animation and export workflows matter most. Choose an alternative when the primary requirement is a virtual laboratory or a broader experimental environment.

- Exports animations to Blender and animated SVG
- Where it doesn't
- It is not a virtual laboratory
- Institutional and LMS use requires permission or a separate licence
- Focused on visualization and animation rather than broader lab workflows
