One geometry engine, many tools

Vertessia isn't just a converter — it's a 3D geometry toolkit. Mesh conversion is live today; reconstruction, more mesh algorithms and the API are on the way.

Mesh conversion
Convert between STL, OBJ, PLY, 3MF, GLB, glTF and STEP → mesh, with instant 3D preview. Free.
Soon
◆
CAD reconstruction
Turn scanned meshes into editable STEP B-rep — real surfaces, not facet translation. The paid core.
Soon
⊹
Mesh algorithms
Hole filling, simplification, remeshing and repair — clean up scans and prints before you use them.

Build with the API

The same engine behind this web app, as a REST API — convert, reconstruct and process geometry from your own code. Usage-based pricing, prepaid credits, webhooks for long jobs. Coming soon.

POST /v1/convertcoming soon
curl -X POST https://vertessia.com/v1/convert \
  -H "Authorization: Bearer $API_KEY" \
  -F "file=@scan.stl" \
  -F "target=step"

Pricing

Mesh conversion is free — paid tiers coming soon

Convert between STL, OBJ, PLY, 3MF, GLB, glTF and STEP for free, forever. The paid tiers below unlock high-quality CAD B-rep reconstruction (mesh → editable STEP) — the genuinely hard part — and go live once the engine is ready.
