Open IFC files online — free, private, instant

You received an .ifc file and you need to see what is inside — without installing Revit, requesting a license, or waiting for a heavyweight desktop suite to boot. This viewer opens Industry Foundation Classes models straight in your browser. Drop the file above and the building appears in 3D in seconds: orbit around it, zoom into details, and check what the model actually contains before you take it into your own tools.

Unlike most online BIM viewers, your file is never uploaded. The IFC parser runs as WebAssembly inside your browser tab, converts the model to an efficient geometry format locally, and renders it with WebGL. Close the tab and nothing persists anywhere. That makes it safe for confidential projects: there is no server copy, no processing queue, and no terms-of-service fine print about your intellectual property — the model simply never leaves your machine.

How it works

1. Drop your file. Drag an .ifc or .ifczip into the viewer, click Open IFC file, or load one of the sample models. Files exported from Revit, ArchiCAD, Tekla Structures, Allplan, Vectorworks or any IFC-compliant tool will work.
2. Watch it parse locally. A progress bar tracks the conversion. A 10 MB model typically takes a couple of seconds; a 100 MB structural model may take a minute — the speed depends on your machine, not on a server queue.
3. Explore in 3D. Orbit with the left mouse button, pan with the right, zoom with the wheel. Navigate the spatial tree, click any element for its properties and Psets, cut section planes, measure distances, take PNG snapshots — or load a second model on top to review a federation. The status bar shows the file name, the detected IFC schema version and the number of items in the model.

What is an IFC file, and why a dedicated viewer?

IFC (Industry Foundation Classes) is the open, vendor-neutral exchange format for BIM — the format architects, engineers and contractors use to hand over models between different software. It is an ISO standard (ISO 16739) and the backbone of openBIM workflows. The catch: IFC files are data-rich but not directly viewable. Authoring tools can import them, but a full BIM suite is expensive, slow to install, and overkill when all you need is to look at a model, verify a delivery, or show it to a client.

A browser viewer fills exactly that gap. Site managers can open the coordination model on a laptop in the field trailer. Clients can review the design without any software knowledge. Engineers can quickly confirm that an export contains the right storeys, elements and revisions before importing it into analysis software. And because this viewer reads the schema directly, it tells you at a glance whether you received an IFC2x3 or IFC4 file — a detail that regularly decides whether an import will succeed downstream.

Built for real project files

This viewer is engineered for the files you actually receive on projects, not just tidy demo models: multi-storey buildings, structural models with tens of thousands of beams and fasteners, and MEP-heavy coordination files. Geometry is streamed into the scene with level-of-detail tiles, so navigation stays responsive even with very large models. Memory is fully released when you load the next file, so you can review a batch of deliverables one after another in the same tab. The viewer is part of a full suite following the same rule — free, in your browser, and no upload: export the model's data with IFC to Excel, convert its geometry with IFC to glTF, or search every property without 3D in the IFC properties explorer.
