Question 1

Is the IFC viewer really free?

Accepted Answer

Yes. No account, no registration, no trial period and no limit on how often you open it.

Question 2

Is my IFC file uploaded anywhere?

Accepted Answer

No. The file is read and converted inside your browser, on your own machine. It never leaves your device and never reaches a server.

Question 3

Which IFC versions are supported?

Accepted Answer

IFC2x3 and IFC4 — the two versions Archicad, Revit, Allplan, Tekla and Vectorworks export.

Question 4

Do I need to install anything?

Accepted Answer

No. The viewer runs in the browser. A current Chrome, Edge, Firefox or Safari is enough, on a laptop or a tablet.

Question 5

How large can the file be?

Accepted Answer

That is decided by your device's memory, not by a limit we impose. Models of a few hundred megabytes open on an ordinary laptop.
