Frequently asked questions
Is it safe to open my IFC files here?
Yes. Your files are parsed locally in your browser using WebAssembly — they are never uploaded to any server. Close the tab and nothing persists.
Which IFC versions are supported?
IFC2x3, IFC4 and IFC4x3, plus compressed .ifczip files.
Is there a file size limit?
No hard limit. Models up to roughly 300 MB work well depending on your device's memory; we show a heads-up above 150 MB.
Do I need to create an account?
No account, no email, no install. Open the page, drop your file, done.
Is this viewer open source?
The 3D engine is built on the open source BIM ecosystem — That Open Company's components and the web-ifc parser, the same foundations trusted across the openBIM community. IFCfiles itself (the tools, the conversion pipeline and everything around them) is our own work on top of that foundation.
