How it works
From .ifc to answers in three steps
-
STEP 01
Drop your IFC file
Drag it onto the page, or pick it from disk. IFC2x3, IFC4, IFC4x3 and .ifczip — any size your device can hold.

.ifc · .ifczip -
STEP 02
Parsed locally, with WebAssembly
The IFC engine runs inside your tab. Nothing is sent to a server — close the page and nothing persists.

No artificial limits
Most online IFC tools upload your model. We never do.
Because processing happens on your machine there is no server to protect, no queue to wait in and no reason to cap file sizes or daily conversions. Your model stays confidential by design — not by policy.
How local processing works →Premium is coming — permanent share links, batch conversion, ad-free.
The viewer and every converter stay free and local. Premium adds what only a server can do.
FAQ
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.
