IFC Viewer — Open and Preview BIM Models Online
Open and preview .ifc BIM (Building Information Modeling) files on any device. Convert any IFC to a shareable PDF in one click — no Revit, no ArchiCAD, no install.
IFC (Industry Foundation Classes) is the open BIM exchange format used by Revit, ArchiCAD, Tekla, Allplan, Bentley OpenBuildings, and most other architecture, engineering, and construction tools. Even though the spec is open, no everyday viewer — macOS Preview, Adobe Reader, Google Drive, Outlook attachments, browser tabs — knows how to render an IFC. The simplest cross-device way to see what is inside one is to convert the model to a PDF that captures key views, schedules, and dimensions, then open the PDF on any device. Converter.Plus handles the conversion server-side and deletes both the input IFC and the output PDF within 15 minutes.
In-browser IFC viewer — coming soon
We're building a private, browser-side viewer for IFC files. In the meantime, the fastest way to preview a IFC on any device is to convert it to PDF and open the PDF — no install required.
How to view a IFC file today
- Convert the IFC to PDF: Open the IFC-to-PDF converter (or export a PDF from your BIM tool of choice), drop the .ifc file, and download the resulting PDF.
- Open the PDF on any device: Use any PDF reader — macOS Preview, Adobe Reader, your browser, or your phone's share-sheet preview — to open the PDF.
- Share with stakeholders: Email the PDF to clients, contractors, or plan reviewers without forcing them to install a 4 GB BIM tool.
- Round-trip back to source (optional): For full BIM editing, open the original .ifc in Revit, ArchiCAD, or any IFC-compatible BIM tool.
Why preview IFC files this way
- ✓Works on any device with a PDF reader — Mac, Windows, iOS, Android, Chromebook, Linux — no BIM tool install needed.
- ✓PDF output is a shareable, paginated representation of the model — perfect for email, e-signature, and client review.
- ✓Works for IFC2x3, IFC4, and IFC4.3 inputs from Revit, ArchiCAD, Tekla, Allplan, OpenBuildings, and other BIM tools.
- ✓Free for everyday use — share BIM-derived plan sheets with clients, contractors, and reviewers without a 4 GB Revit install.
- ✓Files auto-delete from our servers within 15 minutes — nothing retained, no account required.
- ✓Faster than asking the architect to re-export and re-share a PDF every time you need a quick look.
About the IFC format
IFC (Industry Foundation Classes) is the open, ISO-standardised exchange format for BIM (Building Information Modeling) data, maintained by buildingSMART International. It encodes a building or infrastructure model as a structured graph of objects — walls, slabs, beams, columns, doors, windows, spaces, schedules, and the relationships between them — alongside materials, properties, and georeferencing. IFC2x3 (2007), IFC4 (2013), and IFC4.3 (2024) are the most common revisions in the wild.
Despite being an open standard, IFC files are not openable by any everyday viewer. macOS Preview, Adobe Reader, image viewers, document apps, and email clients cannot render them. The pragmatic alternative for everyday viewing — especially on a Mac, phone, tablet, or stripped-down work laptop — is to convert key views from the IFC to a PDF and open the PDF. PDFs are universal, vector, zoom-friendly, and supported by every device made in the past two decades. That is exactly what this page helps you do.
Frequently Asked Questions
Privacy & trust
- •IFCs are uploaded only for the duration of the conversion and forwarded to the conversion provider via TLS.
- •Files auto-delete from both our server and the conversion provider within 15 minutes; no long-term storage.
- •No account, no email, no payment information required for everyday viewing.
- •Errors are surfaced verbatim — quota issues, malformed IFC, or unsupported schemas produce a clear message rather than a degraded preview.
