About SKP (SketchUp)

SketchUp model — header inspection only.

SKP is SketchUp's proprietary CFB-style container format. There's no open-source JavaScript or WebAssembly reader for SKP geometry — the SDK Trimble ships is C++ only. We surface the version banner, magic bytes, and embedded text runs so you can verify what's inside without installing SketchUp. To view the geometry, open the file in SketchUp's free web app and export to glTF, OBJ, or Collada — then open that file here.

FAQ
Can this viewer render the 3D model?
No. SKP geometry is locked behind Trimble's proprietary SDK and there's no working JavaScript or WebAssembly reader. The viewer shows the header, version, and any embedded strings so you can confirm the file is valid.
How do I view the geometry then?
Open the .skp file in SketchUp Free (the web version is free with a Trimble account), then File → Export → glTF, OBJ, Collada, or STL. Drop the exported file into our matching viewer and the geometry will render in-browser.
Is my file uploaded?
No. The .skp is parsed entirely in your browser. Nothing is sent to a server.
Which SKP versions are recognized?
We recognize the version banner on files from SketchUp 8 through 2024. Older files (SKP 6 and earlier) use a different magic and may show as 'unknown'.
