Free Online SKP Viewer & Converter (No Signup)
Works in Chrome, Firefox, Safari, and Edge — no plugin required
What Is an SKP File?
SKP is the native file format used by SketchUp, a popular 3D modeling application for architecture, interior design, landscape architecture, and woodworking. SKP files store 3D geometry (faces, edges, vertices), materials, textures, layers, and component definitions.
If you’ve received an .skp file from a designer or architect, you can view it instantly with this free tool — no SketchUp license required. You can also convert your SKP file to GLB, OBJ, STL, or PDF for use in other applications, 3D printing, or documentation.

Export Formats
SKP to GLB (glTF Binary)
GLB is the universal 3D exchange format. Open your converted file in Blender, Unity, Unreal Engine, web-based viewers, AR/VR apps, and Google’s model viewer. Materials and colors are preserved. Ideal for sharing 3D models across platforms.
SKP to OBJ (Wavefront)
OBJ is one of the most widely supported 3D formats. Import your converted file into 3ds Max, Maya, Rhino, Cinema 4D, MeshLab, or any modeling tool. OBJ files contain vertex and face data in a simple text format.
SKP to STL (Stereolithography)
STL is the standard format for 3D printing. Upload your converted file directly to your slicer (Cura, PrusaSlicer, Bambu Studio) or 3D printing service (Shapeways, Xometry). Also used for CNC machining and FEA simulation.
SKP to PDF (Vector Drawing)
Export the current camera view as a clean vector PDF with crisp lines at any zoom level. Includes solid, wireframe, and blueprint render modes. Perfect for presentations, construction documents, and print.

Convert to OBJ
Save as Wavefront OBJ for use in 3ds Max, Maya, Rhino, Cinema 4D, and other modeling tools.
Convert to STL
Export a triangulated STL mesh ready for 3D printing, CNC, or FEA simulation.
Export as PDF
Save the current view as a clean vector PDF — ideal for presentations and documentation.
No Upload Required
Your file is parsed and converted entirely in your browser. Nothing leaves your computer.
V8 to V25+ Support
Supports SketchUp files from version 8 (2010) through the latest releases.
Works Everywhere
Desktop and mobile browsers with WebGL support — no plugin needed.
Drag & Drop
Drop an SKP file anywhere on the viewer to open it instantly.
Embed on Any Site
Add the viewer to your website with a single iframe embed code.
Embed on Your Website
Add this SKP viewer to your own site with a single line of HTML. Use the ?url= parameter to load a specific SKP file automatically.
Supported SketchUp Versions
If your model looks incomplete, try re-saving it in SketchUp 2021 or later for the best compatibility.
Your Files Stay on Your Computer
Both viewing and conversion run entirely in your browser using a custom-built JavaScript parser. Your SKP file stays on your device unless you choose to share it. Viewing, conversion, and export (GLB, OBJ, STL, PDF) all run locally and download directly to your device. Shared files are hosted for 90 days.
If Your SKP File Doesn’t Load
This viewer supports SketchUp files from V8 through the latest versions. If your file doesn’t open or looks incomplete, try these steps:
- 1Re-save in SketchUp 2021+ — The newer VFF/ZIP format uses a more structured binary layout that typically renders better.
- 2Check the file extension — Make sure your file is actually a
.skpfile. - 3Try a desktop browser — Large models may be slow on mobile devices. Chrome or Firefox on a desktop typically gives the best performance.
A sample model loads automatically when you open the viewer — use it to verify your browser is compatible before opening your own file.
Frequently Asked Questions
▶What SketchUp versions are supported?
This viewer supports SketchUp files from version 8 (2010) through the latest SketchUp 2025+ releases. V8–V20 files use the legacy MFC format; V21+ files use the newer VFF/ZIP container format. Both are fully supported.
▶Is this SKP viewer really free?
Yes, completely free with no signup, no watermarks, and no file size limits. Built by Innerscene as a tool for architects and designers.
▶Are my SKP files uploaded to a server?
No. All processing happens locally in your browser using a pure JavaScript parser. Your SKP files never leave your computer — nothing is uploaded, stored, or transmitted.
▶Do I need SketchUp to open an SKP file?
No. SketchUp is not required. This free online viewer lets you open and explore SKP 3D models directly in your browser without any Trimble software.
▶What is an SKP file?
SKP is the native file format used by SketchUp, a popular 3D modeling application. SKP files store geometry (faces, edges, vertices), materials, textures, layers, and component definitions.
SKP is widely used in architecture, interior design, landscape design, and woodworking. The format has evolved from MFC-based serialization (V3–V20) to a modern ZIP-based container (V21+).
▶Can I convert an SKP file to GLB, OBJ, or STL?
Yes. Open your SKP file in the viewer, then click the Export button in the toolbar. You can download the model as GLB (glTF binary), OBJ (Wavefront), STL (for 3D printing), or PDF (vector drawing). The conversion happens entirely in your browser — your file stays on your device unless you choose to share it.
▶Which export format should I choose?
GLB is the best all-around choice — it preserves materials and colors, and opens in Blender, Unity, web viewers, and AR/VR apps.
OBJ is widely supported by professional modeling tools (3ds Max, Maya, Rhino, Cinema 4D).
STL is the standard for 3D printing — upload it directly to your slicer software.
PDF exports the current camera view as a vector drawing, ideal for documentation and presentations.
▶Is the SKP to GLB conversion accurate?
The converter exports all visible face geometry with material colors from the Three.js scene. The output GLB will match what you see in the viewer. For best results, verify the model looks correct in the viewer before exporting. Component instances and textures are included where supported.
▶Can I convert SKP to STL for 3D printing?
Yes. Click Export → .stl to download a binary STL file ready for 3D printing. The STL contains a triangulated mesh of all visible geometry. Open it in your slicer (Cura, PrusaSlicer, Bambu Studio) or upload to an online 3D printing service. Note that STL does not include colors or materials.
▶Does this viewer work on Mac, iPad, or iPhone?
Yes. The viewer runs entirely in your web browser, so it works on macOS (Safari, Chrome, Firefox), iPad, iPhone, and any device with a modern browser and WebGL support. No software download needed.
▶How do I navigate the 3D model?
Orbit: Left-click drag. Pan: Right-click drag. Zoom: Ctrl + scroll wheel. Click “Reset View” to re-center the camera on the model. Touch gestures are supported on mobile devices.
▶Can I load an SKP file from a URL?
Yes. Add ?url=YOUR_SKP_URL to the viewer page URL. The file will be fetched and opened automatically. You can also use the compressed ?d= parameter for shorter links.
▶Why are some faces missing or in the wrong position?
This viewer uses a pure JavaScript parser that reads the binary SKP format directly. Some complex models with deeply nested components, advanced materials, or non-planar faces may not render perfectly.
If your model looks incomplete, try opening the original in SketchUp and saving it as a newer version (2021+), which uses a more structured binary format.
▶What is Innerscene?
Innerscene makes premium artificial skylights — Virtual Sun and Circadian Sky — that bring realistic daylight to windowless spaces. We built this free SKP viewer to help architects and designers working with our product models.
