Free Online SKP Viewer (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. See our Circadian Sky product model for an example.
How to View an SKP File Online

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.
Load from URL
Share a link with ?url= to open a specific SKP file automatically.
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
This viewer runs entirely in your browser using a custom-built JavaScript parser. Your SKP file is never uploaded to any server. We may use standard site analytics, but your 3D model data stays private.
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.

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+).
▶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.
