Share a SketchUp (.skp) File Online — No Install for the Recipient

Open a SketchUp (.skp) file online free — no licence, no install. Export to OBJ or GLB, then view, share by link and embed a .skp model in 60 seconds.

This guide is for SketchUp users who want to share a model with someone who doesn't have SketchUp — not for opening a .skp you received without ever having SketchUp yourself (the .skp format can only be exported from SketchUp itself; if that's your situation, see the note near the end of this guide). If you do have SketchUp: export your model to a universal 3D format — OBJ, DAE or GLB — then upload that file to a browser-based viewer such as OmniView 3D. You get an interactive 3D model and a shareable link in about 60 seconds, viewable by the recipient with no SketchUp licence and nothing to install on their end. This guide walks through the export from both SketchUp Free and SketchUp Pro, and compares the free SketchUp viewers available in 2026 for architects, interior designers and construction teams.

Why you can't open a .skp file directly

The .skp extension is Trimble's proprietary SketchUp format. Unlike neutral formats, it is not designed to be read outside the SketchUp ecosystem, so a plain browser or a generic 3D viewer cannot open it as-is — you first export to an interchange format. SketchUp is one of the most widely used 3D tools in architecture, engineering and construction (AEC): Trimble announced that SketchUp surpassed one million active subscribers in November 2024, which is exactly why so many .skp models end up needing to be shared with clients, owners and contractors who do not run SketchUp themselves.

That sharing pressure is real and measurable. In the same announcement, Trimble reported that more than 650,000 users had shared 1.7 million SketchUp links, opened by 3.8 million people — evidence that the bottleneck in a SketchUp workflow is rarely the modelling and almost always getting the model in front of someone who doesn't have the software. A web viewer removes that bottleneck.

How to open and share a SketchUp file without SketchUp

The workflow is the same in every case: export from SketchUp to a universal format, then upload to OmniView 3D and share the link. The export step depends on which edition you use.

From SketchUp Free (web version)

1. 1Open your project in SketchUp Free (app.sketchup.com)
2. 2File → Download → OBJ or DAE (Collada)
3. 3Upload the OBJ or DAE to OmniView 3D — see the online OBJ viewer if you want to preview it first
4. 4Share the interactive link — viewable in any browser, no install required

From SketchUp Pro

1. 1File → Export → 3D Model
2. 2Choose OBJ, FBX, or glTF/GLB (SketchUp Pro 2021+)
3. 3Upload to OmniView 3D
4. 4Share the link or embed it via iFrame on your website

If your export lands as a Collada .dae or a GLB, you can view and share it exactly the same way — OmniView 3D reads them natively, and you can also convert a DAE to GLB or an OBJ to GLB online to get the lightest, most web-friendly version before you send it.

SketchUp viewers compared: which free option to use

Trimble ships its own tools, and there are several browser viewers. They differ mostly on one axis: whether they are built for sharing a model with someone outside your account, or just for looking at it yourself.

In short: SketchUp Viewer and SketchUp for Web are the right tools to open a native .skp yourself, but both keep you inside the Trimble account system. To hand a model to a client, a bank, a planning committee or a contractor with a single link and nothing to install, a neutral web viewer like OmniView 3D is the simpler path — and it hosts your models in the EU under GDPR, with your files never used to train an AI.

What you can do with a SketchUp model in OmniView 3D

• Architecture: share a building or house model with a building owner, bank or planning committee for approval or financing
• Interior design: present a 3D concept to a client without bringing a laptop or a headset
• Construction: hand 3D plans to contractors and subcontractors on site, on their own phones
• Real estate: embed an interactive 3D tour on a sales page or in an email
• Urban planning: submit a project model to a municipality or planning commission via a link
• Furniture and millwork: show a custom piece to a client before fabrication

Because the model runs in the browser, the same link works on desktop, tablet and phone. For AEC teams specifically, this is often the difference between a decision made in the meeting and a decision deferred — a point we cover in our guide to the 3D viewer for architects. The broader move to cloud tools reinforces it: the cloud-based CAD segment was valued at about USD 1.65 billion in 2024 and is forecast to reach USD 3.43 billion by 2032, an 8.9% CAGR, per Credence Research, driven by exactly this need for browser-based collaboration.

I received a .skp file and don't have SketchUp — what now?

The steps above require SketchUp to do the export, since .skp can only be opened and converted from within SketchUp itself — there is no browser-based way to read a raw .skp file directly, on OmniView 3D or any other web viewer. If you don't have SketchUp, your two options are: ask whoever sent you the file to export it to OBJ or GLB and share that (or the OmniView 3D link) instead, or install Trimble's free SketchUp Viewer app (iOS/Android), which opens native .skp files.
