Convert SketchUp files to OBJ, with textures

How to convert SKP to OBJ

1. Click Choose a .skp file above, or drag the file onto the box.
2. Wait while your browser reads the model and writes the OBJ. Small files take a second or two; a 20 MB house model took about 15 seconds on our laptop.
3. Click Download .zip, unzip it, and import the .obj into your 3D app. In Blender that's File › Import › Wavefront (.obj).

What's in the download

An OBJ on its own only holds shapes. Colors and textures live in a separate .mtl file, and the .mtl points to image files. Plenty of converters hand you the .obj alone, and the model then opens grey. This one packs all three into one zip:

• model.obj: every visible face, triangulated, with texture coordinates and normals.
• model.mtl: one material per SketchUp material, with its color and transparency.
• textures/: the original texture images from the .skp, as JPEG or PNG, under the names they had when they were added to SketchUp where the file recorded one.

What carries over, and what doesn't

OBJ is a simple mesh format, so some SketchUp concepts have nowhere to go:

• Kept: geometry at real-world size, colors, textures and their placement, transparency, and every copy of a component in its place.
• Split, not named: the model is split into objects by component and material, but SketchUp's own group and component names aren't written, and materials get numbered names.
• Not kept: edges and lines with no face, tags as separate layers, scenes, dimensions and text. Hidden geometry is left out, the same way SketchUp leaves it off screen.

How it works

The converter uses the same open-source SketchUp reader as our free SketchUp viewer. It runs inside your browser, unpacks the .skp, places every component where it sits in the model, triangulates each face and writes the result as OBJ text, compressed into the zip. Nothing is sent to a server at any step, which is why it works on client work and drawings under NDA.

To test it, we converted a 20 MB house model saved in SketchUp 2026. The zip came out at 22 MB with 326,385 triangles, 121 materials and 46 texture images.

Other ways to get an OBJ from SketchUp

• SketchUp Pro's own export (File › Export › 3D Model) is the most faithful, since it can keep group names and offers export options. It needs a paid SketchUp subscription.
• innerscene's SKP converter also runs in the browser with no upload, and makes GLB, STL and PDF as well as OBJ. Its page doesn't say whether textures come with the OBJ.
• Convert3D offers far more output formats, including FBX and DWG, if OBJ isn't the format you're after.

Need the model in an older SketchUp instead?

If someone sent you a .skp your SketchUp won't open, OBJ is a lossy detour: you'd get the shapes back without groups, tags or edges. Converting the file to your SketchUp version keeps all of that. Check which version saved it with the SKP version checker, then convert it to an older SketchUp (first file free), or read every way to open a file from a newer version.
