Free Online SKP to OBJ Converter
SKP and OBJ solve different problems. SKP is SketchUp's native format, widely used in architecture and interior design.
Converting to OBJ makes sense when it stays editable in DCC tools.

How to convert SKP to OBJ
Open the original file
Use the application that created this file.
Export a supported mesh
Export OBJ, GLB or STL; include the material and image files where needed.
Choose another converter
Select a working conversion from the catalogue. This page cannot run the requested conversion.
Why choose this converter
Capability explained
This format requires an exporter or native CAD/DCC application that is not available here. Conversion controls stay disabled.
Supported alternatives
Use GLB for web models, OBJ with companion files for material exchange, or STL for geometry-only printing.
What changes in this conversion
- Unit information will be dropped.
- The result is a triangle mesh, so exact analytic surfaces become faceted.
What Is a SKP File? / OBJ
SKP
SKP is SketchUp's native format, widely used in architecture and interior design. Even when a model looks solid it is frequently made of open, non-manifold surfaces, which matters a great deal if you intend to print it.
- Dominant in architecture and interior design
- Carries materials, textures and units
- Easy to author quickly
- Proprietary with no Python reader
- Models are often not watertight
- Free web version cannot export everything
OBJ
OBJ is a plain-text geometry format from Wavefront. It stores vertex positions, texture coordinates, normals and faces, and references a companion .mtl file for materials and texture maps. Because it is text, it is human-readable and trivially editable, but also noticeably larger than binary alternatives.
- Readable and editable as text
- Supports materials and texture maps via MTL
- Broad support in DCC tools
- Needs the .mtl and texture files to look right
- Large file size for dense meshes
- No animation, no units, no scene graph
SKP vs OBJ
| Property | SKP | OBJ |
|---|---|---|
| Encoding | proprietary binary | text |
| Colour | Yes | Yes |
| Texture maps | Yes | Yes |
| Materials | Yes | Yes |
| Animation | No | No |
| Units | Yes | No |
| Best for 3D printing | Yes | Yes |
| Best for the web | No | No |
| Best for game engines | No | Yes |
Before you convert
- Confirm the source really is SKP — a renamed file will not parse.
- Check the bounding box in the preview; conversion does not fix a wrong scale.
- Decimate dense meshes before converting if the target is a slicer.
Common problems
The upload is rejected
Check the file really is SKP and is under 50MB.
The preview is empty
The file is probably corrupt or uses an unsupported feature. Re-export it from the source application.
The result looks different from the original
Read the format notes above — some loss is inherent to the target format, not a conversion error.
Frequently Asked Questions
Can I convert SKP to OBJ here?
This native CAD/DCC conversion requires an installed CAD kernel or original application. Export a supported mesh from the original application, or choose another output format.
Is an account or payment needed?
No. Available conversions are free and do not require an account.
What is the file size limit?
50 MB combined, with at most one model and 63 companion files.
Will materials and textures survive?
Basic materials and embedded textures are preserved where supported. Include MTL/BIN/images with the source; inspect the result for differences. Textured OBJ downloads include companion resources in a ZIP.
Are animation and rigs preserved?
No animation or rig preservation is promised. Browser conversions export static meshes; check proprietary material features and real-world scale in the result.
Are uploaded models published?
No. Conversion does not add models to the public gallery. Browser USDZ export stays local; server conversions use temporary download files.
