What is a SKM file?
The .SKM file extension primarily identifies a SketchUp Material File developed by Trimble for their SketchUp software. These files contain textures, colors, and material definitions applied to 3D models. Internally, these .SKM files use the standard ZIP format to package XML metadata and texture images (like JPG or PNG) into a single file.
Other uses for SKM files
While 3D materials represent the most common use, a .SKM file might also be a mobile phone video file stored in MP4 or 3GP format. These are frequently associated with SK Telecom devices. Less commonly, the extension identifies a compressed audio file or karaoke song encoded by Nellymoser.
How to open SKM files?
For 3D textures, you can import them directly into SketchUp. If you need to access the raw texture image, you can change the .SKM file extension to .ZIP and extract it using archive utilities like 7-Zip. For video or audio files, media players like VLC media player can typically play the content.
Summary
Because the .SKM extension has multiple possible meanings, we recommend using viewer.online/skm to identify the actual format of your file. viewer.online/skm analyzes .SKM files to identify their exact format and creator software, shows which programs can open the file, and usually previews it. Because SketchUp Material .SKM files use the known ZIP format, viewer.online/skm can safely open and display them online, eliminating compatibility problems.
