Extract text from SPP files
To convert your SPP file to another format, you need Adobe Substance 3D Painter or other 3D software.
To convert other file formats to the "Texture Painting Project" file type, you need software like Adobe Substance 3D Painter or a similar tool.
The .spp file extension most frequently identifies a Substance Painter Project, the native format for Adobe Substance 3D Painter (formerly by Allegorithmic). These files act as containers for complex, non-destructive 3D texturing workflows, storing mesh data, material layers, masks, and brush strokes within an HDF5 structure.
The Challenge: Because .spp files are proprietary working environments rather than final assets, they cannot be opened by standard image viewers, web browsers, or directly imported into game engines like Unity or Unreal Engine. They often exceed hundreds of megabytes in size and require an active Adobe subscription to access. To use the content for games, web, or rendering, users must export the project to standard formats.

A secondary but significant use is the Serif PagePlus Publication file. Since PagePlus has been discontinued and replaced by Affinity Publisher, these documents are often inaccessible.
Convert.Guru analyzes your SPP file, detects the exact format, and lets you read the text inside.

The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our SPP converter.
