Convert SURF to another file type
To convert SURF surfaces to another format, you need Amira-Avizo or other 3D software.
Convert a file to SURF
To convert other file formats to the "Scientific Visualization Mesh" file type, you need software like Amira-Avizo or a similar tool.
About SURF files
The .SURF file extension is a classic example of a filename collision, primarily representing Amira-Avizo 3D surface geometry or Nemetschek Allplan surface textures.
For scientists and researchers, the Amira .SURF file (often called HyperSurface) contains triangular mesh data used to visualize complex 3D structures like biological tissue or geological formations. A major limitation here is the proprietary nature of the Amira-Avizo software; sending this file to a colleague without the software renders it useless. These files are not natively supported by standard 3D tools like Blender or typical 3D printers. To make the geometry usable, you generally need to convert it to OBJ or STL formats, which universalizes the mesh for editing, printing, or archiving.
Alternatively, if you are an architect using Nemetschek Allplan, the .SURF file is likely a raster-based surface definition used for rendering materials (like brick or wood textures). While these files often contain standard TIFF image data, they are locked into the CAD environment. Converting these to standard PNG or JPG files allows you to use the textures in other rendering engines or simply view them without launching a heavy CAD suite.
Less commonly, .SURF files act as simple configuration text files for simulators like OMSI or data exports from Anton Paar analysis tools. In these cases, the file is virtually inaccessible to standard viewers unless you recognize it as XML or plain text.
Convert.Guru analyzes your SURF file, detects the exact format, and lets you read the text inside.
If you want to convert SURF file to CSV, JSON, XML, YAML, YML, TOML, INI, CFG, CONF, DAT, DB or SQL, you can use Amira-Avizo or similar software from the "3D Surface Geometry" category. In the File menu, look for Save As… or Export….
To convert DBF, XML, SQLITE, XLSX, SQL, TSV, ACCDB, YAML, MDB, CSV, ODS or JSON files to SURF, try Amira-Avizo or another comparable tool in the "3D Surface Geometry" category.
The SURF Converter Story
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 SURF converter.
