Extract text from CirclePack data files (CIRCLES)
To convert CIRCLES data files to another format, you need CirclePack or other Data software.
To convert other file formats to the "Geometry Data File" file type, you need software like CirclePack or a similar tool.
A .circles file is primarily a mathematical data container used by CirclePack, a software package dedicated to the study of circle packings and discrete conformal geometry. These files store the precise geometric arrangement of tangent circles, including center coordinates, radii, and triangulation connectivity (the "complex"). While essential for academic research in conformal mapping, the format is highly specialized and problematic for general distribution.
Because CirclePack is a niche academic tool (often running as a legacy Java application), opening a .circles file typically requires installing specific runtime environments that many users lack. Furthermore, you cannot view these geometries natively in web browsers or standard image editors like Adobe Photoshop. For researchers publishing papers or students sharing data, this proprietary lock-in is a significant hurdle. The most practical workflow is to convert .circles files into accessible formats: SVG or PDF for vector-perfect scaling in academic papers, PNG for quick web previews, or CSV to extract the raw numerical data for analysis in Microsoft Excel.
Convert.Guru analyzes your CIRCLES file, detects the exact format, and lets you read the text inside.
Users also converted TAH, LXF and S3D files.
If you want to convert CIRCLES file to , you can use CirclePack or similar software from the "Mathematical Data Storage" category. In the File menu, look for Save As… or Export….
To convert files to CIRCLES, try CirclePack or another comparable tool in the "Mathematical Data Storage" category.
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 CIRCLES converter.
