Convert SKC to another file type
To convert your SKC file to another format, you need BIOVIA Draw or other Vector Image software.
Convert a file to SKC
To convert other file formats to the "Molecular Structure Diagram" file type, you need software like BIOVIA Draw or a similar tool.
About SKC files
The .skc file extension is primarily a Chemical Structure Sketch created by BIOVIA Draw (formerly known as Symyx Draw and ISIS/Draw). These files contain 2D vector representations of molecular structures, chemical reactions, and associated metadata used heavily in pharmaceutical and materials science research.
Users commonly struggle with issues with .skc files due to their proprietary nature. Unlike open formats, they require specific, often expensive industry software like BIOVIA Draw or legacy Symyx viewers to open. They cannot be viewed in standard browsers or pasted directly into Microsoft Word without first exporting them, creating a bottleneck for researchers trying to share data with colleagues or publish findings. Furthermore, legacy files from the Symyx era may exhibit rendering errors in modern suites.
To ensure accessibility and preservation, conversion is highly recommended:
For Interoperability: Convert to MOL (MDL Molfile) or SDF. These are the text-based industry standards supported by virtually all cheminformatics tools, including ChemDraw.
For Publication & Print: Convert to PDF or EPS to maintain vector scalability for high-resolution academic papers.
For Web & Office: Convert to PNG or JPG for easy embedding in presentations and web pages.
*Note: A smaller percentage of .skc files may be BIM classification files used by Solibri or game data files. If your file is not a chemical structure, it is likely one of these binary formats.*
Convert.Guru analyzes your SKC file, detects the exact format, and lets you read the text inside.
If you want to convert SKC file to CSV, JSON, XML, YAML, YML, TOML, INI, CFG, CONF, DAT, DB or SQL, you can use BIOVIA Draw or similar software from the "Chemical Structure Sketch" 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 SKC, try BIOVIA Draw or another comparable tool in the "Chemical Structure Sketch" category.
The SKC 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 SKC converter.
