About SGM files
The .SGM file extension predominantly denotes a Standard Generalized Markup Language (SGML) document. SGML is an ISO 8879 standard for defining generalized markup languages; it is the parent architecture of both HTML and XML. These files contain plain text structured with tags to describe document elements for enterprise documentation. Another highly common use of the .SGM extension is for Game Boy Advance savestates created by the VisualBoyAdvance emulator, which stores snapshots of the console memory in a compressed GZIP format. To open SGML files, enterprise XML authoring tools like Arbortext Editor by PTC are typically used, though any basic text editor can view the raw markup. Emulator saves are strictly opened by VisualBoyAdvance or its modern forks like VBA-M. Users frequently need to convert .SGM SGML files because modern web browsers and word processors do not natively render raw SGML tags. The format is archaic, overly complex, and heavily relies on external Document Type Definitions (DTDs) just to be readable. VisualBoyAdvance users face equally annoying limits, as .SGM savestates are emulator-specific and rarely load correctly in other GBA emulators like mGBA without careful state extraction. For web publishing, convert .SGM (SGML) directly to HTML or XML. For documentation archiving, convert the styled output to PDF. If you are dealing with a savestate, extracting the compressed GZ data might be necessary to migrate your game progress.
Convert.Guru analyzes your SGM file, detects the exact format, and lets you read the text inside.

The SGM 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 SGM converter.
