Convert ArchiCAD objects or audio (GSM) online for free
The converter easily converts your GSM objects or audio to various formats - free and online. No ArchiCAD or or other 3D software needed.
The converter also works in reverse, so you can convert other "ArchiCAD GDL Object File" formats to GSM without using software like ArchiCAD or a similar tool.
The .gsm file extension primarily represents two entirely different formats: an ArchiCAD 3D library object or a legacy telephony audio recording.
In the architectural design industry, a .gsm file is a Graphic Description Language (GDL) Object. It stores 3D models like doors, windows, and furniture. The major disadvantage of this format is its strict proprietary lock-in. A .gsm 3D model is tightly bound to the Graphisoft ecosystem. You cannot easily open, view, or edit it in standard 3D software, which makes collaboration with non-ArchiCAD users incredibly frustrating. For broader 3D editing and sharing, convert your architectural .gsm files to OBJ, 3DS, or DWG formats.
Alternatively, a .gsm file may be an audio recording encoded in the Global System for Mobile Audio standard. Standardized by the European Telecommunications Standards Institute (ETSI), this format powered voice calls on early 2G mobile networks and legacy US Robotics modems. The obvious drawback of this audio format is its poor quality. It uses aggressive lossy compression at a tiny 13 kbps bitrate, making it unsuitable for anything other than basic human speech. Furthermore, modern web browsers and smartphone media players lack native playback support for it. For reliable web playback and archiving, convert your GSM audio to MP3 or WAV.
Just drag and drop your file here to analyze and convert it - free, online, and without installing expensive CAD tools or outdated audio players.

Users also converted LCF, RFA, 3D, RECORD, GAM, TDE, GMS, FSM, PLA, IFC, MP3, PLN and HIF files.
If you want to convert GSM file to M4A, ALAC or APE, you can use ArchiCAD or similar software from the "3D Object or Telephony Audio" category. In the File menu, look for Save As… or Export….
To convert MIDI, MID or RA files to GSM, try ArchiCAD or another comparable tool in the "3D Object or Telephony Audio" 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 GSM converter.
