Convert GL files online for free
The converter easily converts your GL file to various formats - free and online. No Blender or extra software needed.
The converter also works in reverse, so you can convert other Vector Image formats to GL with high quality output.
The .GL extension represents a collision between two very different eras of computing: the GRASP Animation (legacy multimedia) and the HPGL Plotter File (industrial CAD).
1. GRASP Animation (Legacy Video):
If your file is a retro animation, it is a GRASP Library (Graphical System for Presentation), a format popular in the DOS era (early 1990s) for creating software demos and tutorials. These files are technically containers that bundle multiple images (PIC, CLP) and script commands into a single executable-like movie. Modern media players like Windows Media Player or QuickTime cannot open them. To view these nostalgic clips, you must convert them to a modern standard like MP4 or GIF.
2. HPGL Plotter File (Vector CAD):
If your file comes from an engineering or design context, it is likely a Hewlett-Packard Graphics Language file. These are plain-text vector files containing instructions (like PU for "Pen Up" or PD for "Pen Down") used to control pen plotters and vinyl cutters. While efficient for machinery, they are problematic for office use because they cannot be viewed in standard web browsers or document readers. Users frequently need to convert these to PDF for client proofs, DXF for editing in AutoCAD, or SVG for web publishing.
3. Game Archives:
Less commonly, .GL files serve as data archives for specific games (e.g., Mandy's World of Colours or Star Crusader). These are proprietary containers often unreadable outside the game itself.
Use Convert.Guru to open and convert your GL file.
Users also converted GRASP, LRV, PKZ, SAZ and SDU files.
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 GL converter.
