Extract text from OmniGraffle templates (GTEMPLATE)
To convert GTEMPLATE templates to another format, you need OmniGraffle or other Vector Image software.
To convert other file formats to the "Diagram Template File" file type, you need software like OmniGraffle or a similar tool.
The .gtemplate file is a document template created by OmniGraffle, a powerful diagramming and digital illustration application designed exclusively for macOS and iOS. These files store default settings for new diagrams, including canvas dimensions, grid behaviors, stencils, typography rules, and graphic styles. Users rely on these templates in software built by The Omni Group to maintain visual consistency across flowcharts, UI wireframes, and organizational charts.
The main disadvantage of the .gtemplate format is its strict hardware lock-in. Because it is a proprietary, closed-ecosystem format, it requires an Apple device and a paid OmniGraffle license to open natively. Windows users, Linux users, and web browsers cannot natively read or render these templates. This creates severe friction when collaborating in mixed-OS environments or sharing starting points with clients.
To make these designs accessible, you must convert the .gtemplate file to a standard format. The best conversion targets include PDF for high-fidelity document sharing, SVG for scalable vector editing in programs like Adobe Illustrator, or PNG for quick, rasterized web viewing.
Because this file uses specialized, undocumented structures tied to Apple's Core Graphics framework, it is exceptionally difficult to open or convert using generic web tools. Most standard online converters fail to process the proprietary Apple packages. Even if full graphic conversion fails, our analysis can often extract embedded metadata, text strings, or nested standard image files from within the template.
Convert.Guru analyzes your GTEMPLATE file, detects the exact format, and lets you read the text inside.
If you want to convert GTEMPLATE file to SVG, AI, EPS, PDF, JPG, CDR, WMF, EMF, SWF, FLA, XFL or SKETCH, you can use OmniGraffle or similar software from the "Vector Diagram Template Storage" category. In the File menu, look for Save As… or Export….
To convert AFPUB, EPS, FIG, VSD, SKETCH, VDX, AFPHOTO, PDF, AFDESIGN, SVG, VSDX or AI files to GTEMPLATE, try OmniGraffle or another comparable tool in the "Vector Diagram Template 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 GTEMPLATE converter.
