Export your diagrams and tables into high-quality image files for reports, presentations!

1. Exporting via the Graphical Interface

The easiest way to export diagrams is directly through the Astah workspace.

  1. Navigate to [File] → [Export Image]
  2. Select your scope:
    • Current Diagram: Exports only the diagram currently active in your editor.
    • Multi Diagrams: Opens a selection window where you can batch-select diagrams and tables.
      Export Image

  3. Choose your destination folder. Astah will automatically use the Diagram Name as the filename.

TIPS: To adjust the default resolution (DPI) or background transparency, go to [Tools] → [System Properties] → [Image Export].
System Properties - Image Export

2. Command-Line Export

You can also export images directly via command-line.

Basic Command Syntax

Use the -image option followed by the diagram type and source file.

Available Format

PNG, JPEG, EMF or SVG. By default, images are exported in PNG format unless specified otherwise.

If you are using Astah SysML:

[Windows] Export all the diagrams of the C:\input\ABC.axmz .file to C:\output in PNG

astahsyml-command.bat -image all -f C:\input\ABC.axmz -o C:\output

[macOS] Export all the diagrams of ~/input/ABC.axmz file to ~/output in JPEG

astahsysml-command.sh -image all -f ~/input/ABC.axmz -o ~/output -t jpg
