GroupDocs.Conversion Demos are applications that demonstrate powerful features of GroupDocs.Conversion for Java⁠ distributed as Docker images. Convert DOCX, PDF, PPT, XLS, and over 50 document formats without additional dependencies. Use these images as-is or customize and integrate them into your own project.

Note: without a license the application runs in trial mode. Purchase a license⁠ or request a temporary license⁠.

⁠Security Notice

These Docker images ship sample/demo applications — not production-ready services.

• Intended for local development and evaluation only
• Demo defaults enable upload, browse, and download; no authentication is included
• Do not expose port 8080 to untrusted networks without authentication, a reverse proxy, path validation, and other controls required by your organization
• For production, use the GroupDocs.Conversion library⁠ and implement your own secure document storage and API layer

# Open http://localhost:8080/conversion/ in your browser.

Bind volumes for sample files and license:

docker run -p 8080:8080 --name conversion --rm \

  -v "C:/Licenses/:/home/groupdocs/app/Licenses" \
