GroupDocs.Viewer Demos are applications that demonstrate powerful features of GroupDocs.Viewer for Java⁠ distributed as Docker images. View DOCX, PDF, PPT, XLS, and over 170 document formats without additional dependencies. Search and select text from any document. 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.Viewer library⁠ and implement your own secure document storage and API layer

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

Bind volumes for sample files and license:

docker run -p 8080:8080 --name viewer --rm \
  -v "C:/DocumentSamples/:/home/groupdocs/app/DocumentSamples" \
  -v "C:/Licenses/:/home/groupdocs/app/Licenses" \
