License Information

Document Solutions PDF Viewer supports the following types of license:

Evaluation License
Production License

Evaluation License

You can obtain a free 30-day evaluation key by contacting us.sales@mescius.com. The evaluation version is fully functional and displays the below watermark:

'Powered by Document Solutions PDF Viewer. Your temporary deployment key expires in [x] days.'

The evaluation key will allow you to develop and test your application on both your development machine and staging server for 30 days.

Production License

Once you purchase the license, you will receive a license key that removes all watermarks. The production license offers two types of licenses: standard and professional.

Standard License

Included with every DsPdf license purchase. This deployment includes all features of the viewer except those that require the viewer to use SupportApi property (i.e., connect the viewer to DsPdf on the server or DsPdfViewer/Wasm). For more information, see View PDF.

Professional License

Includes all the features of the Standard license in addition to features that require the viewer to use the SupportApi property (i.e., connect the viewer to DsPdf on the server or DsPdfViewer/Wasm). For more information, see Edit PDF.

Please refer to DsPdfViewer License Options to know more about Standard and Professional Viewer License.

How to apply your license key

To apply evaluation/production license in DsPdfViewer, set DsPdfViewer licensed deployment key to DsPdfViewer.License property before creating and initializing DsPdfViewer:

	Copy Code
<script> // Add your license DsPdfViewer.LicenseKey = 'your_license_key'; // Add your code window.onload = function(){ const viewer = new DsPdfViewer("#viewer1", { file: 'helloworld.pdf' }); viewer.addDefaultPanels(); } </script>

Copy Code

<script>
     // Add your license
     DsPdfViewer.LicenseKey = 'your_license_key';
     // Add your code

      const viewer = new DsPdfViewer("#viewer1", { file: 'helloworld.pdf' });
      viewer.addDefaultPanels();
     }
    </script>
