Kendo pdf viewer canvas in my implementation but not in demo

[Vadim]

Hi! I am using kendo pdf viewer. The issue i have is that component behind the scenes is creating a canvas. This is not allowing me to ctrl + c. I am not sure why is this happening to me but not in the demo page. Do you have any clue what's happening ?

  <kendo-pdfviewer

    *ngIf="isPdfViewerVisible && pdfSource"

    [url]="pdfSource"

    style="height: 100%; width: 100%"

    [tools]="tools"

  ></kendo-pdfviewer>

Hello Vadim,

The Kendo UI for Angular PDFViewer component renders PDF pages using a canvas element, which is a standard approach for displaying PDFs in web applications. Rendering content as a canvas means that the text is drawn as an image, so native browser text selection (such as highlighting and copying with Ctrl+C) is not available.

However, there is another element that holds the text so that the user can select and copy it:

In the official demos, the PDFViewer might use the [data] input with a Base64-encoded PDF or a PDF file that includes selectable text layers. Not all PDFs are created equally—some do not contain selectable text, which can also affect selection behavior.

In case the observed behavior persists, provide more details and exmaple that reproduce the problem. Thank you.

Regards,
