pdf.proxyURL String (default: null)

The URL of the server side proxy which will stream the file to the end user.

A proxy will be used when the browser is not capable of saving files locally, for example, Internet Explorer 9 and Safari.

The developer is responsible for implementing the server-side proxy.

The proxy will receive a POST request with the following parameters in the request body:

  • contentType: The MIME type of the file
  • base64: The base-64 encoded file content
  • fileName: The file name, as requested by the caller.

The proxy should return the decoded file with the "Content-Disposition" header set to attachment; filename="<fileName.pdf>".

Example - set the server proxy URL

<textarea id="editor"></textarea>
        tools: ["pdf"],
        pdf: {
            proxyURL: "/save"
