This guide shows how you can get the PDF data as an ArrayBuffer https://www.pdftron.com/documentation/web/guides/saving-updated-pdf/

That code goes on to create a Blob, but you can stop at this line where it’s an ArrayBuffer
const data = await doc.getFileData(options);

Then you could use an approach like this to convert the ArrayBuffer to base64 javascript - ArrayBuffer to base64 encoded string - Stack Overflow
