Thanks for tracking the request. I commented on the GitHub issue and will keep track of it there!

I am generating a PDF in Node.js using the jsreport Chrome-PDF recipe. I load an external HTML file and use that as the template for the report, and then pipe the generated report back to the browser. My setup looks like this:

await jsReport.init()

try {
  const out = await jsReport.render({
    template: {
      content: html,
      engine: 'handlebars',
      recipe: 'chrome-pdf',
      chrome: {
        format: 'Letter',
        printBackground: true,
        marginTop: '0.25in',
        marginRight: '0.5in',
        marginBottom: '0.25in',
        marginLeft: '0.5in'
      }
    },
    data: {
      myData: myData
    }
  })

  return out.stream.pipe(res)
} catch(err) {
  return res.status(500).send(err)
}

The PDF loads in the browser and looks great! However, when I save the report, the file comes out to roughly 25 MB. There are a few images in the rendered PDF, but this is obviously way larger than it needs to b e.

I can take the file and run it through a service like Smallpdf or Acrobat, and the file comes out to under 200 KB. Is there a way that I can reduce the initial file size before streaming it to the client? I'd like to avoid my clients having to use external software each time they generate a report, and I would also like to avoid having to use a third-party API to do the compression at a fee.
