Rendering & PDFs

Invio renders HTML using your chosen template, then turns it into a PDF with wkhtmltopdf.

HTML rendering

Section titled “HTML rendering”
  • Uses selected template (settings.templateId) and business settings.
  • Highlight color is optional.

PDFs

Section titled “PDFs”
  • Generated with wkhtmltopdf using the same HTML you see in the app.
  • Private and public HTML/PDF share the same rendering pipeline; the difference is auth and caching headers.
  • If PDF generation isn’t available, the HTML view works as a fallback.
