  • Convert Next.js HTML to PDF and send as email attachment
    It might be easiest to use something like api2pdf.com to convert the HTML to PDF using a simple REST API call instead of trying to wrangle wkhtmltopdf or headless chrome inside serverless functions on Netlify or Google Cloud. That can often be a real hassle. Source: about 4 years ago

  • wkhtmltopdf - Convert HTML to PDF
    I run api2pdf.com and we support both wkhtmltopdf and Headless Chrome. Wkhtmltopdf supports a few interesting tidbits that Chrome does not yet (like automatic table of contents generation). Source: over 5 years ago
