eml-render-pdf

Render EML emails to PDF exactly as they appear by letting Chromium do the HTML/CSS layout, while keeping inline images and appending PDF attachments.

Why this approach

• Uses the email’s original HTML/CSS: no regex stripping, minimal overrides.
• Inline CID/data images are rewritten to data URLs so Chromium can render them.
• PDF attachments are appended after the rendered email body (like the old tool).

Requirements

• Node 18+

Install

cd "eml to pdf-render"
npm install

Usage

node src/convert.js /path/to/email.eml /path/to/output.pdf

• If output.pdf is omitted, it writes to ./output/<email-name>.pdf.

Notes

• Relies on Playwright’s headless Chromium to keep layout fidelity.
• Minimal CSS is injected only to reduce default margins and ensure images scale down; the email’s own styles stay in place.
• CID images in attachments are converted to data URLs and rendered inline.
• PDF attachments are merged after the body PDF; other attachment types are ignored.
