EML to PDF Converter — Save Email Messages as PDF Free

This converter parses EML (Electronic Mail) files — the standard RFC 2822 text format used by email clients like Outlook, Thunderbird, and Apple Mail. The parser extracts email headers (From, To, Cc, Subject, Date) by matching header patterns in the unfolded header section, handling multi-line header continuation per RFC 2822 rules.

For the email body, the parser handles MIME multipart messages by detecting the Content-Type boundary parameter and splitting the message into parts. It prioritizes text/plain content for the cleanest PDF output, falling back to text/html with HTML tag stripping to preserve readable text. The tool also handles common Content-Transfer-Encodings: quoted-printable (decoding =XX hex sequences and removing soft line breaks) and base64 (using atob() for binary-to-text decoding).

The parsed email is rendered into a PDF using jsPDF with structured formatting: the subject appears as a bold title, followed by header fields in a smaller font with grey coloring, a separator line, and then the body text in standard formatting with proper pagination. This creates a clean, professional document suitable for archiving, legal evidence, or record-keeping purposes.
