Why convert an email to PDF
An email saved as an .eml file is awkward to keep or share: it opens in a mail program, depends on that program to display it, and is not a format most people recognize. A PDF is easy to open anywhere, simple to attach, and suited to keeping a record of a conversation, an order confirmation, or correspondence you need to file or submit.
What the PDF contains
EML to PDF reads the message and produces a clean A4 document with the subject as a heading, followed by the sender, recipients, CC and BCC lines if present, the date, and the reply-to address, and then the body of the message. Encoded subjects and names, and messages encoded in quoted-printable or base64, are decoded properly. A footer on each page shows page numbers for longer emails. The conversion runs in your browser, so the email is not uploaded.
What is not included
The PDF is text-based. If the email has an HTML version, it is reduced to plain text, so colors, images, tables, and layout are not kept. Attachments are not embedded; their file names are listed at the end of the PDF. Characters the PDF font cannot display, such as emoji and some non-Latin scripts, appear as question marks.
Tips for saving emails as evidence
Export the email as an .eml file from your mail program (usually via “Save as”, “Download message”, or by dragging the message to a folder). Keep the original .eml too, because it contains the complete technical headers that a PDF does not. If you need to keep attachments, save them separately alongside the PDF. To combine several emails and attachments into one file, use Merge PDF.
