Convert an HTML file to an Outlook .msg message while preserving the exact HTML markup and email metadata. The resulting .msg contains the uploaded HTML as the message body without any re‑rendering, so the visual layout you designed is kept intact. Works for single HTML files up to 10 MB; larger files or batch conversions require a paid account.

HTML markup retained in the message body

The uploaded HTML file becomes the exact body of the Outlook .msg, with every tag, style attribute, and layout element preserved. Because the converter does not re‑render the markup, tables, divs, CSS classes, and inline styles appear in the received email exactly as designed in the original file.

Metadata and header fields preserved

All standard email headers present in the source HTML – such as Subject, From, To, Cc, and custom X‑ headers – are copied into the .msg file unchanged. This ensures that when the message is opened in Outlook, the original addressing and subject line are displayed without alteration.

Embedded resources stay functional

Images referenced with data‑URI or local src attributes are embedded in the output .msg so they display directly in Outlook, and hyperlinks remain fully clickable. The conversion keeps the link targets intact, providing a seamless experience for recipients who need to follow URLs or view embedded pictures.
