Format Details
MSG
MSG is Microsoft Outlook's proprietary format for saving individual email messages, meeting requests, contacts, and tasks as standalone files. Unlike the standard EML format, MSG files use Microsoft's Compound Document File Format and require Outlook or a compatibility library to fully decode. MSG files preserve all rich formatting, embedded images, attachments, and complete email metadata, and are widely used in enterprise email archiving and legal discovery.
documentEPUB
EPUB (Electronic Publication) is the most widely adopted open standard ebook format, developed by the IDPF and now maintained by the W3C. It packages HTML, CSS, fonts, and images into a single ZIP-based container, allowing text to reflow and adapt to different screen sizes, font sizes, and user preferences. EPUB is supported by virtually all e-readers except Amazon Kindle devices, and is the preferred format for accessible, standards-compliant digital books.
ebookConverting MSG to EPUB: what actually changes
MSG to EPUB is one of the conversions this site performs, but the two formats are not interchangeable containers. Here is what the file keeps, what it loses, and how to get a result you can use.
What .MSG and .EPUB each hold
.MSG is a document format built for reading, printing or circulating a document, storing text, layout, fonts and images. .EPUB is a ebook format built for reading a book on an e-reader or in an app, storing chapters, images and reading order. Converting between them is a decision about which of those two jobs the result needs to do.
What changes when categories differ
This conversion translates text, layout, fonts and images into chapters, images and reading order so the result can be used for reading a book on an e-reader or in an app. The meaning of the file is preserved; the way it is stored, and some format-specific detail, changes with the target.
When this conversion is the right one
Reach for .EPUB when you need a file for reading a book on an e-reader or in an app, starting from reading, printing or circulating a document. If that is not what you are after, check what else .MSG converts to before committing to this target.
Tips for a clean MSG to EPUB conversion
Start from the original file
Convert the .MSG you started with, not an earlier .EPUB output. Every extra round trip costs quality and can accumulate formatting drift.
Check the real type, not the extension
Application/vnd.ms-outlook becomes application/epub+zip. If a file was renamed rather than converted, it will fail to open — rename it back to its true extension before uploading and the conversion will recognise it.
Long documents convert as pages
Page-based output renders one page at a time. Split very large .MSG files first if you only need a specific section — it is faster and keeps the result easy to work with.
Limits worth knowing
Uploads are capped per file (30 MB, or 100 MB for video) and processed temporarily — nothing is kept as a permanent copy. For huge document files, split or compress the source first.
