MSG vs PDF: What Is the Difference?

MSG is the native format of Microsoft Outlook. Each MSG file contains a single email message: sender, recipients, subject, date, body (plain text or HTML), embedded images, and file attachments. MSG uses Microsoft's Compound File Binary Format (CFBF). Opening an MSG file requires Outlook, or a third-party MSG viewer — it cannot be read in a standard text editor or web browser.

PDF (Portable Document Format) is the universal standard for fixed-layout documents. A PDF file looks the same on every screen, every printer, and every operating system. PDFs can be read by hundreds of free viewers (Adobe Reader, Foxit, browser built-in readers). They support text search, encryption, digital signatures, and PDF/A archival compliance.

Feature	MSG	PDF
Creator	Microsoft Outlook	Adobe / ISO 32000
Viewer required	Outlook or MSG viewer	Any PDF reader, web browser
Content	Email message + attachments	Fixed-layout document
Editable	Yes (in Outlook)	Read-only by default
Text search	Requires Outlook indexing	Built-in full-text search
Digital signatures	S/MIME (email-level)	PFX/X.509 (document-level)
Archival standard	None	PDF/A (ISO 19005)

Why Convert MSG to PDF?

Universal access without Outlook — PDF files open on any device, any operating system, and any browser. Recipients do not need Outlook or any email client to read the message.
Legal and compliance archiving — regulations like SEC Rule 17a-4, HIPAA, and Sarbanes-Oxley require email retention in tamper-resistant formats. PDF and PDF/A satisfy these requirements.
Bates stamping for litigation — legal professionals need Bates numbers on every page. Total Mail Converter adds customizable Bates stamps during conversion — no separate tool required.
Digital signatures — sign converted PDFs with a PFX certificate to prove document authenticity. Both PDF and PDF/A formats support document-level signatures.
Attachment handling — embed attachments as clickable links inside the PDF, append them as additional pages (Pro version), or save them to a separate folder.

How to Convert MSG to PDF — Step by Step

Step 1. Open the MSG Folder

Launch Total Mail Converter. The folder tree on the left shows your local drives and network folders. Navigate to the directory containing your MSG files. The file list displays each email with its sender, subject, date, and file size.

Step 2. Select MSG Files

Tick individual files or click Check All to select the entire folder. Total Mail Converter handles batch conversion — one file or ten thousand in the same run.

Step 3. Choose PDF Format

Click the PDF button on the toolbar. The settings wizard opens with all PDF output options.

Step 4. Configure PDF Settings

Set the output folder and file naming pattern. Configure the following:

PDF type — standard PDF, searchable PDF, non-searchable (image-based) PDF, or PDF/A for long-term archival
Attachments — embed as clickable links, save to a subfolder, or skip
Bates stamps — add customizable Bates numbers with configurable font, size, and position
Digital signature — sign PDFs with a PFX certificate file
Page numbers — sequential across all files or restart per folder
Headers and footers — add custom text, date, filename, or page count
Security — set password protection and user permissions (allow/forbid printing, editing, copying)

Step 5. Convert

Click Start. Each MSG file is rendered as a PDF document: the email header (From, To, Subject, Date) appears at the top, followed by the message body with full HTML formatting, images, and links. The conversion log shows the status of every file.
