Convert Outlook to HTML — Export PST Emails as HTML Files in Batch

• Maintains the original Outlook folder structure in the output
• Works 100% offline — no email data leaves your machine
• Includes a 30-day free trial with full functionality

PST vs HTML: Why Convert?

PST (Personal Storage Table) is Microsoft Outlook's proprietary archive format. It bundles emails, contacts, calendar entries, and attachments into a single binary file. Opening a PST requires Outlook or a specialized viewer — you can't browse individual messages in a file manager, web browser, or any non-Microsoft application.

HTML is the universal language of the web. Every device with a browser can display HTML files. Converting Outlook emails to HTML produces standalone web pages that preserve the original formatting — fonts, colors, tables, and inline images — while making the content accessible to anyone, on any platform, without Outlook.

Common reasons to convert Outlook to HTML include publishing email newsletters on a website, creating browser-searchable archives, migrating email content to a CMS, and sharing formatted correspondence with non-Outlook users.

Supported Output Formats

Total Outlook Converter handles more than just HTML. You can convert PST emails to multiple formats from a single tool:

Format	Use Case
HTML	Web publishing, browser-based archives, CMS import
PDF	Legal discovery, fixed-layout archiving, sharing
DOC / DOCX	Editing email content in Word
TXT	Plain-text extraction, data analysis
TIFF	Court filings, document imaging
JPEG	Quick image snapshots of emails
EML	Universal email format for other clients
MSG	Individual Outlook message files

How to Convert Outlook Emails to HTML

• Step 1. Launch Total Outlook Converter. The left panel displays a folder tree. Select the PST file you want to convert, or point to the default Outlook data file.
• Step 2. The email list shows all messages in the selected PST folder with sender, subject, and date. Check individual emails or click Check All to select the entire folder.
• Step 3. Click HTML in the toolbar to set HTML as the output format.
• Step 4. In the conversion wizard, choose the destination folder. Select which email headers to include (From, To, Subject, Date, CC) and set the HTML encoding (UTF-8 recommended).
• Step 5. Choose how to handle attachments: save them as separate files in the same folder, or skip them. Configure the output file naming pattern (by sender, date, or subject).
• Step 6. Press Start. Each email becomes an individual HTML file. The original PST file remains untouched.

The converter preserves the Outlook folder hierarchy in the output directory — Inbox, Sent Items, and custom folders each get their own subfolder, making it easy to navigate the exported HTML archive.

Command-Line Conversion

Total Outlook Converter includes a command-line interface for scripted and automated workflows. Convert a PST file to HTML:

OutlookConverter.exe C:\Data\archive.pst C:\Output\ -cHTML

Convert with specific folder and attachment settings:

OutlookConverter.exe C:\Data\archive.pst C:\Output\ -cHTML -FolderTree -SaveAttachments

Schedule this as a Windows Task or embed it in a .bat script for automated PST-to-HTML exports — useful for recurring backups, compliance workflows, and web publishing pipelines.

Why Use Total Outlook Converter?

Full HTML formatting

Converted HTML files preserve the original email appearance: fonts, colors, tables, and inline images render exactly as they did in Outlook. Each email becomes a self-contained web page.

Batch processing

Convert an entire PST archive in one run. Select a single folder or the whole mailbox — the converter processes thousands of emails sequentially, creating one HTML file per message.

Folder structure preserved

The converter recreates Outlook's folder hierarchy on disk. Inbox emails go to an Inbox subfolder, Sent Items to Sent Items, and so on. Custom folders are preserved as well.

Custom file naming

Name output files by sender, subject, date, or a combination. This produces an organized HTML archive that is easy to search and navigate without any database.

Header control

Choose which email headers appear in the HTML output. Include From, To, CC, Subject, and Date — or hide headers entirely for clean content-only export.

No cloud uploads

All conversion runs on your local PC. Sensitive corporate email, legal correspondence, HR records — nothing leaves your machine. No internet connection required.

Total Outlook Converter Customer Reviews 2026

Rate ItRated 4.7/5 based on customer reviews

"We exported 8,000 Outlook emails to HTML for our company intranet. The folder structure was preserved perfectly, so we could mirror the original mailbox layout on the web server. Inline images and formatting came through without any manual cleanup. The batch mode saved us weeks of work."

Margaret Holloway Knowledge Management Specialist

"Used this to create a browser-searchable archive of our executive correspondence before decommissioning an old Exchange server. The command-line mode let us automate the nightly PST export. Every email is now an HTML file indexed by Windows Search. Simple and reliable."

David Kessler IT Systems Administrator

"Good tool for converting PST emails to HTML for our regulatory archive. The header options let us include exactly the fields auditors need. Attachments are saved alongside each HTML file. Would like built-in timestamp watermarks, but the current header customization covers our requirements."
