Outlook has no direct Save as PDF button. The built-in route is File then Print then Microsoft Print to PDF fast for one email but it drops inline images, breaks complex HTML tables and ignores background colours. For better formatting, save the email as HTML first and open it in a browser before printing to PDF. For batch conversion of hundreds or thousands of emails from a PST file with full formatting preserved use Univik PST Converter. It reads PST files directly and outputs one PDF per email with attachments, images and folder structure intact.
Why Formatting Breaks in Outlook’s Native PDF Export
You print an email to PDF and the result looks nothing like what you saw on screen. The signature image is gone. The table is split awkwardly across two pages. The company letterhead background has disappeared. The fonts are different.
This is not a bug. It is how Outlook’s print function works.
When you print an email in Outlook, the application renders the email through its internal print engine rather than through the HTML rendering pipeline that displays it on screen. These two render paths produce different output. The print engine is designed to create clean, readable printed pages which means it strips or simplifies elements that do not translate well to paper: background colours, some image types, complex CSS and table cell backgrounds.
The result is a PDF that looks like a simplified printout rather than the actual email.
The new Outlook has fewer options
Microsoft is migrating users from the classic Outlook desktop application to the new web-based Outlook. The new version has significantly fewer PDF export options than the classic app. If you cannot find the Print to PDF option, check whether you are running classic Outlook desktop (recommended for these methods) or the new Outlook. Classic Outlook can still be installed alongside the new version on Windows 11.
Method 1: Print to PDF Built-In, Single Emails
This is the fastest method and works on Outlook 2010 or later on Windows 10 or later. It takes about 15 seconds per email.
Open the email you want to export. Double-click it to open it in its own window rather than reading it in the preview pane. The preview pane print output is lower quality than printing from the full window.
Go to File then Print (or press Ctrl+P). In the printer dropdown, select Microsoft Print to PDF. If this option is not visible, it means the Microsoft Print to PDF printer driver is not installed. Go to Windows Settings then Devices then Printers and Scanners and add it.
Click Print. Windows will prompt you for a save location and filename. The default filename is the email subject line. Choose your folder and click Save. The PDF is created immediately no actual printing happens.
To export multiple selected emails into a single PDF, select them in the folder list using Ctrl+click (individual selection) or Shift+click (range), then press Ctrl+P. All selected emails are combined into one PDF file in the order they appear in the folder.
What this method loses
Background colours on table cells, background images in email signatures, some inline images depending on email source and HTML elements that rely on external CSS. If your emails use a branded template with coloured headers and footers, this method will produce a plain black-and-white output. For better results, use Method 2.
Method 2: Save as HTML Then Convert Better Formatting Preservation
This method routes the email through a browser’s print engine rather than Outlook’s print engine. Browsers render HTML email correctly they are built for it. The result is a PDF that far more closely resembles the email as it appeared on screen.
Open the email in its own window. Go to File then Save As. In the Save As dialog, change the Save as type dropdown to HTML (*.htm, *.html). Name the file and choose a folder a new subfolder is created alongside the HTML file containing all images and attachments referenced in the email.
Open the HTML file in Chrome, Edge or Firefox. The email renders in the browser with full formatting colours, images, tables and signature graphics all appear correctly. Check it looks right before proceeding.
Press Ctrl+P in the browser. Select Save as PDF as the destination (not a physical printer). Set paper size and margins as needed for email archives, A4 with minimal margins gives the most readable output. Click Save and choose the output location.
This method works on any version of Outlook, including older versions that predate the Microsoft Print to PDF driver. It also works if you are exporting on a Mac.
The limitation is scale. Saving each email as HTML, opening it in a browser and printing to PDF is practical for 5 to 10 emails. For 500, it takes hours. For a full mailbox export, it is not viable. That is what Method 3 solves.
Method 3: Batch Export via PST Converter Best Results at Scale
Your Outlook mailbox is stored as a PST file. Every email, every folder, every attachment lives inside that one file. A PST converter reads this file directly and converts each email to PDF bypassing Outlook’s print engine entirely and using its own rendering pipeline that preserves HTML email formatting correctly.
Univik PST Converter handles this on Windows without requiring Outlook to be installed. Load the PST file, select the folders you want to convert, choose PDF as the output format and run the conversion. Each email is saved as an individual PDF named by subject and date, organised in the same folder hierarchy as the original mailbox.
What Univik PST Converter Preserves
- Inline images embedded in email body
- Signature images and logos
- Background colours on table cells
- HTML table structure and cell widths
- Hyperlinks (clickable in the PDF)
- Email headers (From, To, CC, Date, Subject)
- Original folder hierarchy in output naming
- Attachments (embedded or saved separately)
What It Does That Outlook Cannot
- Converts thousands of emails in one batch run
- Works without Outlook installed
- Reads PST files directly no export step required
- Produces one PDF per email automatically
- Also converts EML and MSG files to PDF
- Generates a conversion report for compliance records
- Filters by date range, folder or sender before converting
- 100% offline no data uploaded anywhere

When You Need Batch PDF Export
Method 1 and Method 2 are fine for occasional one-off exports. They stop being practical the moment you have more than about 20 emails to convert. Here are the situations where batch PDF export becomes necessary.
Legal Discovery
A litigation hold requires producing specific email conversations in PDF. Dozens or hundreds of emails need to be exported quickly in a format opposing counsel and courts accept.
Compliance Archiving
Regulated industries (healthcare, finance, legal) require email records in a non-editable format for defined retention periods. PDF is the standard court-accepted format.
Employee Offboarding
A departing employee’s mailbox needs to be archived as PDF before the account is deleted. A full PST export converted to PDFs preserves the record permanently.
Platform Migration
Moving from Outlook to Google Workspace and want a PDF archive of historical email before the PST files are decommissioned. One batch run covers the entire mailbox.
For the migration use case specifically, you may want to read our Outlook to Google Workspace migration guide which covers the full workflow including what to do with PST archives before you decommission them.
Frequently Asked Questions
Why does my PDF look different from the email I see in Outlook?
Outlook’s print engine renders emails differently from its display engine. Background colours, some images and complex HTML elements that display correctly on screen are stripped or simplified when sent through the print pipeline. Using Method 2 (HTML via browser) or Univik PST Converter routes the email through a different rendering path that produces output much closer to what you see on screen.
Can I export Outlook emails to PDF with attachments included?
Not natively through Outlook’s print method. Attachments are separate files and the Print to PDF function only captures the email body. Univik PST Converter offers an option to embed attachments in the PDF or save them alongside it as separate files, depending on your use case.
How do I batch convert hundreds of Outlook emails to PDF?
Export your mailbox as a PST file first (File then Open and Export then Import/Export then Export to a File then Outlook Data File). Then load that PST file into Univik PST Converter, select the folders you want to convert, choose PDF output and run the batch. Each email is saved as a separate PDF named by subject and date.
Does the Microsoft Print to PDF option work on all Outlook versions?
Microsoft Print to PDF requires Windows 10 or later and Outlook 2010 or later. On older systems use Method 2 save the email as HTML, open in a browser and print from there. This produces better formatting output anyway and works on any version of Outlook.
I don’t have Outlook installed. Can I still convert a PST file to PDF?
Yes. Univik PST Converter reads PST files directly without Outlook. This is useful for converting archives on a dedicated conversion machine, a forensic workstation or any Windows machine that has never had Outlook installed. See our PST repair guide if the PST file is damaged before conversion.
Will the PDF preserve the email timestamp and header information?
Yes with all three methods. The From, To, CC, Subject and Date fields from the email header appear in the PDF output. Univik PST Converter also includes the received timestamp and folder path in the output, which is particularly useful for legal and compliance purposes where provenance matters.
Conclusion
Verified against Outlook 2019 and 2021 on Windows 11. HTML browser method tested in Chrome 124 and Edge 124. PST conversion examples tested with Univik PST Converter current release.
Outlook’s Print to PDF is useful but imperfect it misses signatures, drops table backgrounds and cannot handle more than a few emails at a time without becoming tedious. The HTML browser method fixes the formatting problem for small batches. For anything larger, a PST converter is the only practical path.
The specific formatting element you are most likely to lose with native methods is the signature image. If that matters for your use case, skip to Method 2 or Method 3 directly.
What is your use case for the PDF export compliance archiving, legal discovery or something else? The answer usually determines which method is worth the setup time.
