How to Convert Outlook Emails to Non-Searchable PDF

You need to share email records with an external party but do not want the text to be copied, indexed by search engines, or processed by text-mining tools. A standard PDF stores text as selectable characters — anyone can copy-paste the content or run a full-text search. A non-searchable PDF renders each page as an image, so the text is visible but cannot be selected, copied, or found by search tools. Total Outlook Converter reads Outlook PST files and converts emails to non-searchable PDF in batch — one email per file or all emails merged into a single document.

Searchable vs Non-Searchable PDF: What Is the Difference?

Searchable (standard) PDF

Text is stored as Unicode characters. You can select text, copy it to the clipboard, use Ctrl+F to search within the document, and full-text indexing tools (Google Desktop, Windows Search, e-discovery software) can read every word. This is the default output of most PDF creators.

Risk: The recipient can copy email content into other documents, forward text extracts, or run automated data extraction on hundreds of files at once.

Non-searchable (image) PDF

Each page is rendered as a raster image (like a scanned document). The text is visually readable but cannot be selected, copied, or found by search. PDF viewers show the content as a flat image layer with no underlying character data.

Benefit: The content is protected from casual copying, text mining, and automated indexing. The email is readable by a human but not by a machine.

Why Convert Emails to Non-Searchable PDF?

  • Prevent unauthorized copying — sensitive internal communications, HR records, or legal correspondence cannot be copy-pasted into external documents.
  • Block text mining and indexing — non-searchable PDFs are invisible to full-text search engines, e-discovery crawlers, and data-scraping tools.
  • Comply with corporate security policies — some organizations require email exports to be in non-searchable format to limit the risk of data leaks after sharing.
  • Protect email archives from tampering — an image-based PDF cannot be edited in a text editor. The content stays as it was at the moment of conversion.
  • Provide read-only evidence — when submitting emails as evidence or audit documentation, a non-searchable PDF shows the content without allowing selective extraction.

How to Convert Outlook Emails to Non-Searchable PDF — Step by Step

Step 1. Open the PST File

Launch Total Outlook Converter. The left panel shows Outlook folders from your default PST file: Inbox, Sent Items, Drafts, Deleted Items, and any custom folders. To open a different PST file, use File → Open PST.

Step 2. Select Emails

Click on a folder (e.g., Inbox). The email list shows Sender, Subject, Date, and a preview of the message body. Tick the emails you want to convert. Click Check All to select every message in the folder.

Step 3. Choose PDF Format

Click the PDF button on the toolbar. The conversion wizard opens with multiple tabs:

  • Destination — choose the output folder. Select "Combine all emails into one PDF" or "One PDF per email."
  • Fields — select which email fields to include: From, To, CC, Date, Subject, Body, Attachments.
  • Appearance — set font, font size, and page layout.
  • Header / Footer — add date, page number, or custom text.

Step 4. Enable Non-Searchable Mode

Go to the Document → Properties tab. Check the Non-searchable document checkbox. This tells the converter to render each page as an image instead of storing selectable text. You can also fill in Author, Creator, Keywords, Subject, and Title fields for the PDF metadata.

Step 5. Click Start

Press Start. Total Outlook Converter reads each email from the PST file, renders it as an image-based PDF page, and writes the output. A progress bar shows the status. The result is a set of non-searchable PDF files — readable by any PDF viewer but resistant to text extraction.

Command-Line Conversion

Total Outlook Converter includes a command-line interface for automated processing:

OutlookConverter.exe "C:\Mail\archive.pst" -cPDF -dNonSearchable -o "C:\Output\"

Parameters: PST file path, -cPDF sets the target format, -dNonSearchable enables image-based rendering, -o specifies the output folder. Save this in a .bat file and schedule it with Windows Task Scheduler. Automate monthly email archival to non-searchable PDF without opening the GUI.

Why Choose Total Outlook Converter?

Reads PST files directly

Total Outlook Converter opens PST files without requiring Microsoft Outlook to be running. Point it at any PST file — active or archived — and browse the folder structure, preview messages, and select emails for conversion.

Batch conversion of entire folders

Select 10 emails or 10,000. The converter processes the entire batch with the same settings. No need to open each email individually. Combine all messages into one PDF or create separate files — your choice.

Full control over email fields

Choose exactly which fields appear in the output: From, To, CC, BCC, Date, Subject, Body, and Attachments. Hide fields you do not want in the exported document. Set custom headers and footers with page numbers, dates, or company branding.

Attachment handling

Email attachments can be embedded into the PDF, saved as separate files alongside the PDF, or excluded entirely. Inline images are rendered as part of the email body.

More than just PDF

Total Outlook Converter also exports emails to DOC, HTML, XHTML, TXT, TIFF, JPEG, EML, and MSG formats. Switch the target format with one click. The non-searchable option is available for PDF output.

When Do You Need Non-Searchable Email PDFs?

  • Legal discovery — a law firm produces email records for opposing counsel. Non-searchable PDFs prevent automated text extraction and limit the ability to repurpose the content.
  • HR investigations — internal emails related to an employee matter are exported for review by an outside investigator. Non-searchable format reduces the risk of content being forwarded or quoted out of context.
  • Financial audits — an auditor requests email evidence. The company provides non-searchable PDFs that show the communication but cannot be indexed or text-mined alongside other data sets.
  • Government FOIA responses — agencies redact and release emails in non-searchable PDF to prevent automated extraction of unredacted content from surrounding text.
  • Intellectual property protection — R&D emails shared with a partner under NDA are exported as non-searchable PDFs so the technical content is viewable but cannot be easily copied into competing documentation.

Rated 4.7/5 based on customer reviews
5 Star

"External auditors request email evidence quarterly. Our policy requires all exports to be non-searchable to prevent the content from being indexed into third-party systems. Total Outlook Converter handles the entire Inbox — 2,000+ emails — in one batch. The non-searchable checkbox is all it takes. Exactly what we needed."

5 Star Richard Donovan Compliance Manager, Financial Services

"We produce email records for discovery. Opposing counsel gets non-searchable PDFs so they cannot run automated text extraction across thousands of pages. Total Outlook Converter merges emails per custodian into one file, adds page numbers in the footer, and marks them non-searchable. Saves our litigation support team hours per case."

5 Star Catherine Alvarez Paralegal, Corporate Law Firm

"When we share project emails with subcontractors, non-searchable PDF is mandatory per our IP policy. The command-line mode lets me script the conversion for specific PST folders on a schedule. File sizes are larger than regular PDFs, but the trade-off is worth it for the protection."

4 Star Niels Brouwer IT Security Officer, Engineering Firm

In the conversion wizard, go to Document, then Properties. Check the Non-searchable document checkbox. This single setting converts the entire output to image-based PDF.
Yes. On the Destination tab, select the option to combine all selected emails into one PDF file. The non-searchable setting applies to the combined document. Each email starts on a new page.
