MBOX to PDF conversion plays a vital role across industries – due to the significance of PDF in e-discovery, forensics, and printing needs. Here we have listed exact step-by-step methods for your needs.

MBOX V/S PDF – Which is Better? 

Both .mbox and .pdf are widely used file formats serving different purposes. While MBOX files are generally associated with email clients such as Thunderbird, Apple Mail, Google Takeout, etc., for local email storage in bulk. PDF (portable document format) was created by Adobe for more portable access to data. To take advantage of both worlds, users convert the MBOX File to PDF.

Here are the core differences between them:

MBOX PDF
Restorable Email Format Document Format
Only Text-Based Has Visual Formatting
Needs a dedicated email client or viewer tool Can be opened anywhere (browser supported)
Emails can be encrypted Data can be password-protected
Low searchability Easy Search

Oftentimes, law firms, businesses, and government agencies need to save MBOX as PDF for reasons such as audit, documentation, and compliance. It lets you:

  • Read, access, and share MBOX across multiple devices
  • Present MBOX archives as legal evidence in PDF format
  • Long-term document archival with reduced corruption risk

  • Print archived MBOX with formatting, logos, signature & attachments

Export MBOX to PDF Format with Attachments Using Thunderbird

To convert an MBOX file to PDF format, we have to take the help of an MBOX file-supported application. We will use Thunderbird, which is free for all and open source, and it supports exporting emails in the PDF format. This method is divided into two parts; both are explained below with all details and information:

Stage 1: Import MBOX Files to Thunderbird

Firstly, we have to upload your orphaned MBOX files into a Thunderbird account to convert them into PDF format. Steps are given below:

  1. Open Thunderbird.
  2. Go to “Tools” >> “ImportExportTools NG” >> “Import MBOX File”.

    import data

  3. Now, you can choose the import way as per your need and click “OK”.
  4. Find the orphan MBOX file to upload it, and choose the “Open” button.

    upload file

  5. Restart your Thunderbird and check the MBOX file in your Thunderbird account.

Stage 2: Convert MBOX File to PDF Format

  1. Find and select the imported MBOX in TB.
  2. Choose the “Tools” >> “ImportExportTools”.
  3. Choose the “Export All Messages in the Folder” option.
  4. After that, select the “PDF Format” from the list.

  5. And your MBOX file will be converted into PDF format.

After analyzing the manual process to export MBOX to PDF, let’s come to the setbacks of this manual method, which is important to know before proceeding with the process.

Convert MBOX File to PDF on Mac Devices

You can save MBOX to PDF on Mac OS without any additional installation or extension setup for free. This is due to the Mail App’s ability to support MBOX format and export MBOX emails to PDF. Here are the steps to follow:

  1. Open Mail App on your Mac.
  2. Select File and click Import Mailboxes.
  3. Choose the Files in MBOX format option.
  4. Select the MBOX files stored on your PC.
  5. Go to that new MBOX folder in Apple Mail.
  6. Open the MBOX email to be saved as a PDF.
  7. Click on File >> Export as PDF option.

This method is functional for the selective extraction of emails or in case you have a limited number of emails in MBOX format, as Apple Mail does not support bulk “Export as PDF”.

Setbacks of Manual Methods to Convert MBOX to PDF

  • Attachments will be lost whether using Apple Mail or Thunderbird to convert MBOX to PDF.
  • With the manual approach, you need more space on your PC as they involve first creating an MBOX copy inside an email client.
  • Certain MBOX architecture types are not supported, making the process unreliable.
  • Will not work even if your old MBOX files have even minor corruptions.
  • You can’t convert an MBOX file to PDF format in bulk at once.
  • Thunderbird installation is important on your machine.
  • This manual method has a risk of losing emails and the folder hierarchy.

Although there are setbacks, but they can be avoided using the reliable method discussed below.
