Offline .mbox archiving for desktop, web, and automation.

Archive old email as clean, organized PDFs.

MailboxPDF opens saved mailbox files, especially standard .mbox archives, and turns them into PDFs that are easier to file, preserve, print, and revisit over time. The same conversion functionality is available on Windows, macOS, Linux, and in your browser.

  • Fully offline
  • Translated interface
  • Same functionality on desktop and web

Start with the guide that matches where your mail came from.

These are the two main walkthroughs for people bringing real mailbox exports into MailboxPDF. Choose Gmail if your archive came from Google Takeout, or Thunderbird if it came from a local mail store.

Gmail guide

Export Gmail to PDF

Use this if your mail starts in Gmail. The guide shows how to label only the mail you want, export just that label through Google Takeout, and turn the resulting .mbox into a PDF archive.

  • Create one Gmail label just for the export.
  • Use Google Takeout to export that label instead of all mail.
  • Open the downloaded .mbox in MailboxPDF and save the PDF shape you need.
Thunderbird guide

Export Thunderbird to PDF

Use this if your mail lives in Thunderbird. The guide shows how to export one folder or a whole folder tree to .mbox with ImportExportTools NG before turning it into a PDF archive.

  • Choose a single folder, several folders, or a full folder tree.
  • Export to .mbox so the mailbox stays reusable.
  • Open the export in MailboxPDF and choose one PDF or a split archive set.

Bring an .mbox archive

MailboxPDF is built for saved mailbox exports, especially standard .mbox files.

Pick the format you need

Save one PDF for everything, one per email, or one per conversation.

Use it wherever you work

Native apps for Windows, macOS, and Linux, plus a browser version with the same functionality. A CLI tool is also available for power users and automation.

Made for long-term archiving first.

Whether you are keeping personal records, preserving a project history, or preparing a handoff, the goal is the same: turn a raw .mbox export into documents that are easier to file and keep.

Preserve years of email

Turn an old mailbox export into a durable PDF archive that is easier to store with the rest of your records.

File archives in a cleaner shape

Keep one PDF for the whole archive or split it into conversation-sized documents that are easier to name, sort, and retain.

Stay fully offline

Your mailbox stays on your own device. You do not need to upload the .mbox file anywhere else before turning it into a PDF.

Use the same functionality everywhere

Use the native app on Windows, macOS, or Linux, open the browser version, or reach for the CLI when you want scripting and automation.

Three steps from .mbox export to finished PDF.

The browser app keeps the flow simple so you can get from a saved archive to a usable document without learning a technical workflow first.

1

Open your .mbox file

Choose a saved mailbox archive from your device or drag it into the window.

2

Choose how it should be grouped

Keep everything together, save one PDF per message, or split the archive into conversation-sized pieces.

3

Preview, then download

Check the result before saving so the export feels predictable instead of surprising.

Choose the desktop app or the web app and turn a saved .mbox archive into something easier to file.

Use the same conversion workflow in your browser or download the latest desktop app when you want a local native tool.
