Features

Everything a serious archive demands.

Purpose-built for legal, compliance, and archival work — with the formatting controls professional output actually requires.

Streaming engine

Progressive loading processes multi-gigabyte Gmail Takeout archives without maxing out RAM.

Watermarks & stamps

Custom text, "Confidential" stamps, and legal disclaimers applied uniformly across every page.

Headers & footers

Page numbers, document titles, and dates — essential for court filings and audit trails.

Combined or split

Merge an entire mailbox into one paginated PDF, or export one file per email.

Attachment extraction

Organizes attachments into dedicated folders alongside the generated PDFs.

Content cleanup

Strip quoted replies, force white backgrounds, or render everything black & white.

Flexible page layouts

Letter, A4, A5, or custom dimensions with precise margin control for print or binding.

Real-time preview

See the final output before exporting. Tune margins, fonts, and stamps until it's exactly right.

100% on your Mac

Every conversion is local. No uploads, no accounts, no telemetry — ever. Your email stays yours.

Screens

A focused workspace for batch work.

Three panels, one job. Pick what to export on the left, preview live in the center, tune formatting on the right.

Workflow

MBOX to PDF in four steps.

No command line. No scripting. No printing emails one at a time like it's 2005.

01

Import your MBOX archive.

Drag one file or a folder of them. Gmail Takeout, Thunderbird, Apple Mail, ProtonMail, Fastmail, Dovecot, Postfix — if it exports standard MBOX, it works.

02

Choose how the output should read.

One continuous PDF with sequential page numbers for legal submissions, or one PDF per email for a browsable personal archive. Both can run in the same batch.

03

Shape the formatting, live.

Pick page size, margins, headers, footers, watermarks, and stamps. Toggle content cleanup. Preview every change in real time before you commit to a batch run.

04

Export — attachments and all.

Produces compliance-ready PDFs in minutes, with attachments extracted into a dedicated folder alongside them if you want them separated.

Who it's for

Built for archives that matter.

From legal discovery to personal preservation, MBOX to PDF handles the work that used to take a week.

Legal

Discovery & eDiscovery

Personal

Back up years of Gmail Takeout, Thunderbird, or Apple Mail into an archive you can browse in Finder — no mail client required, ever.

FAQ

Questions, answered.

What is an MBOX file and where does it come from? +

MBOX is a standard format that stores a collection of email messages in a single file. You get MBOX files from Gmail via Google Takeout, from Thunderbird profiles, from Apple Mail exports, and from many other email clients and mail servers like Dovecot or Postfix.

Can MBOX to PDF handle very large mailbox files? +

Yes. The app uses a streaming engine with progressive loading, so it can process multi-gigabyte archives without running out of memory.

Can I combine emails into one PDF or split them? +

Both. You can merge an entire mailbox into a single continuous PDF with sequential page numbers, or generate one PDF per email for a browsable archive.

Does the app preserve email metadata like sender and date? +

Yes. Sender, recipient, CC, BCC, subject, and timestamp fields are rendered in the PDF output. You can customize which fields appear and how they are styled.

Is my email data sent to any server during conversion? +

No. All processing happens locally on your Mac. The app does not require an internet connection and never transmits your email content externally.

Does MBOX to PDF support watermarks and confidential stamps? +

Yes. Add custom watermarks, confidential stamps, legal disclaimers, page numbers, headers, and footers that apply uniformly across the entire batch — ideal for legal and compliance workflows.

What page sizes and formatting options are available? +

Letter, A4, A5, or custom dimensions. Additional controls include margins, headers, footers, watermarks, confidential stamps, font selection, remove-quoted-replies, force white backgrounds, and black-and-white mode.

Does MBOX to PDF extract email attachments? +

Yes. Attachments can be automatically extracted and organized into dedicated folders alongside your converted PDFs.

How much does MBOX to PDF cost? +

Free to download from the Mac App Store with a one-time premium upgrade to unlock unlimited conversions. No subscriptions.

Which macOS version is required? +

macOS 13.5 or later. Runs natively on Apple Silicon and Intel Macs.
