Frequently Asked Questions

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

MBOX is a standard format for storing collections 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 servers.

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 multiple emails into one PDF or split them into separate files?

Both options are supported. You can merge an entire mailbox into a single PDF document or generate one PDF per email, depending on your workflow.

Does the app preserve email metadata like sender, recipient, 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 data externally.

How does MBOX to PDF compare to printing emails manually?

Manual print-to-PDF requires opening each email individually in a mail client. MBOX to PDF automates the entire process with batch conversion, uniform formatting, and professional finishing options like watermarks and page numbers.

What page sizes and formatting options are available?

You can choose from standard page sizes (Letter, A4, A5) or set custom dimensions. Additional controls include margins, headers, footers, watermarks, confidential stamps, font selection, 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.
