Free Convert MBOX to PDF With Attachments

Need to open and convert an MBOX file to PDF? Our free online tool lets you read MBOX mailboxes and save any email as a PDF, right in your browser. MBOX is the mailbox format used by Gmail Takeout, Mozilla Thunderbird, Apple Mail, and other clients. A single MBOX file can hold hundreds or thousands of emails in one archive, along with their attachments, sender details, and formatting.

Open and Convert MBOX to PDF Without Installing Software

Drag and drop your .mbox file onto the converter. The tool reads the mailbox and lists every email inside it. Click any email to view it with its original formatting and attachments, then use the "Print / Save PDF" button to create a clean PDF copy of that message.

The entire process runs inside your web browser. There is nothing to download or install, and your mailbox never leaves your device, which makes it a safe choice for sensitive or confidential archives.

Frequently Asked Questions

Is this MBOX to PDF converter free?

Yes. You can open MBOX files and save emails as PDF for free, with no signup.

Do I need to upload my MBOX file?

No. The file is read locally in your browser and never leaves your device.

Can it open a Gmail Takeout file?

Yes. Google Takeout exports Gmail as a .mbox file, which this tool can open.

How large a file can it handle?

It reads the mailbox in small pieces, so most Takeout and Thunderbird files open fine, even large ones. Files over 2 GB are too big for the browser. If you hit that limit, export your Gmail in smaller files from Google Takeout by setting a smaller export size, then open one of those here.

Does it keep attachments?

Yes. When you open an email, its attachments are listed and can be downloaded individually or all at once.
