How to convert MBOX to PDF

  1. 1

    Choose your MBOX file

    Click the upload area or drag files onto it. Nothing is uploaded — files are opened locally.

  2. 2

    Adjust the settings

    Pick page size, then press the convert button.

  3. 3

    Download the result

    Save each file individually or everything at once as a ZIP.

Save emails from Gmail Takeout, Thunderbird and Apple Mail as PDFs for legal records, invoices, HR files or printing. Each message gets a header block with From, To, Cc, Date and Subject followed by the body text, and attachments are listed by name. Every message in the mailbox goes into one PDF, starting on a new page.

What is MBOX?

MBOX stores a whole mailbox — thousands of emails — in one file. Google Takeout, Thunderbird and Apple Mail exports all use it.

What is PDF?

PDF (Portable Document Format) preserves a document’s layout on every device and operating system, which makes it the standard for sharing, printing and archiving.

Is it private?

Yes. Unlike upload-based converters, ZapMorph processes files inside your browser tab, so the file stays on your device. It is never transmitted, stored or logged — close the tab and it’s gone.

Frequently asked questions

Is the mbox to pdf converter free?

Yes. Convert 1 file a day without an account, or 5 files a day with a free account. Pro removes all daily limits.

Are my files uploaded to a server?

No. The conversion runs entirely in your browser, so your files never leave your device. We only count how many files you convert — never their names or contents.

What is the maximum file size?

Up to 25 MB per file without an account, 50 MB with a free account, and 1 GB on Pro. Very large files also depend on your device’s memory.

Can I convert multiple MBOX files at once?

MBOX to PDF Converter works on one file at a time and can produce many output files, which you can download together as a ZIP.

Does it work on Mac, Windows, iPhone and Android?

Yes. It works in any modern browser — Chrome, Edge, Firefox and Safari — on desktop and mobile, with nothing to install.
