Frequently Asked Questions

What is an MBOX file?

MBOX is a standard file format for storing email messages. It is used by many email clients including Mozilla Thunderbird, Apple Mail, and is the export format for Gmail via Google Takeout. Each MBOX file can contain multiple emails stored sequentially.

How do I export MBOX from Thunderbird?

In Thunderbird, you can use the ImportExportTools NG add-on to export folders as MBOX files. Alternatively, you can find your MBOX files directly in your Thunderbird profile folder under the Mail directory.

How do I get MBOX from Gmail?

Use Google Takeout (takeout.google.com) to export your Gmail data. Select Gmail, choose MBOX format, and download the archive. The resulting .mbox file can be uploaded directly to our converter.

Do I need to log in to convert MBOX files?

Yes, MBOX conversion requires a registered account. This is because MBOX files can contain many emails requiring significant processing power. Create a free account to get started.

What happens to email attachments?

Email attachments are processed the same way as regular email-to-PDF conversion. Office documents are converted to PDF, images and existing PDFs are included directly. All attachments are merged with the email body into a single PDF per email.

How many emails can an MBOX file contain?

We support MBOX files containing up to 500 emails for processing. If your MBOX contains more emails, consider splitting it using email client tools or processing in batches.

What can I do if my MBOX file is too large?

If your MBOX file is too large, consider compressing it through ZIP. This is really simple. Just go to your file library, right-mouse click on your file and select ‘compress in ZIP-file’. Your file size can be greatly reduced, and you can still use the ZIP file on PDFen

Can I merge all emails into one PDF?

Yes! Use our Merge MBOX to PDF option to combine all emails from your MBOX archive into a single PDF document. This is perfect for creating consolidated email reports or archives.

Why is it handy to convert my document to PDF?

Converting a file to PDF ensures your document stays consistent and accessible. PDFs lock in formatting, design, and structure, preventing layout shifts that can happen with editable file types. They’re compatible with virtually all devices and operating systems, making them ideal for professional documents, forms, reports, and presentations. PDFs are also easy to distribute; whether through email, downloads, cloud platforms, or QR-codes that let users open a file instantly on their phone.

Will documents lose quality when converted?

Our intelligent software minimizes quality loss when converting documents. As such, documents can be converted without having to worry about quality loss for a great number of times.

Will my document lay-out or format be changed if I convert it?

No; our intelligent PDF software recognizes document layouts and transforms them accurately onto a new file format. Was your lay-out or format not transformed accurately? Consider applying OCR, or applying different customization settings to convert it correctly.

Can I convert a document into PDF and convert it back into original format?

Yes! There are no limits to converting documents, and documents can safely and easily be converted back and forth. Conversion can be handy to edit a PDF document in Word, and later convert it back into an organized PDF format.

How can I merge PDF documents?

To merge PDF documents simply go to our converter, choose the file format you’re merging, and drag and drop the files you want to merge. Then you have the opportunity to edit some settings, press merge, and you’re done! You can download your merged file right away.

Can I customize my PDF documents while converting?

Yes, PDFengine offers various means of customizing your (PDF) documents. Consider adding a cover page, applying OCR, or using PDF/A as output.

Why is the text in my PDF not displayed correctly?

If the text is not copyable, clickable, or searchable, that means the text is not recognized within the PDF. Try uploading your document onto PDFen and applying OCR. OCR technology will make your text readable. In case it doesn’t work completely in one go: apply OCR a second time.
