How to Convert Email Files to PDF

1. Add your email files

Drag your email files into the window, or click Add Files. Whole folders work too. Point the app at an export folder and it pulls every message inside.

2. Choose PDF output

Set the output to PDF, then pick one file per message or a single combined file. Switch Include images on to keep inline pictures in the page.

3. Start the batch

Click Start. Container files like PST and MBOX unfold on their own. Every folder and message drops into the queue, with no manual picking unless you want it.

Why SoftOrbits Email to PDF Converter

Why a desktop tool earns its place

Correspondence piles up in shapes that fight each other and outlive the programs that wrote them. One local converter does the jobs those programs no longer can:

Nothing quietly goes missing. Some apps save one at a time, and a few heavy exporters silently drop items on crowded mailbox. This writes every item you picked, so a disclosure set or an audit pack has no holes you only notice months later.
Confidential correspondence stays off the web. A browser uploader hands privileged material to a server you do not control, with retention and breach exposure you cannot answer for. Legal, HR, and finance keep this work on a desktop they own.
Open old mailboxes after the program is gone. An inherited 6 GB mailbox from a former colleague, or a backup with dozens of subfolders, turns into PDF with nothing to reinstall and no old login to recover first.
A document anyone can open. The result drops into a case record, a ticket, or a shared drive and opens on any device, with no email program and no proprietary viewer in the way.

What the converter does

Five mail formats, one reader

Reads single .eml (RFC 822) and .msg messages, Outlook .pst and .ost archives, and .mbox from Thunderbird or Apple Mail. The right engine for each format is built in, so you do not match a tool to a file.

Containers unfold themselves

Point it at a .pst, .ost, or .mbox and it walks every folder, queuing tens of thousands of messages from a 2 GB store without you opening each subfolder by hand.

A real batch, not one click per email

Add files and folders in any mix, then batch convert emails to PDF in one run. Output as separate PDF per message, or merge whole list into a single combined file.

Keeps the email intact

The PDF keeps the original HTML layout, inline images, and the From/To/Date/Subject headers, rendered through wkhtmltopdf so a message looks like it did in the inbox.

PDF, HTML, or plain TXT

PDF is the default for archiving and sharing. Save as HTML to keep a web-ready copy, or TXT when you only need the words. That last one is handy for dropping a thread into a search index or a summarizer.

Runs on your machine

Reading the source and building the PDF both happen on your PC. There is no sign-up and no upload step.

Who uses Email to PDF Converter

Legal, HR, and compliance

eDiscovery sets, case files, and audits need every item accounted for, not a sample. A mixed pile of .msg and .pst converts in one defensible pass, and the count of PDFs out matches the messages in.

IT admins and people switching mail apps

Leaving Outlook or Thunderbird, clearing out stale .pst and .ost archives, or moving a departed employee's mailbox into records. You can export Outlook emails to PDF without Outlook installed or running.

Anyone with old mail to read

An inherited .mbox, or a backup .pst pulled off an old laptop. Open it and save the parts that matter, without setting up original account again.

Mail formats it converts

One app covers the files Windows users actually end up with, from a single saved message to a multi-gigabyte Outlook store.

Format	Extension	Where it comes from
EML	.eml	Single messages saved from most mail apps (RFC 822)
MSG	.msg	Outlook messages dragged to disk (OLE/MAPI)
PST / OST	.pst, .ost	Outlook mailbox archives and cached accounts
MBOX	.mbox	Thunderbird, Apple Mail, and Unix mailboxes
Output	.pdf, .html, .txt	Pick per message or one combined file

🙋 Frequently Asked Questions

❓ Do I need Outlook or Thunderbird installed?

No. The app reads the saved .eml, .msg, and mailbox files directly, so the mail client that created them does not have to be installed or running.

❓ Is my email uploaded anywhere?

Short answer: no. Long answer: reading the file and rendering the PDF both run on your PC, which is the reason legal and HR teams reach for a desktop tool instead of a web converter when the mail is confidential.

❓ Which email formats can it convert?

EML and MSG messages, plus Outlook PST, OST, and MBOX archives. The output is PDF, with HTML and TXT available when you prefer them.

❓ Can it convert a whole PST or MBOX at once?

Yes. Point it at the container and it expands every folder and message into the queue. You can also tick only the folders or messages you need before the run starts.

❓ Does it keep attachments and formatting?

It preserves the HTML layout, inline images, and the From/To/Date/Subject headers in the PDF. Turn Include images off when you want lighter, text-only output.

❓ Can I merge several emails into one PDF?

Yes - choose combined output for a list of EML and MSG messages. For very large containers, one file per message is usually easier to file and search later.

❓ Will it run on Windows 11?

Yes, it runs on Windows 10 and 11. There is no Mac build today.

❓ How is this different from your EML or PST to PDF tools?

Each of those single-format apps reads one type of file. There is EML to PDF for saved messages and MSG to PDF for Outlook items, then PST to PDF and MBOX to PDF for the big archives. This one reads all of them, so a mixed archive converts in a single tool instead of four. Pick a format-specific app when you only ever deal with that one format.
