Quick answer

What Is an EML Converter?

An EML converter opens saved EML email files and converts them into another format. Corbett EML Converter does that offline on Windows, so a folder of EML files from any mail client opens in Outlook, Thunderbird or a PDF viewer.

What it opens

Single EML files and entire folders of them

What it saves

PST, MBOX, PDF, HTML, TXT, CSV and more

Who uses it

Switchers, admins, lawyers and anyone with saved emails

Conversion scope

EML Converter for Any Mail Client

EML Converter Saves Piles of Saved Emails in One Format

An EML file is one saved message. An EML made in one mail client may not open in the next, and a folder full of them cannot be searched or archived easily. EML converter exports them in bulk to a format that suits your new program or records archive.

One message per file

Library of Congress EML format page says an EML file holds one message and follows RFC 5322 as text. That is why thousands pile up fast and are hard to search or archive. EML converter saves them in formats that suit your new program.

As a marketing associate, my work is around emails. I have tried various software in the past years. But, the way Corbett EML Converter works, I am impressed and suggest everyone to try it.

Michael Corner

Print with filters

Quite a reliable & interesting tool, it helps me to print EML files with data filters. I will recommend this EML migrator for instant & secure conversion results.

Jill Marcelo

Before conversion

Prepare Your EML Files for Conversion

Three short checks save a repeat session.

Keep EML files in one folder

Collect your messages into a single directory, so one load brings them all into EML converter.

Browse to a clean drive

Any drive or directory works. Select an output drive with plenty of space, because PDF output can take more room than EML.

Match the target program

Select the format your next program needs: PDF for records, PST or MBOX for mail clients, CSV for address lists.

After conversion, read Import EML to Gmail or Import EML to Thunderbird account.

Best practice

How to Keep Your EML Conversion Safe

An EML conversion only helps if your mail arrives complete. Four habits keep your data safe through it.

Back up first

Copy your original EML folder before you start. Keep 3 copies on 2 types of media with 1 copy off site.

Start with a few files

Convert one small folder with EML converter and open a few messages in your new format. Catch a wrong setting before a large job.

Check the count

Compare the number of EML files with the converted emails before you close the job.

Keep originals until checked

Store your source EML files until counts match. Delete them only after you open converted mail.
