Quick answer
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
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.

4One 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.

Core features
Five screens of Corbett EML converter software, in conversion order.
Source files
Select Open, then Email Data Files, and choose EML Files. EML converter loads your messages into its panel, and no mail client is needed.
A spare PC with no Outlook or Thunderbird still works. EML file converter reads your files and leaves them as they were.
Batch loading
Select Choose Files for one message or a few. Select Choose Folders to load an entire directory of EML files in one step.
Loaded mail appears in one tree with a checkbox beside every item, so EML converter handles many EML files in a single session. No file size limit applies.
Message preview
Click any message and a reading pane opens beside five analysis views. Use them to confirm correct mail before an export starts.
Content shows the email body. Message header lists From, To, Subject and Date. Properties reports message data, while hex and raw message views show the stored mail.
Output formats
Email files export to PST or MBOX. Document files export to PDF, HTML, TXT or CSV. The Export menu also lists Gmail, Office 365, IMAP and Thunderbird for sending mail into an account.
Search by keyword first, then save only matched items. Quick search highlights hits in yellow, and Advance search checks every field or only name, subject, To, Cc and content.
Export options
Switch on open folder after export, skip greyed out folders, create empty folders and include email headers. For PST output, create an individual PST file for every folder, so small files stay healthy.
Select Browse to choose a destination, then Save. Live progress shows every folder as it converts. Need Outlook files? Open EML to PST Converter.
Working process
Four steps take your EML files to their new format. Try them on a few files in free demo first.
Add your EML files
Start EML converter, select Open, then Email Data Files and choose EML Files. Select Choose Files for one message or Choose Folders for many.
Preview and select mail
Your EML files load as one tree. Click any email to preview it, tick what you need and search by keyword to trim your conversion.
Choose your output

One saved message opens and prints fine from a mail client. A folder with thousands is another job. Here is where opening files by hand stops.
| Task | Manual opening | EML Converter |
|---|---|---|
| Cost | Free | From $99 one time |
| A handful of messages | Open and save by hand | Works too |
| Folders of EML files | One message at a time | One batch of files or folders |
| Output formats | Print or Save As | PST, MBOX, PDF, HTML, TXT and CSV |
| Data extraction | Copy by hand | Addresses, phone numbers and attachments |
| Filters | Folder search only | Date, time, To, From, size and name |
| PDF file names | Typed in by hand | Named by From, To, Date or Subject |
For one message your mail client does the job.

This is a wonderful application that allows you to convert EML files into various formats. I was looking for reliable EML converter software, and I am happy that I found Corbett software.
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.
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.
Before 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
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.
