Source coverage
The email converter software reads thirteen file types, grouped below by the program that wrote them. Mix several in one run if the mail is spread across them.
Servers
Contacts
Not sure which file you have?
Open it first with a free viewer. Neither costs anything and neither changes the file.
Core features
Four screens, in the order a conversion runs.
Profiles found for you
Pick a desktop client and Email Converter Software locates its configured profile for you, instead of asking you to find it inside AppData. Outlook, Thunderbird and eight others are located on their own. Loose files load by browsing to them.
Selective conversion
The file opens as a folder tree with a checkbox on every branch. One quarter of one sender comes out on its own. So does everything except junk.
Message preview
Messages open in a preview pane before anything is written. Alongside the reading view sit four analysis views, which is what forensic and IT users come for when a file has arrived from somewhere they do not control.
Output options
The output format is picked last, after the preview. Document formats carry a naming scheme, so a folder of thousands of PDFs stays searchable. Attachments or addresses can be pulled out on their own.
Before you start
Conversion happens entirely on disk. If a live mailbox is involved at either end, one of the other three tools is the right one.
Covered here
File to file
An MBOX you want as PST. A folder of EML you want as one PDF. Nothing signs in anywhere.
Different tool
Mailbox to file
Pulling mail out of a live account first? Start with the email backup software, or its provider pages: Gmail backup tool, Outlook.com backup tool, Hotmail backup tool, Office 365 backup tool and Yahoo backup tool and the iCloud backup tool, Webmail backup tool, Google Workspace backup tool.
Different tool
File to mailbox
Putting a saved file back into an account is what the email recovery software does.
Different tool
Mailbox to mailbox
Moving one account into another is handled by the email migration tool.
All four share one download. The mode is picked once Email Converter Software is open, so trying the wrong one costs nothing. Opening a file to read it, with no output at all, is the free email viewer software.
Free demo
Run it on your own file first
Install it, load the file, select what you need and pick a format. Nothing is written until you start the conversion.

Common questions
What Email Converter Software reads, what it writes and where it stops.
No. Email Converter Software reads PST, MBOX, OLM and the rest on its own, so a machine with no Outlook and no Thunderbird can still open and convert their files. That is the usual reason people choose it in the first place.
Neither. Conversion is a disk operation from start to finish. Nothing signs in, nothing uploads and the machine can be offline the whole time.
No. The source is opened read only and the output is written to a folder you pick. Run the same file again next week and it behaves the same way.
Yes. Point it at a folder and every supported file inside is queued together. Files of different types can sit in the same run. The output can be one combined file or one per source.
Thirteen go in: PST, OST, MBOX, EML, EMLX, MSG, DBX, OFT, OLM, vCard, Zimbra TGZ, CommuniGate and Maildir. Eight come out: PST, MBOX, EML, MSG, PDF, HTML, CSV and TXT, plus vCard and ICS for contacts and calendar entries.
No. Repair rebuilds a broken file structure, which is a different task from reading a sound file and writing a new one. Repair the file first using our repair PST file without ScanPST, then convert it here.
Yes. The folder hierarchy is rebuilt in the output. Attachments, inline images, dates and the To, Cc, Bcc, From and Subject fields all carry across. There is also an option to flatten the hierarchy if a single flat folder suits you better.
No. A large archive needs disk space for the output and takes longer to write, but nothing stops part way. Speed depends on your own disk rather than on a network connection.
Yes. Whatever the source holds comes through, so contacts, calendars, tasks and notes convert alongside the mail. Contacts can be written as vCard and calendar entries as ICS.
No. Email Converter Software is a Windows application only, from Windows 7 through Windows 11 and Windows Server 2008 through 2025. There is no macOS or Linux build, although it does read OLM files written by Outlook for Mac.
Every preview, filter and format is unlocked in the demo. Only the writing is capped, at 10 files, which is enough to see whether the output opens cleanly at the other end.
Yes. Under Extract there are separate options for attachments, email addresses and phone numbers, so those come out without converting whole messages.

User testimonials
Across 683 reviews of the backup and restore wizard.
Collected across 683 reviews from software directories and direct customer feedback. The three below are unedited.
I just wanted to convert emails from Gmail to PDF format. After purchasing this email conversion tool on a deal, I realized that apart from this, it can also convert emails from multiple platforms. Also, they provide dedicated support team that assist users 24*7 via live chat and email support.
I had to convert several emails from my Yahoo account to PDF format. Also, the emails I wanted to convert were from a particular sender. After I got tired of searching all possible manual methods I asked a colleague. He suggested this app and the software performed well.
I had a bunch of AOL mails that I needed to convert and move into Outlook PST format. A quick Google search led me to this mail converter software. After reading all the specs and reviews, I gave this email conversion tool a shot. The interface is pretty simple, so I did not face any difficulties during the conversion process.
