Free MSG to EML converter
Turn Outlook .msg files into standard .eml messages any mail client can open — one file or a whole batch.
- 100% in your browser — never uploaded
- Batch convert + .zip download
- Free, no signup
No .msg files handy? Outlook creates them when you drag messages to a folder or use File → Save As inside a message.
How it works
Your email never leaves your device
01
Drop your .msg files
Select or drag in one file or dozens — exports from Outlook's drag-and-drop, File → Save As, or an old archive folder.
02
Converted locally
Your browser decodes Outlook's binary container and rebuilds each message as a standards-compliant RFC 822 .eml — bodies, addresses, and attachments included.
03
Download .eml or .zip
Save each converted file on its own, or grab the whole batch as a single .zip. Nothing was uploaded — reload the page and it's gone.
Why convert .msg to .eml?
A .msg file is locked to Microsoft's proprietary Outlook format — Apple Mail, Thunderbird, and most archive and e-discovery tools simply can't read it. The .eml format is the open standard (RFC 822/5322) that mail software has shared for decades: convert once, and the message opens anywhere, forever. Want to inspect a file before converting?

FAQ
Why convert .msg to .eml?
.msg is Outlook's proprietary binary format — Apple Mail, Thunderbird, Gmail import tools, and most archiving systems can't open it. .eml is the internet's standard message format (RFC 822/5322): open it anywhere, index it, and keep it readable for decades. If you're archiving email for the long term, .eml is the format to keep.
Can I convert many .msg files at once?
Yes. Select or drop as many files as you like — each one is converted the moment it lands, and with two or more converted files you get a "Download all" button that packs every .eml into a single .zip. It all happens in your browser, so there's no per-file or size limit from us.
What exactly is preserved in the conversion?
The subject, sender, To/Cc recipients, date, the plain-text and HTML bodies, and every attachment (including inline images). One honest caveat: if a message's only body is Outlook's RTF format and it can't be recovered as HTML, the .eml gets the plain-text body instead, so formatting is simplified. And because the .eml is rebuilt from the message's content, the original transport headers (the Received chain) aren't included.
Are my emails uploaded to your server?
No. Parsing and conversion run entirely in your browser — the files never leave your device. You can load this page, disconnect from the internet, and keep converting.
What's the difference between .msg and .eml?
.msg is an OLE/CFB binary container that stores Outlook's internal MAPI properties; .eml is plain MIME text, the same bytes mail servers exchange. Same message, but only one of them is portable. Read the full guide: What is a .EML file?
Can I check a file before or after converting?
Yes — open the original in the MSG viewer to read it first, and open the converted result in our EML viewer to double-check it. You can also turn a converted .eml into a printable PDF with the EML to PDF converter: EML to PDF converter
