PST to EML converter — extract every message as a .eml file
Drop a .pst file and export its messages as individual .eml files, zipped with the folder structure preserved. Each .eml is a standard RFC 822 message with its attachments embedded — openable by any mail client. Everything runs locally.

How it works
Drop your .pst file
The archive is parsed in this tab — never uploaded. Browse folders and open messages to check them first.
Export as EML zip
Choose "EML files (.zip)" in the export row. Messages are written one .eml each under their folder names, with attachments embedded as MIME parts. The free tier covers the first 10 messages.
Use the .eml files anywhere
Double-click an .eml to open it in Outlook, Thunderbird, Apple Mail or Windows Mail; or drag the whole set into any client that imports EML. Single messages can also be saved straight from the reading pane, free.

Frequently asked questions
How do I convert PST to EML?
Drop the .pst file into the box above, select "EML files (.zip)" in the export row, and click "Export all". You get one zip containing one .eml per message, arranged by folder. No upload, no Outlook, no account.
What is an .eml file?
The standard single-message email format (RFC 822): headers, body and attachments in one plain-text file. Every mail client — Outlook, Thunderbird, Apple Mail, Windows Mail — opens .eml files directly, so it is the most portable way to keep or share individual messages.
Are attachments included in the .eml files?
Yes — each .eml carries its attachments as base64 MIME parts, exactly as stored in the PST. Open the .eml in any mail client and the attachments are there.
Can I save just one message?
Yes — open the message in the reading pane and click "Save this message as .eml". Single-message saves are free (up to 10 per file); bulk extraction of the whole mailbox is the licensed export.
What's free and what does a license unlock?
Free: viewing everything, single attachments, single-message .eml saves, and a full-format export of the first 10 messages — unlimited times. A one-time license (3-month $14.99 or lifetime $29.99) removes all limits and adds bulk attachment extraction and cross-folder search.
Is my mail uploaded anywhere?
No — parsing and .eml assembly happen entirely in your browser tab. Verify in the Network tab of developer tools: the only requests are page loads, an anonymous usage counter, and license validation for paid users.
