Convert PST to EML — one file per message
Turn an Outlook .pst archive into individual .eml files — one per message, openable in Windows Mail, Thunderbird, and most mail clients. Read and converted locally, never uploaded.
Drop the .pst file — it is read locally in your browser.
Preview any message, then export it as EML for free.
With a license, export a whole folder as a ZIP of EML files.
Open the EML files in Thunderbird, Windows Mail, or your client.
Convert PST to EML — one file per message
Use this converter when you need each message as its own file — for evidence, per-message review, or importing selected mail elsewhere. Mailward reads the PST in your browser and writes standard EML, preserving headers and body.
Exporting a single message is free; bulk export of a folder or the whole archive to a ZIP of EML files is the paid step. The archive stays on your device the entire time.
On a Mac? macOS has no readpst and new Outlook for Mac won't export mail files. A browser tool is the one path that doesn't need a Windows machine.
Converting this file
Q. What opens an EML file?
Thunderbird, Windows Mail, Apple Mail, and most desktop clients open EML directly. Many open it just by double-clicking the file.
Q. Can I export the whole folder at once?
Yes, with a Pro license — a whole folder or archive exports as a ZIP of EML files. Single-message export is free.
Q. Are attachments included?
Message bodies and headers export in this first release; full attachment re-embedding in the EML is on the near-term roadmap. Attachments can already be pulled separately.
Q. Is anything uploaded?
No. The PST is parsed in a Web Worker on your machine and the EML files are generated locally.
