# Extract email attachments & open winmail.dat, no upload

> Free tool to extract attachments from .eml, .msg and .mbox emails and decode winmail.dat (TNEF) files in your browser. Save one file or all as a ZIP, no upload.

Pull every attachment out of .eml, .msg, and .mbox emails, and decode stubborn winmail.dat (TNEF) files other apps can't open. Preview, save one file, or download them all as a ZIP — entirely in your browser.

Attachments are often the reason you saved an email in the first place — the invoice PDF, the signed contract, the photos. Getting them out shouldn't mean forwarding the message to a web service that keeps a copy. This tool reads the email locally and lets you lift the files straight out.

It also handles winmail.dat: the TNEF container Outlook occasionally sends that hides the real attachments from other mail clients. Decoding it here turns that dead-end file back into the documents it was carrying.

Once you have the files, read the source message in the Email viewer, turn the email itself into a PDF with Email to PDF, or check where it came from with the Header analyzer.

## How to

1. **Add the email.** Drop an .eml, .msg, or .mbox file (or a winmail.dat) onto the tool.
2. **See the attachments.** Every embedded file is listed with its name, type, and size.
3. **Preview or select.** Preview supported files, or pick the ones you want.
4. **Save.** Download a single attachment or the whole set as a ZIP.

## FAQ

### How do I open a winmail.dat file?

Drop the winmail.dat onto the tool. It decodes the TNEF wrapper Outlook sometimes sends and reveals the real attachments inside so you can save them.

### Can I extract attachments from a .msg file?

Yes. The extractor reads .eml, .msg, and .mbox messages and lists every attachment for download.

### Can I save all attachments at once?

Yes. Select the files you want — or all of them — and download the set as a single ZIP.

### Are the attachments uploaded anywhere?

No. The email is parsed in your browser tab and the attachments are written straight to your device.
