An EML file is a type of file used to store individual email messages. It contains the email's content, including the subject, sender, recipient(s), date, and body, as well as any attachments. EML files are commonly created by email programs like Microsoft Outlook or downloaded from GMAIL and can be opened with various email clients or text editors. They are used to save, share, and archive emails outside of email clients.

What Is an EML File and What Can You Do With It?

An EML file is a plain-text snapshot of a single email message stored in a format defined by RFC 822. Every email you download from Gmail, Outlook, Yahoo, or Apple Mail comes out as a .eml file that contains the full message: headers, subject, sender, recipients, the HTML body, any plain-text fallback, and encoded attachments.

This tool parses that raw EML content entirely in your browser and lets you do two things: see a rendered visual preview of how the email actually looks, or pull out the raw HTML source code so you can inspect, debug, or repurpose the template.

🔌

Export from Any Email Client

Works with EML files from Gmail, Outlook, Yahoo Mail, Apple Mail, Thunderbird, and any client that exports the standard .eml format.

📺

Rendered Email Preview

Extract the HTML Source

Pull the raw HTML out of any EML file to inspect the template code, recover a lost email design, or debug rendering issues in a specific email client.

Privacy note: This tool processes your EML content entirely in your browser. Nothing is sent to a server. Your email data stays on your device.

Frequently Asked Questions

An EML file is a standard email message format that stores a single email, including the subject, sender, recipients, date, body, and any attachments. EML files follow the RFC 822 standard and can be exported from Gmail, Microsoft Outlook, Apple Mail, Yahoo Mail, and most other email clients.

Open the email in Gmail, click the three-dot menu (More) in the top right of the message, and select "Download message." This saves a .eml file to your computer. Open it in any text editor (Notepad, TextEdit, VS Code), copy the entire contents, and paste them into the tool above.

In Microsoft Outlook, you can drag an email directly from your inbox onto your desktop and it will save as a .eml file. Alternatively, open the email and go to File > Save As and save as a .msg or .eml file depending on your Outlook version. Open the file in a text editor, copy the contents, and paste into the tool above.

Preview mode renders the HTML content of the email in an iframe so you can see the visual layout: images, colors, fonts, and structure. View HTML mode shows you the raw HTML source code extracted from the EML, which is useful for debugging email templates, recovering a lost design, or checking what code was actually sent.

Yes. This tool processes everything in your browser using client-side JavaScript. Your EML content is never sent to a server or stored anywhere. All parsing happens locally on your device, so private or sensitive email content stays private.

Yes. If you have an EML copy of an email campaign, transactional email, or any HTML-based message, you can paste it into this tool, switch to View HTML, and copy the HTML source code. This is a practical way to recover a template from an archived send when the original file is no longer available.
