# EML reader & email viewer — open .eml, .msg & .mbox, no upload

> Free EML reader and email viewer: open .eml, .emlx, Outlook .msg and .mbox files in your browser, no signup and no upload. Works without Outlook.

Open and read .eml, .emlx, Outlook .msg, and .mbox email files right in your browser — a free EML reader and email viewer that needs no Outlook, no signup, and no upload. Remote images and trackers are blocked by default so opening a message can't phone home.

An .eml or .msg file is just a saved email, but opening one usually means firing up a heavy desktop client or trusting an online viewer that uploads your message first. This reader skips both: point it at the file and the message renders in the tab, so a forwarded receipt, an exported thread, or evidence attached to a ticket stays on your machine.

It handles the formats people actually run into — .eml from most mail clients, .emlx from Apple Mail, Outlook .msg, and full .mbox mailboxes from Gmail Takeout or Thunderbird. You get the formatted body plus the subject, sender, recipients, and date, and you can expand the raw headers when you need to see exactly how a message was addressed and routed.

When you need more than a read: convert the message to a shareable PDF with Email to PDF, pull files out of it with the Attachment extractor (including stubborn winmail.dat), or trace its delivery path with the Header analyzer.

## How to

1. **Add the email.** Drop an .eml, .emlx, .msg, or .mbox file onto the tool, or browse for it.
2. **Read the message.** See the formatted body, subject, sender, date, and recipients laid out like a mail client.
3. **Check headers & attachments.** Expand the full headers or the attachment list to inspect what came with the message.
4. **Open the next one.** For an .mbox mailbox, pick any message from the list to read it.

## FAQ

### How do I open an EML file without Outlook?

Drop the .eml file onto this page. It renders the message — body, headers, and attachments — in your browser, so you don't need Outlook, Thunderbird, or any desktop app.

### Can I open an Outlook .msg file?

Yes. The viewer reads Outlook .msg files as well as .eml and .emlx, showing the message and letting you save its attachments — a quick way to read a .msg file without Outlook installed.

### What is an .emlx file and can I open it?

EMLX is the per-message format Apple Mail uses on macOS. Drop an .emlx file here and it opens the same way as a standard .eml message.

### Can I open an MBOX mailbox?

Yes. Load an .mbox export (from Gmail Takeout, Thunderbird, or Apple Mail) and the tool lists every message inside so you can read them one by one.

### Is this email viewer really free?

Yes — it's a free EML viewer with no account, no watermark, and no upload. The whole thing runs as a static page in your browser tab.

### Are remote images and trackers blocked?

By default, yes. Remote images and tracking pixels are not loaded when a message opens, so viewing an email can't signal the sender that you read it.
