Offline Desktop EML Viewer
Professional tool to view your EML files on your computer
4.8/5 (Trusted by Users)
EML Reader is a free online viewer for .eml files. Drop your file into the box above and the message renders in your browser, including the headers, the body text and any attachments. Nothing uploads to a server. Nothing is stored online. Your file stays on your device the whole time.
Works In Every Major Browser
Chrome, Edge, Firefox, Safari, Brave. On Mac, Windows, Linux, ChromeOS, iOS or Android.
Once this page loads, file processing happens entirely on your device.
Three Steps
From file to readable message in under ten seconds. No login, no upload.
Drop an .eml file into the box at the top of this page. Or click Select to browse from your computer.
Click Preview Message to render the email. The viewer shows headers, body text and any inline attachments.
Scroll through the message. Click any attachment to preview it inline or save it to your device.
Background
EML files are single email messages saved as standalone files. Each file holds one email with its headers, body text and any attachments, separate from any inbox or mail server.
Email clients like Outlook, Thunderbird and Apple Mail can save messages this way. Forensic tools, archive systems and legal disclosure software often export to .eml as well. The format follows RFC 5322, the same standard that defines email messages on the internet.
If you receive a .eml file as an attachment, or export one from a mail client, this viewer opens it the same way any inbox would.
Why It Works
Open files in any browser. No software to install, no admin rights needed, no portable runtime to download.
Mac, Windows, Linux, ChromeOS, even tablets and phones. If the browser opens, the viewer opens.
Drag-and-drop or select a file. The message renders in seconds. No upload wait, no processing queue.
Three clicks from file to message. No menus to learn, no settings to configure, nothing to set up.
See the complete header information. Sender, recipient, dates, routing data. Plus inline attachments.
Your .eml never leaves your browser. The viewer reads it in JavaScript and never touches our servers.
Privacy First
EML Reader processes files locally in your browser. We have no way to see your messages, your attachments or your contacts.
Chrome Extension
Install the Chrome extension to open .eml files directly from your downloads folder, without visiting this page each time. For a wider tour, see our complete guide on opening EML files in Chrome.
Open Chrome and go to the Online EML Viewer plugin page. Click Add to Chrome to install. Once installed, you'll see the extension icon in the top-right of your browser. Click it to open.

Click Open Email. This opens a file picker where you browse your computer and select the .eml file you want to view.

Select the .eml file. Click Open.

The message opens with full content and any attachments. Attachments may show as icons or links. Click them to preview inline or download to your device.

Click the trash icon to remove a message from the list at any time.

Questions
Quick answers to the questions people ask most often about reading .eml files.
Outlook, Thunderbird and Apple Mail all handle .eml files natively, though Outlook sometimes needs a quick fix when files do not open. EML Reader opens them in any browser without installing anything. Forensic tools like Magnet AXIOM and OSForensics also support .eml.
Yes. Use this site directly, or install the EML Reader Chrome extension for one-click access. See our complete guide on opening EML files in Chrome for other methods.
For a single file, EML Reader opens it in the browser without any setup. For ongoing work with many .eml files, an offline desktop email client (Thunderbird is free, Outlook is paid) gives you mail-management features beyond just viewing.
No. The viewer reads files in your browser using JavaScript. Nothing uploads to our servers, nothing is stored on our end, nothing is sent to third parties. See our privacy policy for the full picture.
Yes. The extension is free on the Chrome Web Store. No subscription, no ads, no in-app purchases.
Most webmail providers do not import .eml files directly. The simplest route is to open the file in EML Reader, then forward the content to yourself from a desktop client. For client-specific steps, see our guides on opening EML files in Gmail and Yahoo Mail.
Yes. To save an email as PDF, open it in your browser and use your browser's Print function with Save as PDF as the destination. For batch conversion to Outlook's PST format, see our guides on converting EML to PDF and converting EML to PST.
