Open and read a .eml email in your browser - headers, formatted body and attachments. Free, nothing is uploaded, remote content is blocked for your privacy.
EML Viewer for Windows opens whole folders of .eml files at once, searches them by subject, sender or file name, and prints or saves any message - offline, with no upload.
Saved emails usually sit in Downloads or the folder where you exported a mailbox. The viewer accepts only names ending in .eml or .msg, so add .eml to a forwarded message saved as plain "attachment".
Drag and drop the EML file onto the box at the top of the page, or click the box and pick it. Large messages are processed in the background, so the tab keeps responding.
The header comes first, then the text of the email message. A note that remote content was blocked means the words are all there and only pictures hosted on web are missing.
Click Download next to an attachment to save it. For another message, click Open another email and drop in the next file.
An EML file is one email saved as plain text in the standard internet message format, RFC 5322. The single file contains the message, attachments, and pictures as encoded text in MIME parts. Thunderbird, Apple Mail, and new Outlook can save messages this way, and many webmail services let you download a message as .eml. See how the parts fit together in our EML format guide.
Loose .eml files mostly come from outside the mail app you use every day, such as a help desk ticket.
Your browser reads the .eml into memory, and a Web Worker on the page takes it apart. The content is not sent to our server.
Newsletters and phishing emails often hide a tiny 1x1 picture on the sender's server. When a mail app loads it, the sender learns that you opened the message, when, and from which IP address. Here, remote pictures and CSS backgrounds are blocked by default, and a note tells you so. Show images loads the https pictures, including the pixel, so it deserves a second thought. Scripts, forms, and embedded frames are cut from the message either way.
EML Viewer Online puts From, To, Cc, Subject, and Date above the message. An address group, such as a "Team" list with two people, is split into separate addresses, and the date uses your system's format. The Cc field appears only when the email has one. Bcc is not displayed.
An HTML email keeps its tables and colors. Pictures embedded in it, such as a logo in a signature, come from the file itself and appear without going online. Without HTML, plain text uses a fixed-width font. Web fonts are not loaded, so a heading may use a standard font instead of the sender's.
The Attachments (N) list gives each file's name and size in B, KB, or MB. Pictures used inside the message carry an inline mark. Download saves a file to your disk without opening or running it in the browser. Slashes in a file name are replaced, so every file lands where your browser keeps downloads.
An email forwarded inline appears in the body with its own small header, and its attachments join the main list. This works up to 10 levels deep. A message attached as a separate .eml appears in the list instead. Download it and open it with Open another email.
An .eml is plain text, so Notepad or any text editor will open it. That works for a quick look at the headers, not for reading the message.
The page takes the MIME structure apart like an inbox and gives you the result. Each section is decoded with the character set it declares, so Cyrillic or Japanese usually reads fine. The raw source stays out of sight.
An .eml is readable text built to a public standard, while an .msg is the binary container that Outlook for Windows writes. The extension tells you which one you have, and renaming a file does not change what is inside it. The box accepts both. For an Outlook file, MSG Viewer Online walks through the .msg side of the same tool.
No. EML Viewer Online shows a message, does not save it in another format, and has no Print button. You can save each attachment through its Download button, and select and paste the text into Word or Notepad. For a PDF copy, use EML to PDF Converter, a Windows program made for that job. The desktop EML Viewer also does not create PDFs; it saves a message as EML or HTML.
On a Mac, Apple Mail usually opens an .eml with a double-click. On Windows, the double-click goes to the default mail app, or Windows asks which app to use when there is none. On Linux or a Chromebook with no mail app set up, load this page in an up-to-date browser.
Recent Outlook for Android opens an .eml attached to an email, but a loose .eml file in Downloads depends on the apps you have. Our desktop EML Viewer runs on Windows only.
Read one email in a browser on any computer, or work through folders of them offline on a Windows PC.
The Download button gets the desktop EML Viewer with a free trial. The online viewer needs no download, it is already at the top of this page.
