01 / Fast steps
- Drop or select one or more .eml files.
- Each message is parsed: headers, body and attachments.
- Read the message right here, or download the printable PDF and the attachments.
EML Viewer
Drop an .eml file and read the email as it was sent: subject, sender, date, formatted body and every attachment, without installing a mail client. Tracking pixels and scripts are stripped before anything is displayed, and the message is never uploaded.

EML
02 / Best for
- Read an .eml someone sent you as an attachment, without importing it into a mail program.
- Recover the attachments of an email exported from a mailbox that no longer exists.
- Inspect the real headers of a suspicious message to see the true sender and the route it took.
- Open a message on a computer where you cannot or will not configure a mail account.
03 / Why here
- Reads mail as it really is: folded headers, encoded subjects in any alphabet, nested multiparts, quoted-printable and base64 bodies.
- Images embedded in the email are shown; images hosted on a remote server are removed and counted, because loading one would tell the sender you opened the message.
- Scripts, iframes, forms and inline event handlers are stripped, so the saved page is safe to double-click years from now.
- Messages sent from Outlook in Rich Text hide their text inside a winmail.dat part, which is why most viewers show them as empty. Here the text is unwrapped and the files inside come out as attachments.
- Attachments come back as real files with their original names, including names written in non-Latin alphabets.
- The message is parsed in your browser tab and never reaches a server.
04 / Keep in mind
- Encrypted or S/MIME-signed messages are shown as their signature envelope: this tool reads mail, it does not decrypt it.
- Fonts and exact spacing of an HTML email depend on the mail client that displayed it, so the layout here is faithful but not pixel-identical to Outlook or Gmail.

Questions & answers
01What is an EML file?
An .eml file is one email saved as a file, exactly as it travelled: a block of headers (sender, recipients, subject, date, the servers it passed through) followed by the body and any attachments encoded as MIME parts. It is a plain-text format defined by internet standards, which is why any mail client can open one and why an .eml is the safest long-term way to archive a single message.
02Why are some images missing from the email?
Because they were never inside the message. Marketing and newsletter emails usually reference images hosted on a web server, and each one is a tracking pixel: requesting it tells the sender the exact moment you opened the mail, from which IP. This viewer does not load them, says how many it removed, and shows instead every image that genuinely travelled inside the email.
03Is my email uploaded to read it?
No. The file is parsed by JavaScript running in your browser tab and the readable page is written straight to your disk. It works with the network disconnected once the page is open. Email is correspondence, which is exactly why this tool has no upload step.
04Can I see the real sender of a suspicious email?
Yes, and it is one of the better reasons to use a viewer like this. The From line is trivially forged, but the Received headers are added by each server that handled the message and are much harder to fake: read from the bottom up, they show the route the mail actually took. The full header list is included in the downloadable page, alongside authentication results like SPF and DKIM when the receiving server recorded them.
05Why do some EML files open with no text at all?
Because the message was sent from Outlook in Rich Text format, which packs the body, the formatting and the attachments into a single proprietary part called winmail.dat instead of writing them as readable MIME. A viewer that does not understand that container shows an email with headers and nothing else, which is why so many of them appear to fail on Outlook mail. This viewer opens the container, so the text appears and the files inside it are offered as normal attachments.
06Is EML Viewer free?
Yes, completely free, with no sign-up and no limits. It runs in your browser, so your messages never leave your device.
