EZPZ FileAn EML file opens straight in your browser, with no extension renaming. Drop the file and the sender, date, body and attachment list appear exactly as they were. Nothing to install, no account to create, and the file never leaves your device.
No upload
Drop your files here
Drop several .eml files, a folder or a ZIP to browse them like a mailbox. Files open only inside this browser.
Drop a message you downloaded or backed up. Several .eml files, a folder or a ZIP work too.
Sender, subject and date appear above the body. Switch between HTML and text.
Export the message as text or PDF, or pick out an attachment to download.
The most repeated advice for opening an EML file is to rename it to .mht. It does open: Windows treats the renamed file as a web document and hands it to a browser or to Word.
What follows is the problem. You cannot pull attachments out of it, tracking pixels in the message load as soon as it renders, and non-Latin mail frequently comes out garbled because the character encoding is read differently. You have also renamed the original file, which causes trouble later.
This viewer leaves the .eml file alone and reads it as EML. Nothing to rename, nothing to undo afterwards.
| Renaming to .mht | Online EML viewers | Opening in the browser (this tool) | |
|---|---|---|---|
| Extract attachments | No | Usually yes | Yes, one by one |
| Block tracking pixels | No | Varies by service | Blocked by default |
| File upload | None | Uploaded to a server | None |
| Character encoding | Frequently garbled | Usually handled | Follows the encoding the mail declares |
Plenty of email embeds a one-pixel transparent image in the body. The moment that image loads, the sender knows when and roughly where you opened the message. Marketing mail does it; so does fraudulent mail, to sort live addresses from dead ones.
So images loaded from outside are blocked, and you press a button to load them only when you want to. Images carried inside the message itself need no outside request and show up normally.
An email body is HTML that someone else wrote. Pasting it straight into the page would be dangerous, so it is drawn only inside a separate frame with scripts and outside access cut off, and a rule inside that frame blocks outside requests as a second layer.
For checking a security-training message or something that looks suspicious, this is safer than opening it in your mail client.
In Gmail, the menu at the top right of a message has "Download message", which saves an .eml. In Outlook, dragging a message into a folder produces one. Corporate mail backups and messages kept as legal evidence use the same format.
It will open, yes. But you cannot extract attachments, tracking pixels are not blocked, and non-Latin messages often come out garbled. You have also renamed the original file. This viewer reads the .eml as it is.
No. Parsing and display both finish inside your browser, so you avoid putting work or personal mail into an online viewer.
They are listed and downloadable one at a time. Once saved, you can run them through the other tools here.
Open the .eml, press "Save as PDF", then pick "Save as PDF" as the destination in the print window (on an iPhone, use the share button in the print screen to save it to Files). The PDF holds the subject, From, To, Cc, date and attachment list, then the body with its embedded images, then any image attachments. If the message loads images from the web it asks before including them, and other attachments such as PDF, Word or ZIP files are not in the PDF, so save those separately from the list.
Yes. Drop several .eml files together, pick a folder with "Choose folder", or drop a ZIP with .eml files inside, and the viewer becomes a mailbox: a list on the left, the selected email on the right. You can search sender, subject and body, filter by the folders inside the ZIP or folder, and show only mails with attachments. "Save all as PDF" puts the listed mails into one PDF, and "Download all attachments (ZIP)" collects every attachment with one folder per mail. Up to 1,000 emails open at once. Outlook .msg files are not supported.
Character encoding varies between messages and occasionally trips things up. Switch to the text view and see if that reads better.
Not supported. The .msg format is Outlook-only. Save as .eml from Outlook first.
A request goes out to wherever the images live at that moment, and the sender can tell you opened the message. Only do it for senders you trust.
Someone wants "that email as a PDF". All you have is a .eml file, maybe forwarded by a colleague or downloaded from Gmail, and no Outlook to open it with. Here is the quick way, the built-in ways, and what a PDF of an email does and does not keep.
Legal asks for "the original email". You save the message and get a .eml file that does nothing when you double-click it.
You double-click a zip and Windows or macOS shows an error, or tells you the folder is empty. Find your exact message in the table below to see what it usually means and what to try, including password-protected zips and file names that come out as gibberish.
