Univik Online EML Viewer
100% private. Your mail stays local
100%
A free online EML viewer for saved emails. Open a saved .eml or Apple Mail .emlx file and read the message, its pictures and every attachment in your browser in seconds. Nothing to install, and your files are never uploaded.
Or choose them from your device. Each message opens locally on your own computer, phone or tablet. The files never leave it.
Most sites that open email files upload them to a server first. This one does not. It is a light-weight page that your own browser runs on its own: it reads each .eml from your device and shows the message on screen. Nobody else sees your mail.
An email holds contracts, invoices, passwords and personal talk. None of it goes anywhere: no server, no account, no copy of your data. Even tracking pixels inside the message stay blocked until you allow them.
Phones and computers alike: Android, iPhone, iPad, Chromebook, Windows, Mac and Linux. Any up to date Chrome, Edge, Firefox or Safari does the job, with no mail account set up anywhere.
Photos show inside the message where they belong. PDFs, Office files, zips and anything else sit one click away, each with a Save button that keeps the original file name.
Pick a whole folder of exported mail or a .zip file. The tool lists every message with subject, sender and date, lets you sort and search. A message is read only once you click it.
Quick answer: Univik Online EML Viewer opens saved .eml emails on Android, iPhone, iPad, Chromebook, Mac, Linux and Windows. Any recent browser works. You do not need Outlook, and your messages stay on the device.
Double-clicking an .eml only works when a desktop mail app is installed and set as the default. On a fresh PC, Windows has no built-in reader for these files. Drop the file on this page instead and read it in Edge or Chrome.
On macOS, Apple Mail can show an .eml, but only through the Mail app and its account setup. In Safari or Chrome, choose the file here and read it with the attachments, even on a Mac that has no mail account at all.
An .eml sent through a chat app or saved from a website often will not open on iOS. Save it into the Files app, open this page in Safari and tap Choose EML files. The message opens in the same tab, attachments included.
iPadOS Safari shows the complete three panel layout with the message list, details, zoom and downloads. Store the .eml files in the Files app and pick a whole batch in one go.
Works in Chrome, Firefox and Samsung Internet, on tablets as well as phones. Pick the .eml from Downloads or Google Drive. Everything is read on the device, so it works even in airplane mode.
On ChromeOS there is no desktop Outlook and no built-in reader for saved emails. This page fills that need. Choose the file from Files or Google Drive and it opens in Chrome, with the formatting and pictures intact.
Ubuntu, Fedora, Mint or Arch, any version of Linux that runs Firefox or Chromium. No Thunderbird or Evolution setup needed for a quick read. Message, headers and attachments show in the browser.
Mobile mail apps show your connected account, not a single .eml file someone sent you. This page opens that file with no app to download, and the layout adjusts to a phone screen.
Every saved message is read using the internet mail standards RFC 5322 and MIME, so whatever the sending program wrote into the file is what you see.
Every email opens with two views of the same message. The HTML tab shows the layout, colors and pictures the sender designed. The Text tab shows the plain wording, easy to read and copy. A Raw tab adds the source for anyone who needs it.
From, To (the recipient), Cc, Reply-To, subject, date and Message-ID up top, with the full header list one tab away: Received steps, DKIM results and everything the mail servers added along the way.
Photos and signatures built into the email show inside the message where the sender placed them. Attached PDFs, Office documents, zip files and audio each get a Save button with the original file name.
UTF-8 mail from today and legacy encodings from decades of email: Japanese ISO-2022-JP, Chinese GB2312 and Big5, Korean EUC-KR, Cyrillic KOI8-R, Hebrew, Arabic, Thai and the Windows code pages. Base64 and quoted-printable text are turned back into normal text automatically.
A forwarded email attached inside another email opens with one click and appears in the list as its own entry. Meeting invites show up as calendar attachments you can save as .ics files.
Newsletter images that load from a remote server can tell the sender you opened the email. The viewer leaves them not loaded and shows a Load remote images button, so reading an old email never signals the sender.
Drag one or more .eml files onto the drop area above, or press Choose EML files. A folder of saved emails or a .zip of them works too and each source keeps its own group.
Subjects appear on the left with sender and date. Click an email to read it, switch between the HTML, Text and Raw tabs and use the arrow keys to move through the list.
Click any attachment button under the subject, or use the Attachments tab on the right, to save pictures, PDFs and other files with their original names.
Univik makes both tools. This online page is the quick way to open EML files and read saved emails on any device. The Univik EML Converter for Windows turns entire folders of EML files into PDF, Word and other popular file types in a single batch run.

Clear answers about reading saved .eml emails in a browser, on any device, without Outlook.
No. The page you are looking at is the whole program. It reads the .eml from your disk and shows the message on screen, with no server involved at any point. To see this for yourself, turn off the internet and the page keeps working.
Open this page, choose the .eml and the message appears with its pictures and attachments. Nothing gets downloaded and no account is asked for. Windows has no built-in reader for these files, so a PC without a mail app set up cannot open them on its own. This page opens them for you.
Yes, and it is completely free: no limit on how many messages you open or how large they are, and no sign up. Attachment saving, HTML copies and the text export are included at no cost.
In Gmail on a desktop browser, open the message, click the three dot menu in its corner and choose Download message. In the new Outlook for Windows and Outlook on the web, use Save as under the More actions menu. Dragging the message into a folder works there too. Thunderbird and Apple Mail save an .eml when you drag a message out of the window, and older apps such as Windows Live Mail and Outlook Express used .eml as their normal format. Classic Outlook for Windows saves .msg instead, a different format.
EML stands for electronic mail. An EML file is a single email saved in the plain-text form defined by RFC 5322, the same bytes that travel between mail servers, so it keeps the original formatting, headers and timestamps unaltered. The headers come first, then the body, often in a plain-text and an HTML version side by side. Attachments are stored inside that text as base64 code, which is why an email with photos can be several megabytes.
A file with a .eml extension usually turns up in a few ways: a message you saved or forwarded from Gmail, Outlook or Apple Mail; an export from a backup or email archiving system; a mailbox pulled from a departing employee; a Google Vault or Microsoft Purview export; or a set of records handed over for a legal review or an eDiscovery case. Because .eml keeps the full message and its headers unaltered, it is also the format cyber crime and digital forensics work relies on. Whatever the source, this page opens the file and shows what is in it, without adding it to any mail account.
Most emails carry the same message twice: an HTML version with the layout and pictures, and a plain text version for older programs. The HTML tab shows the designed message, safely, with scripts removed. The Text tab shows the plain wording, which is the one to copy from. When an email has only one of the two, the viewer fills the other tab from it.
Load this page in Safari or Chrome on the Mac and pick the .eml. Nothing gets installed and no mail account is touched. That matters when the file belongs to a case, a client or another mailbox that should stay separate from your own Apple Mail.
Save the .eml into Files on iPhone or into Downloads on Android, load this page in Safari or Chrome and tap Choose EML files. The message opens in the same tab with pinch to zoom, and every attachment can be saved to the phone.
Yes. Photos show inside the message where the sender placed them. Every attached file shows as a button under the subject and again in the Attachments tab, each carrying its size and a Save button. Files are turned back from their base64 form on your device and keep their original names. Attachments as .zip in the Download menu saves all of them at once.
Newsletters and marketing mail often load their pictures from the sender's server, and that request can act as a read receipt. The viewer keeps every remote picture blocked, so opening an old email tells the sender nothing. One click on the button loads them when you want the full layout.
The viewer reads the character set declared in each part of the message: UTF-8, the Windows and ISO code pages, Japanese ISO-2022-JP and Shift_JIS, Chinese GB2312, GBK and Big5, Korean EUC-KR, Cyrillic KOI8-R, Hebrew, Arabic, Thai and even old UTF-7 mail. Coded subjects and file names are turned back into normal text too. When a message lies about its charset, the tool falls back to a best guess instead of showing question marks.
Emails with hundreds of megabytes of attachments open fine. The list is built from the headers alone, a message is read in full only when you click it. An attachment is opened only when it is shown or saved. The memory in use matches the single email on screen, not every file you selected.
The EML format itself is plain text, so opening the file does not run any program on its own. The real risk in email is what a message contains: phishing links in the body and malicious attachments, such as programs or Office files that carry hidden auto-run code. This viewer lowers that risk. It shows the email with scripts removed, keeps remote and tracking images blocked until you allow them and never runs attachments, it only saves them. If the file came from a trusted source like your own export, your IT team or a legal record, it is safe to open. Still treat links and attachments from a sender you do not know with care, and scan a saved attachment with antivirus before you open it.
Yes. Select as many .eml files as you like, drop in a whole folder or pick a .zip file of exported mail. Each source keeps its own group in the list on the left, where you can sort by date, subject or sender, keep only emails with attachments and search across everything, message text included.
Some Outlook and Exchange setups wrap the real attachments in a bundle called winmail.dat, in a Microsoft format named TNEF. The viewer shows the file and lets you save it, but does not open what is inside. If these turn up often, the fix is on the sender's side: Outlook has to be set to send plain or HTML mail instead of rich text.
Not on this page. An .msg is Outlook's own special format and a .pst is a whole Outlook data file, both different from the open .eml standard. An .mbox mailbox holds many messages in one file, and the Online MBOX Viewer is built for those. To open old .dbx files from the legacy Outlook Express email client, without installing Outlook Express, use the Online DBX Viewer, a light-weight browser tool like this one. If you drop a mailbox file here by mistake, the viewer detects it, splits it and points you to the right tool.
Yes. An .emlx file is how Apple Mail on the Mac stores a single message. It is a standard email with a short size line and a small end marker that Apple adds. The viewer reads past those, opens the message the same way it opens an .eml and shows the body, headers and attachments. Pick one .emlx or a whole folder of them exported from Mail.
The file was really a mailbox, not one email. Some export tools save many messages into a single file with the .eml extension, which makes it an MBOX file. The viewer detects the pattern, splits the messages apart and lists every one, so nothing needs fixing on your side.
Yes. Once the page is open you can go offline and carry on reading files. No server is ever contacted, and remote pictures inside messages stay blocked unless you press the button, so not a single request fires.
For one email, open it here and use your browser Print option, then choose Save as PDF as the printer. That gives you a PDF of the message you are reading. This viewer also exports single HTML and text copies and saves attachments. To turn whole folders of EML files into PDF, Word and other popular file types in one batch run, use the Univik EML Converter.
Free and private, with nothing to set up. Your .eml files stay on your own device.
