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 email and read the message, its pictures and every attachment right in your browser. 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, decodes it 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 say otherwise.
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 archive. The tool lists every message with subject, sender and date, lets you sort and search. A message is decoded 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 distro that runs Firefox or Chromium. No Thunderbird or Evolution setup needed for a quick read. Message, headers and attachments render in the browser.
Mobile mail apps show your synced 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 parsed against 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, clean and quotable. 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 hops, DKIM results and everything the mail servers added along the way.
Embedded photos and signatures render inside the message where the sender placed them. Attached PDFs, Office documents, archives 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 are decoded 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 live on a remote server can tell the sender you looked. The viewer leaves them unloaded 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 chip 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 for reading 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, decodes it and draws the message on screen, with no server anywhere in the chain. The proof: turn the internet off and it carries on working.
Open this page, hand it the .eml and the message appears with its pictures and attachments. Nothing gets downloaded and no account is asked for. Windows itself has no built-in reader for these files, so a PC without a configured mail app hits a wall that this page walks around.
Yes, and free means free here: no cap on message count or size, 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.
An EML file is a single email in the plain-text form defined by RFC 5322, the same bytes that travel between mail servers. The headers come first, then the body, often in a plain and an HTML version side by side. Attachments travel inside that text as base64 blocks, the reason an email with photos can weigh many megabytes.
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 stripped out. 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 render inside the message where the sender placed them. Every attached file shows as a chip under the subject and again in the Attachments tab, each carrying its size and a Save button. Files are decoded from their base64 form on your device and keep their original names. Attachments as .zip in the Download menu grabs all of them at once.
Newsletters and marketing mail often pull their pictures from the sender's server, and that request can double as a read receipt. The viewer keeps every remote picture unloaded and blocked, so opening an old email tells nobody anything. 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. Encoded subjects and file names are unpacked 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 and an attachment is decoded only when it is shown or saved. The memory in use tracks the single email on screen rather than the whole pile you picked.
An EML file is plain text, so opening it does not run any program on its own. The risk in email comes from what is inside a message: attachments you open afterward and links you click. 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. As with any email, treat attachments and links from a sender you do not know with care. Scan a saved attachment before you open it.
Yes. Select as many .eml files as you like, drop in a whole folder or pick a .zip archive 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 container called winmail.dat, in a Microsoft format named TNEF. The viewer shows the file and lets you save it, but does not unpack 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 binary 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 wrapped with a short length line and a small trailer that Apple adds. The viewer reads that wrapper, 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 a mailbox in disguise. Some export tools write many messages into a single file with the .eml extension, which really makes it an MBOX. 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.
