01 About this tool

Why analyze EML files, and how

Why use an EML file analyzer?

EML files hold the full message. This tool doubles as an online EML viewer, reader and parser, so you can inspect them without Outlook or Thunderbird: read the body, trace headers (SPF, DKIM, Received), list attachments, and spot phishing signals - all in one place, useful for cybersecurity analysis and email debugging.

Features of the EML Analyzer

  • EML and Outlook .msg viewer with HTML and plain text preview
  • Header analysis: SPF, DKIM, DMARC results and delivery route
  • Attachments: MD5, SHA-1, SHA-256 and disguised file detection
  • QR code phishing (quishing) detection in images and PDFs
  • Phishing risk score with the signals behind it

02 EML viewer

Open and read EML files online

A free online EML viewer and decoder

Received an .eml or .msg attachment and have no mail client to open it? Drop it here to read it like in Outlook: sender, recipients, date, subject, the message body as text or as a rendered HTML preview, and the list of attachments. The analyzer decodes Base64 and quoted-printable parts and foreign character sets, so encoded messages become readable.

Safer than opening it in your mail client

The HTML preview runs in a sandbox: scripts do not run and remote images, including tracking pixels that would tell the sender you opened the message, are blocked. Nothing is uploaded: the file is parsed in your browser, which makes this EML scanner safe for confidential or suspicious messages.

03 FAQ
How do I open an EML file without Outlook?

You can open an EML file online using this tool without installing Outlook or any email client. Simply upload your file and view its content instantly.

Can I view or read an .eml file online?

Yes. This works as an online EML viewer, reader and opener: drag and drop or paste your .eml and the message, headers, and attachments appear instantly in your browser - no Outlook, Thunderbird, or install needed.

How do I check if an email is phishing or safe?

Drag and drop the .eml file: the analyzer shows the authentication results (SPF, DKIM), the real sender IP and mail servers from the Received headers, and extracts every link and attachment, so you can judge whether the message is phishing or safe.

How do I decode an EML file?

Drop it in the analyzer: it decodes the MIME parts for you (Base64, quoted-printable, character sets), shows the message as text and as a sandboxed HTML preview, and lists every attachment with its real file type and hashes.

Can I open Outlook .msg files too?

Yes. Outlook .msg files are converted in your browser and analyzed like an .eml: headers, body, attachments and links.

Does it detect QR code phishing?

Yes. QR codes in image attachments, inline images and the first pages of PDF attachments are decoded, and a QR code that hides a link is flagged as quishing, a common way to slip phishing past mail filters.

What is an EML file?

An EML file is a format used to store a complete email, including message content, attachments, and headers.

Is my file secure?

Yes, your file is processed directly in your browser and is not stored on any server.

Can I analyze suspicious emails?

Yes, this tool is useful for analyzing email headers and detecting phishing or spam attempts.

Which software uses EML files?

EML files are supported by email clients like Microsoft Outlook, Mozilla Thunderbird, and Windows Mail.
