How to Archive .EML Emails as PNG Image Files

Files with the .eml extension are RFC-822 formatted email messages. EML Viewer Pro is a tool for managing eml files, and converting them to different formats, including image files like PNG, GIF, TIF and BMP. 


Today’s tutorial will show you how to use EML Viewer Pro to convert a html email message into a PNG file.  Download and install the 15 day free trial of EML Viewer Pro so you can follow along.

EML Viewer Pro can display your .eml and .msg email files in a list.  It’s easy to scroll through this list and browse your emails. You can also search your emails and display those that meet your specified criteria, such as a date range, from a certain sender, or emails that match a search query.

In our example, I have a html formatted .eml file that contains an advertisement from a computer sales company. Selecting the message from EML Viewer Pro’s message list causes the email to display.

To export this message to PNG format, I simply select the PNG export file from the drop down list in the toolbar. It is possible to select many .eml files for conversion (type Ctrol-A to select all emails in the list).  To start the export operation from eml to png, I click the export button.

The export button is the green down arrow that points to a yellow stack of paper (I drew a red arrow pointing to it in the above image).

The export operation will begin, and the email is formatted into a png file. The size of the png image file will vary with the length of the email.  In this example, you can see that the resulting PNG is quite long.  EML Viewer Pro has preserved the images and html formatting. The email header information is included in the top of the image.

Converting EML email files to PNG or other images are a good way to preserve emails for sharing or archiving. Because many html formatted emails have images that are hosted remotely, the contents of the email are not downloaded until the email is displayed. Saving the html email as a png file preserves a copy of the original message, and is not dependent upon the availability of a remote server.


EML Viewer Pro is a versatile tool that helps you transform your emails into many different formats. In addition to PNG, you can also format emails to pdf, csv (Excel), html, mhtml, and others. Download a free trial today and see what EML Viewer Pro can do for you.

MSG to EML: How to Convert Outlook Email from Outlook .MSG to .EML

There are two basic formats for storing individual email messages: .eml and .msg

The .eml open message standard was pioneered by a document called RFC-822 which set the convention for creating and formatting email messages.

Microsoft, however, decided to pursue a different path.  Outlook email messages have the file extention .msg, and are not compatible with email clients like Thunderbird that open .eml files.  Microsoft Outlook can open both .msg and .eml files.

Converting Outlook .Msg emails into .Eml files ensures that the emails are accessible in an open messaging standard, which makes email more suitable for long term storing or archiving.  There are also different situations where importing email requires conversion of email from .msg to .eml.

There are various tools on the market that can accomplish this. The two tools we will look at today are developed by Encryptomatic LLC.

MessageExport for Outlook

MessageExport is an Outlook add-in.  If you already are using Outlook, MessageExport will let you save emails directly from Outlook to .eml format, as well as PDF and many other formats.

MessageExport supports Outlook 2016/2013/2010 and 2007. After installation, it becomes part of the Outlook toolbar.   Using MessageExport is as simple as selecting one or more emails from the mail list, choosing “Export to EML” from the Outlook toolbar, and clicking on the “Export” button.

PstViewer Pro Eml Viewer

PstViewer Pro (formerly called EmlViewer Pro) is an email viewer that reads .eml, .msg, .pst, .ost and other popular email file formats.

To convert .Msg to .Eml with PstViewer Pro, first select the Windows folder containing the .msg files.  Next, highlight the .msg files in the mail list that you want to convert to to .eml
Finally, select “Export to Eml” from the drop down list and click “Export.”

PstViewer Pro will then convert the msg files into eml files. Because PstViewer Pro supports many other formats, you can mix and match between them to accomplish a wide range of email conversion tasks.
