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.

An EML file is a common file format produced by email client software for storing individual email messages.
