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.

How to Batch Print .EML Files

Printing .EML files can be a very tedious chore. If you are using an email client like Outlook or Thunderbird to open individual .eml files and print them, it gets boring fast.  Opening and printing .eml files this way is ok if you only have a few, but what if you have a folder filled with hundreds or thousands of .eml files?

EmlViewer Pro (also known as PstViewer Pro) is a Windows software application that helps you work with email content.

EmlViewer Pro lets you to batch-print any number of selected EML files. Here’s how to do it.

First, start EML Viewer Pro. Using the folder explorer, select the folder containing the .eml emails. The messages will quickly populate the software’s Mail List.

Next, type “Control-A” to select all of the emails in the list.  Selected emails will appear blue.

EML Viewer Pro will start printing your emails. You can go have some coffee while it’s printing. That’s all there is to it.

If you can send .eml files to a printer, can you also batch print .eml files to a PDF file?

Yes, you certainly can! One options would be to tell EML Viewer Pro to print to a virtual PDF printer, such as the free BullZip virtual PDF printer.  Virtual printers may each behave a bit differently, so you should be aware of any peculiarities with your chosen software.

If you want to print multiple .eml files to a single PDF, make sure your virtual printer will support that. Many virtual PDF printers will print separate PDF files, but some will create a single .pdf file. Snaggit is a software tool with a virtual printer that will accept the export of many .eml files and combine them into a single file which can later be converted to PDF.

EML Viewer Procan also prints .eml files directly to PDF files. Here are a couple of articles we wrote earlier specifically about how to print .eml files to PDF files.
