How to Convert Multiple .EML Emails Into A Single PDF File

EMLViewer Pro is a Windows software tool for managing and converting .eml files. One of its core capabilities is converting from .eml to .pdf format.  Some of our earlier articles have focused on this capability in detail, and today we’re going to focus specifically on creating a single pdf file that contains multiple .eml email files.

When converting many .eml’s into one .pdf, you’ll need remember that the resulting PDF can get quite large. Be sure that you have plenty of space available on your hard drive.

The first step in our process is to start EmlViewer Pro, or it’s twin, PstViewer Pro. Since the two software packages have merged, they now contain identical capabilities to manage .eml.  You can download a free trial of EmlViewer Pro here and follow along.

From the folder navigation on the left side of the EmlViewer Pro interface, clck on the folder containing your .eml files.  EmlViewer Pro will then load the emails into a list, where you can sort or search for the messages you want to convert to pdf.

Now tell EmlViewer Pro which emails you want to move into a single PDF file. You can select individual emails from the list. To select them all, click on the first one in your list and then do a CTRL-A on your keyboard to select all of the messages. When a message is selected, it will have a blue highlight.

The last step is to tell EmlViewer Pro which profile to use by selecting it from the drop down list on the Export tab in the main toolbar. There are 3 options provided for exporting .eml into a single .pdf:

Single PDF – attachments embedded. This option includes email file attachments as separate files within the .pdf. They can extracted later from the PDF using PDF viewing software.

Single PDF – attachments saved to disk.  Converts .eml files into a single PDF, but attachments are saved to your hard drive, outside of the PDF.

Single PDF – attachments converted/included.  EmlViewer Pro attempts to convert the attachments into images that are displayed within the PDF file. It can convert many of the most common and popular image and document files. If it is unable to convert a file, then it defaults to embed the file within the PDF.

By now, you have selected your emails and chosen the best export profile for your project.  All that’s left to do is click the “Export” button and start the  conversion operation. EmlViewer Pro may prompt you to choose a file name for the .PDF file.

The amount of time it takes to convert the .eml files to .pdf will vary by the number of emails you need to convert, the size of the emails, file attachment sizes and types, and whether the .eml files have embedded graphics. If the image files are hosted on a server, EmlViewer Pro will attempt to download them and render the email.  All of these factors will impact how quickly the operation will complete.

The converted eml emails will appear in the .pdf with the traditional header information at the top of each email, which includes From, Sent Date, To, Subject, and any file attachments.

How To Convert .EML Email Files Into .PDF Files?

.EML files are email files. They contain the email message and any file attachments that were included with the message.  If you find yourself with a batch of .eml files that you need to convert into .PDF files, EML Viewer Pro can help you.

Why would someone ever have .eml files? There are many situations where you may encounter them.  As a published open standard (RFC-822) .eml files are used by many different email clients, including Windows Mail, Outlook Express, Thunderbird, and others.  If you are involved in a court case, or received a FOIA request fulfillment from a government agency, you may have received the emails in .eml format. 

Converting .eml emails into common .pdf files sounds like it should be a very simple thing to do; and if you have the correct software, it is simple.  Many people encounter problems by attempting eml to pdf conversion using software that is not designed for that purpose.  For example, a free .pdf printer app might do a great job rendering the email message as a .pdf file, but may fail to convert file attachments.  Specialized needs, such as adding an email individually to an existing .pdf file, or embedding file attachments inside the pdf may not be supported. What if you need to convert thousands of .eml files to individual pdf files, and apply a specific naming structure to the files?  No free app that we’re aware of can support these complex operations.
