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

PDF Logo

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.

What Are EML Files?

Files with the .eml extension are email files that store the content, headers, and pictures included in an email. They can also contain any email attachments, so the file size can be large.

In general, .eml files are created by Microsoft Outlook or other similar email programs when someone receives or saves an email. If someone has sent you a .eml file and you don’t have Outlook on your system, you can still open it through other programs, though.

You can easily open .eml files with Microsoft Outlook Express, Windows Mail, or Mozilla Thunderbird. On a Mac, Apple Mail is always included as a default program and will open .eml files, or the Microsoft program suite includes a version of Outlook that can open .eml files. Eml viewer software programs can process these files if its not desirable to install a full fledged email client application.

Another option for advanced users is to open the .eml files you receive with Internet Explorer, Opera, or another web browser. The compatibility varies depending on the browser software and version you have, the content of the email and so on, but if you’re desperate for another option, this might work. If you can’t figure out how to do this, you can change the file extension from .eml to .mht and it may work. EML and MHT files are very similar, except that MHT files do not have the email header information. For some people, understanding how to change a file extension may be difficult, and it may be impossible if you are operating from a Windows account without Administrator privileges.
 
While the average .eml file should be accessible through an e-mail application or web browser, if this doesn’t work you could try to email the sender of the .eml file and ask them to forward the original email to you as text instead.
If you have many .EML files that you need to search or process, you can try a .EML file viewer.  PST Viewer Pro is one such viewer that is able to work with many different file types such as .EML, .MSG, .PST, .OST and even .MHT files.  Click here for more information on PST Viewer Pro https://www.encryptomatic.com/emlviewer/ and to download a free trial.
