EML to PDF: How to Merge .EML Files into One PDF Document?

PDF Logo

Eml files are individual email files that have been saved outside of an email client. Thunderbird is a popular client that saves emails as .eml files. For a variety of reasons, it is sometimes convenient to convert .eml files to different formats, such as PDF.

PDF is well suited for Email storage if you use the correct software.

When converting eml to pdf, consider how you want to structure your project. Questions you should answer before starting:

How many .Eml files are you working with?
If you have thousands of .eml files, then you will need software that can automate the export.

Do you need to convert .eml files to a single PDF or to individual PDF files?
Sometimes its more convenient to combine the .eml files into a single large PDF file.

How should file attachments be handled?
When converting email to PDF, file attachments are too often an afterthought, when they should be the main focus of the project. Consider whether the file attachments should be placed inside the PDF file as separate files that can be later extracted, or whether they should be combined into the PDF document image, or simply ignored.

EML to PDF Export: Selecting the PDF Page Format

EML Viewer Pro is an email viewer for Outlook .eml files that can also bulk convert .eml emails into .pdf files. We received this comment from a reader today, and thought it would be useful to expand our answer into a blog post for everyone:

“In Europe we use A4 paper format. Can EML Viewer Pro support A4 formatting whilst exporting to PDF?”

The answer is yes. EML Viewer Pro does support A4 and many other common ISO page formats. Currently, the following page sizes are supported for PDF export:

  • North American Letter, Note and Legal
  • Eurpoean A0 through A10, including A4
  • B0 through B5
  • Arch A through E
  • Fisa
  • Half Letter
  • Ledger
  • Letter 11×17

If you don’t see your page format in the list above, you can select “Custom” and define your own page formatting.  EML Viewer Pro also supports landscape and portrait printing.

Here is how to set your preferred page formatting while converting EML files to PDF files with EML Viewer Pro.

First start EML Viewer Pro and then select the “Export Profile” that you want to change. In this demonstration I’ll choose “PDF – attachments embedded.”  I do this from main EML Viewer Pro toolbar.

Next, click the “Edit Profile” button, which I have highlighted in yellow in the above image to bring up the “Export Profile Editor.”

Set the default pdf eml export setings using the profile editor.

I’ve highlighted the fields where you will indicate the desired page size and the landscape mode.  When the changes have been made to your satisfaction, click “OK” to save your settings.

That’s all there is to it!  This export profile will now use A4 or any other page formatting or landscape setting you specified when you export EML files to PDF.
