Are you looking for solutions to convert EML to HTML? Your endless search ends here! We will explore the best solutions for data conversion, along with the reasons for the same. Read this technical blog till the end to know everything!

Many email users prefer offline email accessibility rather than continuous internet dependence, due to many factors like web interactivity, data archiving, and others. That’s where the necessity of EML data transfer to HTML comes in. While the EML file format is used by email clients like Outlook, Thunderbird, and Apple Mail, the HTML format is used by all web browsers for webpage development and accessibility. Moreover, the HTML format helps even non-technical people develop simple web pages without worries.

Reasons for EML Email Format Conversion to HTML

There are many reasons for exporting EML data files to HTML format, and we will mention some of them:

  • Web Accessibility: As we mentioned above, many email users prefer offline email accessibility, and that’s where the HTML format shines. Since HTML is the primary website coding language for websites, EML users can access their emails on web browsers like Google Chrome, Mozilla Firefox, etc., without any complications and accessibility issues.
  • Sharing and Offline Viewing: Another reason to convert EML to HTML relates to email sharing and offline accessibility. Since HTML files don’t require any special email client for content access, many email users convert their EML file data to HTML for easy content sharing. Moreover, the HTML files don’t require internet connectivity to access the textual data, in contrast to the EML format, which requires a constant internet connection.
  • Email Data Archiving: The third reason for EML email format conversion to HTML is the comfort provided by HTML files when it comes to data archival and indexing for the long term, making them a great email archiving choice. On the other hand, the EML data file is tied to specific email clients (Outlook, Thunderbird, etc.), which may drop EML file accessibility in the future. Hence, it becomes necessary to convert EML email file data to HTML for future email accessibility without email client dependence.

These reasons justify the email data conversion and the following section mentions solutions for the same.

How to Convert EML to HTML? – Preferred Methods

Now that we know the reasons behind the EML email format conversion to HTML, we will explore the solutions for the data conversion in this section.

Manual EML Email Transfer to HTML

The manual solution for EML data migration to HTML involves using the Mozilla Thunderbird application for email data conversion. Here, we will explore two workarounds using the Thunderbird app.

#Workaround 1: Manually Save EML File
The first manual workaround involves converting the EML files stored locally on your computer with the help of the Thunderbird app and its “Save As” feature. The following points mention the entire data conversion process:

  • Go to the system folder with the EML files and select one.
  • Right-click on it, and select Thunderbird from the Open With menu.
  • Click on the More menu in the right corner and select Save As.
  • Select HTML from the Save As Type menu.
  • Finally, click the Save button to manually convert EML to HTML.
  • Repeat the same process with other EML files.

#Workaround 2: ImportExportToolsNG add-in
The second workaround involves using the ImportExportToolsNG add-in in the Thunderbird app for the EML email format conversion to HTML. Follow these steps for the data conversion process:

  • Open the Thunderbird application on your computer.
  • Now, add the ImportExportToolsNG add-in to the Thunderbird app.
  • Next, select the EML file folder and right-click on it.
  • Select the ImportExportToolsNG menu and click on the Export All Messages in Folder option.
  • Next, choose the HTML Format menu.
  • Then, select your preferred option – Messages and HTML Index; Messages with Attachments and Index; Messages and Index with Subfolders; or Messages, Index, and Attachments with Subfolders.
  • Select the desired folder and click the Select Folder button to convert EML files to HTML.
  • View the converted HTML files in the destination folder.

These workarounds to convert EML to HTML look simple but present certain drawbacks. The first workaround is time-consuming due to the lack of bulk EML data conversion. Both workarounds may experience formatting loss during the conversion process, and they also require mandatory Thunderbird app installation on your computer.
