Pst Viewer Pro will let you open Outlook PST files so you can search and export email, but that’s only part of the story.  It can also be used as the default Windows software for opening .MHT and .MHTML web archive files. While any web browser can open a single .MHT file if you click on it, where PST Viewer Pro adds value is by bringing its search, browse and conversion capabilities (including PDF) to MHT file management.

While MHT and EML files are very similar in their structure, MHT files are missing certain  email fields, such as the email address information of the sender and recipient, date, subject matter and the email header information.

Internet Explorer can create a MHT file from a HTML website. To do this, go to File>Save As>Web Archive.

The result will be a .mht file that when opened in a web browser will present the formatted text and graphic. The nice thing about MHT files is that the elements are all contained within the single MHT file. If you would save the web page a HTML file, then any graphics and other elements would be saved separately from the .HTML file, making more difficult to share.

FireFox browser can also save a website as a MHT file:
File>Save Page As…>Website, complete

In addition to helping you manage directories of MHTML files, Pst Viewer
Pro can also export your email to MHTML format. If you want to convert .eml to .mht, or .msg to .mht, or even a .pst file, Pst Viewer Pro is the tool for you.

How do I manage many MHT files?

While it’s easy to create MHT files, and easy to open them in a web browser, eventually you will need a more efficient way to manage them than just opening them one by one.

Pst Viewer Pro is an excellent answer for managing MHT files. Pst Viewer Pro will read a directory of hundreds or thousands of MHT or MHTML files so you can search, view, print, and even convert them to PDF and other formats.

How can I convert MHT files to PDF?

With Pst Viewer Pro, select the MHT files from the mail list that you want to export to PDF.  Notice that MHT files will not reveal an email address in the “TO” column. That’s because, of course, that a MHT file does not contain all of the fields that a EML email file does.

Click the Export button to launch Pst Viewer Pro’s Export Manager.  Select the destination format of PDF and then start the export process.  Your MHT files will now be converted into PDF format.  Any links that were clickable or hot in the MHT file will remain hot in the PDF file.   Some MHT files with heavy javascript may not convert perfectly, but most of the MHT files will appear exactly as they do in the web browser.
