One .pst file can contain many e-mails. .Eml files are individual e-mails formatted in an open specification (RFC-822).

How to Convert EML Emails to GIF Files

EML files are a type of format that email clients, such as Microsoft Live Mail and Outlook Express, uses to save individual email messages. The file extension itself is a standard known as RFC-822.

Many different pieces of information, including e-mail messages, file attachments, internet header information, html formatting and more can be stored within this specific file type. Usually, EML files are opened individually. Click on an .eml file and it will likely open in your default email client. However, if you want to be able to manage and search a quantity of .eml files, then you should take a look an email viewer like EML Viewer Pro.
EML Viewer Pro is a fully capable e-mail reader that allows you to take complete control over your Microsoft Outlook EML files. It also opens Outlook PST, OST and MSG files. You don’t even need to have Microsoft Outlook installed on your computer to work with any of these types of files.

With EML Viewer Pro you can export an Outlook EML file into a variety of different formats, including the popular GIF image file format. Exporting from the EML to GIF file format allows you to take a file that was previously only usable with a handful of specific programs and store it as a static image that you can be opened on virtually any computer or device.
