About TNEF files

TNEF (Transport Neutral Encapsulation Format) is a proprietary file format used by Microsoft Outlook and Exchange to package attachments in emails. It is also known as winmail.dat, and it is used to store files, folders, and other data. TNEF files are not supported by many email programs, and they can be difficult to open.

TNEF files can be converted to other file formats using software such as TNEF's Enough or various tools. These programs can extract the attachments from the TNEF file and save them in a format that can be opened by other programs.

When converting TNEF files, it is important to consider the type of file that is being converted. Some file types, such as images, can be converted easily, while other types, such as spreadsheets, may require additional software to open the converted file. Additionally, some TNEF files may contain malicious code, so it is important to be cautious when opening them.

Using TNEF files can be difficult and time-consuming, and it is often better to use a free and easy online website such as Convert.Guru to convert TNEF files. This website allows users to quickly and easily convert TNEF files to a variety of formats, including PDF, HTML, JPG, and more.


The TNEF Converter Story

The history of Convert.Guru began more than 25 years ago in California, when Tom Simondi published the most comprehensive database of file formats on his website. Before that, Tom had worked on Space Shuttle development at the Air Force Systems Command’s Space Division in Los Angeles. He is known as one of the top programmers of the late 1980s.

When Microsoft integrated Tom’s Filext database into Windows XP, it became the leading platform for analyzing and processing file types and formats.

Today, we use the latest technologies to analyze, process, and convert one of the world's largest collections of file formats. We are committed to developing the best TNEF converter by continuously improving quality, usability, and reliability.
