What is an MHTML file?
An .MHTML file (MIME HTML) is a web page archive format. It combines standard web text with external resources like images, scripts, and stylesheets into one single file. This allows you to save a complete web page and view it offline without broken layouts or missing images.
How to open MHTML files?
You can open .MHTML files directly in popular web browsers. Modern browsers based on the Blink engine, such as Google Chrome and Microsoft Edge, support this format. Older applications like Internet Explorer or Microsoft Word can also open these archives.
Best practices and troubleshooting
Sometimes, a browser will fail to open an .MHTML file correctly due to modern security restrictions on local scripts. If you only need the text or images inside the file, you can often rename the file extension to .EML and open it in an email client, because they share a similar data structure. For long-term storage or easier sharing, you should convert your file to a more common format. We recommend converting .MHTML to standard .HTML or .PDF formats on convert.guru.

The viewer.online/mhtml platform can analyze .MHTML files to identify the exact format and creator software, inspect the file structure, extract readable text, and check whether an online preview is available. Because web archives can be generated by many different tools, we recommend using our platform to identify the actual format of your specific file.
Summary
The viewer.online/mhtml tool is incredibly useful for identifying, inspecting, and understanding .MHTML files. It allows you to examine saved web pages safely without installing software or dealing with browser compatibility problems.
