Convert MHT to HTML

Verified by Adam B.· reviewed by FE Editorial ·updated Jul 1, 2026
QUICK ANSWER
Is it possible to convert MHT to HTML?
Yes - MHT converts to HTML.

Both Google Chrome and Microsoft Edge open .mht files natively; press Ctrl+S and choose 'Webpage, Complete' to save an .html file and a companion folder with images, CSS, and scripts. Microsoft Word can also open .mht and save directly as .html. Keep the output file and its folder together - the HTML references the folder by relative path.

Why convert MHT to HTML?

An .mht file bundles HTML, images, and CSS into a single MIME-encoded archive that not every editor or web tool handles. Converting to plain .html makes the content editable in standard web editors, compatible with static site hosts, and viewable without a browser configured to open MHTML. The MHTML format (RFC 2557, 1999) encodes all resources as Base64, which browsers decode during the save.

How to convert MHT to HTML

Microsoft Word APP

Open the .mht in Word via File > Open, then use File > Save As and choose 'Web Page (.htm, .html)' or 'Web Page, Filtered'. Complex CSS layouts may not survive faithfully.

mht2htm APP

Open the .mht in mht2htm to extract it to a standard .html file and a resource folder.

Quality & what to watch

  • Keep the output .htm file and its companion resource folder together; the HTML references images and CSS by relative path to that folder.
  • Very complex CSS - especially older IE-era styles - may not render identically after extraction; scripts are preserved but may not work without their original server context.
  • The .mht and .mhtml extensions refer to the same format; Chrome and Edge open both identically.

Frequently asked questions

What is the difference between 'Webpage, Complete' and 'Webpage, Single File' in the save dialog?
'Webpage, Complete' saves an .htm file plus a resource folder (what you want); 'Webpage, Single File' saves another .mht archive.
Will embedded images be preserved?
Yes - images encoded as Base64 in the .mht are written to the companion resource folder and re-linked in the HTML.
Can I edit the resulting HTML in a standard editor?
Yes - the output is plain HTML that any text editor or web IDE can open and modify.
Does this work with `.mhtml` files?
Yes - .mht and .mhtml are two names for the same format; Chrome and Edge open both identically.
