MHTML to HTML converter

MHTML is a web archive format rather than an ordinary HTML page. A saved archive can contain a main document, stylesheets, images and fonts inside a multipart MIME container. Renaming its extension to HTML does not unpack those parts. This converter reads the archive locally, decodes its supported resources and builds an HTML document that can be downloaded or published.

Choose a file ending in MHTML or MHT. Both names refer to the same kind of archive. The tool handles base64 and quoted-printable transfer encodings and uses the declared character set for text. Saved image and font resources become data URLs inside the resulting page. Stylesheets are rewritten to use archived assets where possible, so a successful conversion can travel as a single HTML file.

A browser archive is still a snapshot. Scripts, frames and other active resources are removed from this static conversion. Resources that were never captured cannot be recreated. The tool reports missing resources instead of silently fetching the original site, and removes unsupported responsive alternatives so you can review the main image. Links in the document can still point to the original website; review them before sharing.

After conversion, compare the preview with the content you intended to preserve. You can edit the HTML source, download a local copy, or open the DocHost publisher with the converted document already filled in. Publishing creates a separate hosted page with its own access and expiry settings. It does not restore the original website, its sign-in session or its interactive application behavior.

An analyst saves a supplier specification page from a desktop browser. The saved file is an MHT archive containing the article, a stylesheet and two product images. A colleague on another device cannot conveniently open the archive, so the analyst chooses it in this tool.

The converter finds the main HTML part and decodes the archived images. The preview shows the specification text with its headings and the captured product photograph. One badge was loaded after the browser made the archive and is absent from the file. A warning prompts the analyst to check the missing resource instead of assuming the entire original page was captured.

The analyst removes a navigation block that is no longer useful and reads through the tables at mobile width. The resulting HTML is downloaded as a backup. To share the readable specification, the analyst selects Publish converted HTML, checks the available access options and creates a DocHost link. The colleague can open that webpage without an archive viewer. If the analyst also needs a printable copy for a meeting, the related HTML to PDF tool can print the converted HTML. None of these steps recreates the supplier’s shopping cart or account controls; the shared document is a static reference snapshot.
