MHTML Converter – Convert MHTML in Python

Use the MHTML Converter guides to convert MHTML in Python to PDF, XPS, DOCX, PNG, JPG, BMP, TIFF, or GIF. Open the MHTML source as a binary stream, create save options for the target format, and call Converter.convert_mhtml().

MHTML, also called MIME HTML, stores a web page and its handled resources as MIME parts in a single archive file. Both .mhtml and .mht extensions are commonly used. Converting an MHTML archive is useful when the captured page must be printed, edited, shared as an image, or processed by an application that does not use MHTML directly.

Aspose.HTML for Python via .NET provides convert_mhtml() overloads for fixed-layout documents, editable DOCX output, and raster images. Format-specific settings are represented by classes from the aspose.html.saving namespace.

How MHTML Conversion Works

1. Open the source MHTML file as a binary stream.
2. Create save options for the required output format, such as PdfSaveOptions, DocSaveOptions, XpsSaveOptions, or ImageSaveOptions.
3. Call Converter.convert_mhtml() with the stream, save options, and output path.

The following example converts MHTML to PDF with default save options:

# Convert MHTML to PDF in Python

import aspose.html.converters as conv
import aspose.html.saving as sav

# Open the MHTML file
with open("document.mht", "rb") as stream:

    # Configure PDF output
    options = sav.PdfSaveOptions()

    # Convert MHTML to PDF
    conv.Converter.convert_mhtml(stream, options, "document.pdf")

Open the format-specific guides below for custom page settings, image options, CSS processing, and output considerations.

Choose an MHTML Output Format

Output	Choose it when
PNG	You need lossless page images, sharp graphics, or transparent output.
PDF	You need one fixed-layout document for printing, sharing, or archiving.
JPG	You need smaller lossy page images and transparency is not required.
DOCX	You need editable output for a word-processing workflow.
XPS	You need a fixed-layout document for an XPS-based workflow.
BMP, TIFF, or GIF	You need a different raster format for imaging or integration requirements.
