Free online MHT to PDF converter

Source format: MHT

MHT is a web archive format, also known as MHTML or .mht/.mhtml. It stores a web page and its resources, such as HTML, images, and stylesheets, in a single file using MIME encoding. This format was commonly used by Internet Explorer and is still supported in some browsers and desktop applications for offline viewing or preserving a page as it appeared at a specific moment.

MHT is useful when you want one portable file instead of a page folder full of separate assets.

Target format: PDF

PDF is a fixed-layout document format designed for consistent viewing, printing, and sharing across devices. It is widely supported and well suited for archiving, reports, forms, manuals, and other documents that should keep the same appearance everywhere.

Converting MHT to PDF is a practical way to turn a saved web page into a more universal, print-friendly file.

How to convert MHT to PDF

Best desktop method: open the file in a browser and print to PDF

If your system can open the .mht file in a browser, printing to PDF is usually the most reliable option:

1. Open the .mht file in Microsoft Edge, Internet Explorer, or another app that supports MHT.
2. Check that the page displays correctly, including images and formatting.
3. Choose File → Print or press Ctrl+P.
4. Select Microsoft Print to PDF or another PDF printer.
5. Adjust layout, margins, orientation, and scaling if needed.
6. Click Print, choose a filename, and save the output as .pdf.

Alternative desktop method: LibreOffice

Some MHT files can be opened in LibreOffice Writer or imported through a supported workflow, then exported to PDF:

1. Open the MHT file in LibreOffice if your version supports it.
2. Review the layout and embedded content.
3. Use File → Export As → Export as PDF.
4. Save the resulting .pdf.

Command-line option: LibreOffice headless conversion

If LibreOffice opens the file correctly on your system, you can try batch conversion with:

soffice --headless --convert-to pdf input.mht

Important: support for MHT input varies by LibreOffice version and platform, so this method may not work for every file.

Online converters

Some online file-conversion services support MHT to PDF. Upload the .mht file, choose PDF as the output format, and download the converted file. Use caution with private or sensitive content, since online tools require uploading your file to a third party.

Quality and compatibility notes

Rendering quality depends on the converter. Because MHT files can contain complex HTML, fonts, scripts, and embedded resources, the resulting PDF may not match the original page exactly. Browser printing usually gives the best visual fidelity for modern pages.

Interactive content is usually flattened. Forms, animations, scripts, and dynamic behavior typically do not remain interactive in PDF.

Page breaks and scaling may need adjustment. Long pages can span multiple PDF pages, and print settings such as margins, orientation, and scaling can affect readability.

Not every app opens MHT files. If one program fails, try another supported browser or a dedicated converter. For most users, printing from a browser to a PDF printer is the simplest and most dependable approach.
