Theme-Based Formatting
Word document themes (colors, fonts, effects) applied via styles are reproduced correctly.
Convert any DOCX file to PDF with full support for custom styles, embedded fonts, linked images, and complex page layouts. Free, instant, no account needed.

DOCX uses a different internal structure than DOC - and requires a converter that understands the difference.
DOC is the binary format used by older Word versions. DOCX (introduced in Word 2007) uses an XML-based Open Document format. DOCX supports a wider range of features: theme-based formatting, content controls, SmartArt, advanced table styles, and structured document parts.
When converting DOCX specifically, it's important that the converter interprets the XML structure correctly - not just renders a screen preview. iMZi PDF processes DOCX files at the specification level, producing accurate PDF output regardless of which DOCX features your document uses.
Simple process, accurate output for all DOCX file types.

Every DOCX feature you use is handled in the PDF.
Word document themes (colors, fonts, effects) applied via styles are reproduced correctly.
Heading 1, Heading 2, and all custom paragraph styles are converted with correct visual hierarchy.
Text boxes, date pickers, and dropdown content controls from Word forms appear as static content in the PDF.
Word's built-in and custom table styles with conditional formatting are rendered accurately.
Footnote and endnote references and content are preserved in the correct positions in the PDF.
Internal cross-references (e.g., "See Section 3.2") maintain their accuracy in the output PDF.
Older PDF converters were built for the DOC format and do not fully support the DOCX specification. If you've ever had a DOCX convert with slightly wrong formatting - a shifted table, a different font, a missing image - it is likely because the converter did not fully support Open XML. iMZi PDF is built for the modern DOCX format and handles all its features correctly.
All modern Word documents are DOCX - these are the most common conversion needs.
