Word to PDF Formatting: What Is and Isn’t Preserved
Word to PDF rebuilds your document from scratch as a real, text-based PDF rather than taking a picture of each page. That approach keeps the output text selectable and searchable, but it means formatting fidelity is best-effort rather than pixel-perfect. This guide explains what is preserved and what commonly does not match exactly.

What is preserved
- Headings (levels 1–6), mapped to proportionally sized text.
- Paragraphs, with word-wrapping and pagination.
- Bold and italic text.
- Numbered and bulleted lists.
- Simple tables, with each cell wrapped and drawn in a grid.
- Embedded JPG and PNG images, scaled to fit the page.
What is best-effort or unsupported
Because the PDF is rebuilt from the document’s structure rather than rendered pixel-for-pixel like Word’s own PDF export, a few things do not carry over exactly.
- Exact custom fonts are not embedded — text is drawn with standard PDF fonts.
- Multi-column layouts and precise text positioning are not replicated.
- Complex or deeply nested tables may not match the original column widths.
- Image formats other than JPG and PNG (for example WMF or BMP) are replaced with a small "[image not supported]" note rather than failing the whole conversion.
- Underline formatting and text color are not currently carried over.
Why this trade-off
The alternative — rendering the document to images and stitching them into a PDF — would preserve visual layout more closely, but the resulting PDF text would not be selectable, searchable, or copyable, and files would be larger. Word to PDF prioritizes a normal, usable PDF over pixel-perfect visual matching.
Word to PDF Formatting Limits FAQ
- Does the PDF keep my exact fonts?
- No. Text is drawn using standard PDF fonts rather than embedding your document’s original fonts.
- Are tables preserved?
- Simple tables are drawn as a grid with wrapped cell text. Complex or deeply nested tables may not match the original column widths exactly.
- Why isn’t the PDF pixel-identical to Word?
- The PDF is rebuilt from the document’s structure so the output text stays selectable and searchable, rather than rendered as an image of each page.
- What happens to unsupported image formats?
- Images that aren’t JPG or PNG are replaced with a small "[image not supported]" note so the rest of the conversion still completes.
- Is underline or text color preserved?
- Not currently — only bold and italic formatting carry over.
