What actually causes formatting to break during conversion
Three things account for most bad PDF-to-Word conversions: reading text in the wrong order (common with multi-column layouts), treating tables as unstructured text instead of detecting rows and columns, and dropping font information so the output falls back to a generic default typeface.
How PrivaPDF avoids each one
The converter analyzes the geometric position of every text run on the page before deciding what order to place it in the output document, which keeps multi-column academic papers and brochures from interleaving incorrectly. Table regions are detected from aligned text and ruling lines and rebuilt as genuine Word table objects. Where the original font can be embedded, it's carried over; where it can't (some commercial fonts restrict embedding), the closest available system font is substituted rather than defaulting to something unrelated.
Complex, heavily designed documents — multi-column magazine layouts, documents with text wrapping around images — still sometimes need light manual cleanup afterward. That's true of every PDF-to-Word tool, including paid desktop software.
