Frequently Asked Questions
Why do Word files look different on Mac and Windows?
Microsoft Word relies on fonts and printer drivers installed on the local operating system. If a font is missing, Word substitutes it, causing line shifts. PDF avoids this by embedding fonts directly.
Can I convert Word to PDF without Microsoft Office installed?
Yes. SmartAssPDF converts DOCX files directly in the browser via open-source Apache POI and PDFBox engines.
