Why doesn't complex formatting convert perfectly?

Browser-based DOCX to PDF conversion extracts content using mammoth.js, then re-renders it using jsPDF. This process cannot perfectly replicate complex Word features like custom fonts, multi-column layouts, embedded charts, or advanced table styles.

Why does it say my .doc file isn't supported?

Legacy .doc files (Word 97-2003 format) use a binary format that mammoth.js cannot read. Only .docx files, which use the OpenDocument XML format, are supported. You can convert a .doc to .docx in LibreOffice or Google Docs.

Is my document uploaded to a server?

No. DOCX parsing and PDF generation both happen in your browser. Your document never leaves your device.

Can I convert multiple DOCX files at once?

Currently, the tool converts one file at a time. Upload your files one by one if you have multiple documents to convert.
