Why should I convert my Word document to PDF before sending it to clients or employers?

Word documents often display differently depending on the recipient’s installed fonts and software version. Converting to PDF locks in the layout, typography, and page breaks, ensuring your document looks identical on every screen.

Are tables, lists, and bold/italic text preserved in the PDF?

Yes. PixelKit cleanly maps Word document styling—including table borders, bullet points, font weights, and headings—into the compiled PDF document.

Are my confidential business proposals or personal files safe on PixelKit?

Yes, 100%. PixelKit operates with a strict zero-server privacy architecture. Your Word documents are parsed in your browser memory and never uploaded to any remote server.

Technical Architecture

OpenXML Unpacking & Clean Document Compilation

A `.docx` file is a ZIP archive containing XML documents (WordProcessingML), relationships, and embedded media. Converting it to PDF without installing heavyweight desktop software like Microsoft Office or LibreOffice is a significant engineering feat.

PixelKit uses Mammoth.js to unpack the OpenXML document tree directly inside your browser memory. Semantic elements (headings, bold, italics, tables, and lists) are translated into a standardized clean document DOM.

The DOM is then passed to our client-side document compiler, which paginates content according to standard ISO A4 or US Letter dimensions, applies configurable margins, and emits a clean, standardized PDF binary with zero server uploads.
