Technical Architecture of Client-Side PPTX to PDF Conversion
PowerPoint files (`.pptx`) are structured OpenXML archives containing XML markup, embedded vector graphics, typography references, and slide layout definitions. Our converter unpacks these compressed XML structures client-side, maps slide relationship definitions (`.rels`), extracts embedded image assets from `ppt/media/`, parses table structures (<a:tbl>), and compiles them into pristine PDF slides using high-resolution browser canvas graphics.
By executing the entire extraction and vector compilation process directly within your browser memory sandbox, sensitive enterprise presentations, financial slides, and proprietary deck materials remain 100% confidential without ever touching external cloud servers.

Frequently Asked Questions
Are embedded images and tables included in the converted PDF?
Yes. The parser maps slide relationships and extracts embedded media from ppt/media/ as well as table elements (<a:tbl>), ensuring charts, graphics, and tables are preserved in the output PDF.
Are legacy binary .ppt files supported by this client-side converter?
Legacy .ppt files use a proprietary binary structure that cannot be decompressed client-side in pure browser JavaScript. To convert a .ppt file, save or export it as .pptx in PowerPoint or Google Slides first.
Is my presentation uploaded to any remote server during conversion?
No. All slide extraction, OpenXML parsing, and PDF rendering take place 100% locally within your browser memory.
