Secure PowerPoint to PDF: Convert Presentations Locally in Your Browser

Presentation decks are the core of corporate updates, business ideas, and personal projects. Uploading raw PPTX archives to public converters poses significant compliance and privacy concerns. Document Alter solves this by unpacking slide archives directly inside your browser memory context.

Client-Side Slide Decompression and XML Parsing

The tool parses the compressed OpenXML zip container (.pptx) using JSZip. It systematically maps slide paths (ppt/slides/slide*.xml) and extracts the semantic hierarchy of shapes and texts (<a:t>). The parsed data is structured dynamically onto vector slides and outputted as landscape PDF documents using jsPDF.
