🔍 The Problem It Solves

Organizations often share PowerPoint presentations, Word documents, and PDFs in SharePoint, Microsoft Teams, or OneDrive with "Block Download" or "View-Only" permissions enabled.

Because these viewers render each page onto an HTML5 <canvas> element inside an iframe, standard browser print dialogs (Ctrl+P) and traditional web extensions fail, resulting in completely blank pages.

DocSnapper runs client-side inside the active page context, captures rendered canvas frames page-by-page at native resolution, and compiles them into a clean, printable multi-page PDF.
