ToolsGrid's PDF Splitter operates via an in-browser parsing and selective stream extraction pipeline powered by Mozilla's pdf.js and pdf-lib. When you upload a document, pdf.js renders lightweight thumbnail canvas previews directly into the DOM so you can visually verify sheet numbers. Concurrently, pdf-lib parses the underlying document object model and catalog tree in local memory.
When you trigger an extraction or page deletion, the engine instantiates a clean, empty PDF structure. Rather than executing a lossy render-to-image loop, it copies only the selected page indices via PDFDocument.copyPages(). This operation carries over all associated page dictionaries, font descriptor tables, stream annotations, and vector paths without modifying the underlying data streams. The engine then synthesizes fresh cross-reference (xref) tables conforming to ISO 32000 standards and exports the resulting Uint8Array directly to your local file system. Because all processing executes in client memory, confidential records remain on your local device, and memory buffers are immediately deallocated when you close the tab.
