Copies original PDF object streams without rasterization, preserving vector text and sharpness.
All page array operations execute inside client browser memory. Zero files leave your device.
PDF document structure stores page references inside the root catalog's /Pages tree node within the /Kids array. Reordering pages modifies the child indirect object reference order without rewriting underlying page content streams.
Using newDoc.copyPages(srcDoc, pageIndices), pdf-lib copies indirect page references based on 0-indexed integer arrays, enabling rapid sequence reorganization and page duplication.
Because page stream bytes are transferred directly between PDF document objects in client browser memory, rendering zero-copy output avoids image re-compression or font corruption.
