No upload. libheif decodes each Primary Image and WebAssembly creates the PDF inside one background Worker.

Private PDF assembly

Worker isolated

Image buffers move to a background Worker so PDF generation does not lock the page.

WASM XObjects

libheif normalizes each Primary Image to JPEG, then the engine embeds it as a PDF Image XObject.
