No upload. WebAssembly creates the PDF inside a background Worker, then returns a local Blob URL.

Private PDF assembly

Worker isolated

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

WASM XObjects

The engine decodes each image and embeds it as a PDF Image XObject with page-fit placement.

The browser rejects more than 30 files, 50MB per file, or 150MB total before conversion.
