WebAssembly PDF Pipeline

How document streams are manipulated locally inside WebAssembly memory:

// 1. Read binary PDF stream into Uint8Array
const fileBuffer = await file.arrayBuffer();

// 2. Load PDF into local WASM engine
const pdfDoc = await PDFDocument.load(fileBuffer);

// 3. Perform in-memory manipulation and serialize
const outputBytes = await pdfDoc.save();
triggerLocalFileDownload(outputBytes, "processed-document.pdf");
