Common Split Use Cases

"Needed to extract just one chapter from a 500-page PDF. The bookmark split worked perfectly - each chapter became its own file in seconds."

Code for page extraction:

// Extract pages by range
const pdfDoc = await PDFLib.load(fileData);
const pages = pdfDoc.getPages();

// Extract specific pages
const newPdf = await PDFLib.createDocument();
const pageIndices = [0, 2, 3, 4]; // 1st, 3rd, 4th, 5th pages

for (const idx of pageIndices) {
  const [page] = newPdf.copyPages(pdfDoc, [idx]);
  newPdf.addPage(page);
}

await newPdf.save();
