Implementation Guide & Technical Reference
Embedding Images via pdf-lib
const pdfDoc = await PDFLib.PDFDocument.create();
for (const imgFile of images) {
const bytes = await imgFile.arrayBuffer();
const img = imgFile.type === 'image/png' ? await pdfDoc.embedPng(bytes) : await pdfDoc.embedJpg(bytes);
const page = pdfDoc.addPage([img.width, img.height]);
page.drawImage(img, { x: 0, y: 0, width: img.width, height: img.height });
}Lossless in-memory image embedding.
Frequently Asked Questions (FAQ)
Can I mix different image formats (e.g. JPG and PNG) in one PDF?
Yes. You can combine JPG, PNG, WebP, BMP, and SVG files seamlessly into a single unified PDF.
Will my image resolution be compressed or degraded?
By default, images are embedded at their native resolution without lossy recompression. You can also select compression presets if you need a smaller file size.
Can I reorder images before generating the PDF?
Yes. The interactive preview grid allows drag-and-drop reordering of all thumbnails prior to export.
Is there a limit on how many photos I can combine?
There are no artificial limits. You can combine 50+ images smoothly in modern browsers.
