📝 Text — crisp, anti-aliased text at any size
📊 Charts and diagrams — perfect edges, no compression artifacts
🖥️ Slides and presentations — exact colour reproduction
📐 Technical drawings — fine lines with no blurring
🔗 Images for web — perfect for embedding in web pages

Frequently Asked Questions

Is the PNG output truly lossless?

Yes. The PDF page is rendered pixel-by-pixel onto an HTML5 Canvas using pdf.js, then exported as PNG using lossless compression. There is no quality loss — the output is a faithful pixel-perfect representation of the PDF page at the chosen scale.

What resolution should I choose for PNG output?

2× (the default) produces images at approximately 144 DPI — sharp and suitable for screen use and most web purposes. Choose 3× or 4× for print-quality PNGs where fine text or fine detail must be preserved at larger physical sizes. Higher scale = larger file size.

Does this work with scanned PDF documents?

Yes. Scanned PDFs contain embedded image data that pdf.js renders faithfully. The output PNG will be as sharp as the original scan resolution allows. Note: scanning at higher DPI before creating the PDF will yield better PNG output quality.
