PNG is the format you want when image fidelity matters. It uses lossless compression (no JPEG-style artefacts around text or sharp edges) and supports transparency, which JPG can't. Common use cases: pulling a logo or icon out of a brand PDF, exporting a screenshot of a product spec for documentation, or producing high-quality slide imagery from a PDF deck.
PDFly renders each page in your browser using pdfjs, then exports via canvas.toBlob — the same lossless pipeline browsers use natively. The output file size is larger than JPG (typically 2-3× for the same page) but the quality is pristine.
