Why is PNG better than JPG for text and diagrams?

PNG uses lossless compression, meaning no visual information is lost during conversion. This preserves the sharp edges of text characters, thin lines in diagrams, and fine details that JPG compression might blur. If your PDF contains mostly text, tables, or technical drawings, PNG will produce noticeably cleaner results.

Do PNG images from PDF conversion support transparency?

The PNG images produced by this tool have a white background matching the original PDF page rendering. If your PDF has transparent elements, they will be composited against a white background in the output PNG. The PNG format itself supports transparency, but PDF pages are rendered as opaque images.

Why are PNG files larger than JPG?

PNG uses lossless compression, which preserves every pixel exactly. This results in larger files compared to JPG, which discards some visual data to achieve smaller sizes. For a typical document page at 150 DPI, expect PNG files to be 2 to 5 times larger than JPG. At 300 DPI, PNG files can be several megabytes per page.

What DPI should I use for PNG output?

For on-screen use (presentations, websites, email), 150 DPI provides crisp results with reasonable file sizes. For printing or archival, 300 DPI captures maximum detail. 72 DPI is fine for quick thumbnails or previews where file size matters more than quality.

Can I convert a large PDF with many pages to PNG?

Yes. The converter handles multi-page PDFs and produces one PNG per page. For very large documents (50+ pages at 300 DPI), the process may take a moment since PNG files are larger. You can download all pages at once as a ZIP archive.
