How can I convert pdf to png high quality on windows 10?

One thing I've noticed is that the output quality often depends on whether the PDF contains vector graphics or scanned images. Simply converting the pages to PNG isn't always enough—choosing a higher DPI (300 or 600 DPI) can make a big difference, especially for text, diagrams, and technical documents. If privacy is important, I'd also lean toward using an offline desktop converter instead of an online service for sensitive PDFs.

I have a question for everyone here: Which desktop PDF-to-PNG converter has given you the best balance of image quality, speed, and batch conversion on Windows 10 or 11? I'd love to hear some real-world recommendations before choosing one.
