Short, plain answers about turning PDF pages into PNG images in the browser: choosing pages, 96, 150 or 300 dpi, several pages in a ZIP, file size, lossless encoding and the white background.

• How to convert PDF pages to PNG

  Open a PDF, keep the pages you need, pick 96, 150 or 300 dpi and save them as PNG images — one page or many, on a computer or a phone, with no upload.

• Choosing a resolution for PDF to PNG: 96, 150 or 300 dpi

  How many pixels a PDF page gets at 96, 150 and 300 dpi, why PNG files grow fast at high resolution, and what happens when a very large page is scaled down.

• Saving several PDF pages as PNG images

  Pick scattered pages or ranges from a PDF, save them as PNG images in document order, and find them in one ZIP. How file names work and how to open the ZIP.

• PNG file size and what “lossless” means

  Why a PNG made from a PDF page can be small for text and very large for photos, what lossless encoding does and does not mean, and how resolution changes the size.

• What changes when a PDF page becomes a PNG

  Why a PNG made from a PDF page has a white background instead of transparency, and what happens to text, links, form fields, signatures and document structure.
