Convert PDF pages into crisp PNGs. For text-heavy documents PNG stays sharper than JPG.
Pages of text, tables, charts and line drawings are made of hard edges on a plain background. PNG is lossless, so those edges stay exactly as the renderer drew them, with none of the faint smudging JPG compression can leave around letters. That makes PNG the better choice for a page you want to paste into a slide, attach to a ticket, annotate in an image editor or quote in a report. For pages that are mainly photographs, JPG gives much smaller files with little visible difference.
The PDF is opened with pdf.js, Mozilla's open-source renderer, which is downloaded from a public CDN the first time you add a PDF. Each page is drawn at twice its nominal size, roughly 144 dpi, on a white background; very large pages are scaled down so each stays under about 25 megapixels. Up to 100 pages are unfolded per document, and each page becomes its own file named after the PDF with its page number. PDFs that need a password to open cannot be read.
When writing a PNG, this tool also tries a palette version — up to 256 colours at Recommended and High, 128 at Smaller, 64 below 60 on the slider — and keeps it only when it is smaller than the full-colour PNG. A typical text page is mostly white, black and the grey shades of smoothed letters, so it often fits within the palette exactly and nothing is lost. Pages with photographs or colour gradients may be colour-reduced with dithering when that saves space. Choose High if you want the most faithful result.
Everything runs inside your browser. Because the image never reaches a server, we cannot store it or look at it. That difference matters when the file is company material or a personal photo.
