Understanding pdf to png

PNG is lossless, which makes it the right choice whenever the page contains text, tables, diagrams or screenshots. Every pixel comes out exactly as rendered, with no compression artefacts around glyph edges.

The cost is size: a 300 DPI PNG of an A4 page can easily exceed 5 MB where the JPEG equivalent is a few hundred kilobytes. Choose PNG when fidelity matters and JPG when weight matters.

Rendering happens locally with pdf.js, so even confidential pages never leave the browser.

When you would use it

  • —Extracting a chart or diagram from a report for reuse in a presentation.
  • —Producing crisp page images for documentation.
  • —Capturing a page for pixel-accurate design review.
  • —Preparing page images that will later be OCR'd.

Practical tips

  • Render at 300 DPI when the image will be printed, 150 DPI when it will only be viewed.
  • PNG's lossless nature makes it the best input for OCR — artefacts hurt recognition accuracy.
  • For photographic pages, JPG will be a fraction of the size at the same perceived quality.

Troubleshooting

The browser runs out of memory
High DPI on many pages is demanding. Export a page range at a time.
Files are very large
That is inherent to lossless encoding; use PDF to JPG if size is the constraint.
