About this PDF to PNG converter

PDF to PNG renders each page of your PDF as a lossless PNG image. Because PNG doesn't introduce compression artefacts, it is the right choice for pages with fine text, tables, charts or diagrams that need to stay perfectly crisp. The PDF is processed on your device and never leaves it.

How PDF to PNG conversion works

  1. PDF.js parses the document in your browser.
  2. Each requested page is rasterised at 72, 150 or 300 DPI.
  3. Pixels are saved as PNG with lossless compression, so the image is an exact copy of the rendered page.

Conversion quality: Exact. Pages are rendered at the chosen resolution and stored losslessly.

When to convert PDF to PNG

  • Documentation screenshots and slides where text must stay sharp
  • Diagrams, floor plans or charts you want to annotate in an image editor
  • Archiving a page as an image without quality loss

Limitations to be aware of

  • PNG files are larger than JPG, especially for scanned pages or photos. Use PDF to JPG for those.
  • Text becomes part of the image and is no longer selectable.
  • Pages are rendered on a white background, matching how PDF viewers display them.

PDF vs PNG

PDF. PDF (Portable Document Format) stores pages with fixed layout, fonts and images so a document looks the same on every device. It is built for viewing and printing rather than editing.

PNG. PNG uses lossless compression and supports full transparency. It is ideal for screenshots, logos and graphics with sharp edges, but photos saved as PNG are much larger than JPG.

Frequently asked questions

Is PDF to PNG lossless?

The PNG stores the rendered page without any compression loss. The only choice that affects detail is the resolution (DPI) you render at.

Why is the PNG bigger than the PDF?

A PDF stores text as compact font instructions, while a PNG stores every pixel. A full A4 page at 300 DPI is about 2480 × 3508 pixels.

Does it work offline?

Once the page has loaded, the conversion itself needs no network connection because it runs in your browser.

Are my files uploaded?

No. This tool reads and processes files directly in your web browser. Nothing is sent to Expensico's servers, and the data is discarded when you close or reload the page.
