PDF to PNG

Converts each page of a PDF into a PNG image. PNG uses lossless compression, so the output preserves every detail of the original page. Single-page PDFs download as a .png file; multi-page PDFs produce a ZIP.

How It Works

  1. Upload a PDF by clicking the drop zone or dragging a file onto it.
  2. Set the Scale slider to control output resolution.
  3. Click Convert to start processing.
  4. A single PNG or a ZIP archive downloads automatically.

Options

  • Scale -- ranges from 1.0x to 3.0x (default 2.0x). At 2.0x, a standard letter-size page renders at approximately 1,224 x 1,584 pixels. Higher scale values produce larger, sharper images at the cost of file size and processing time.

Output Format

  • Single page: filename.png
  • Multiple pages: filename_pngs.zip containing page_1.png, page_2.png, etc.

Use Cases

  • Capturing high-fidelity screenshots of PDF pages for presentations.
  • Extracting charts or diagrams that need crisp edges and no compression artifacts.
  • Preparing assets for web design from PDF mockups.
  • Creating lossless page images for OCR preprocessing.

Tips

  • PNG files are significantly larger than JPG. If file size matters more than perfect quality, use PDF to JPG or PDF to WebP.
  • At scale 1.0x, output matches the PDF's native resolution. Bump to 3.0x for print-quality exports.
