How it works

Each page of your PDF is rendered and re-encoded as a JPEG image at your chosen quality level, then reassembled into a new PDF. This significantly reduces file size, especially for PDFs with high-resolution images.

  • 100% client-side — your files never leave your browser
  • Best for PDFs with images, scans, or graphics
  • Lower quality = smaller file, higher quality = better readability
