How it works

  1. Open the tool and choose a PDF from your device.
  2. Review the options and page range. The tool opens after the PDF loads.
  3. Create a separate copy, then check the downloaded result before sharing.

What to expect

JPEG image modes can soften fine print; some PDFs are already compressed.

Your open document stays unchanged. Processing happens on your device. Loading browser libraries initially requires internet; very large documents may exceed device memory.

Desktop app

The same tool is in the Fire PDF desktop app for Windows and Mac, which runs offline and opens PDFs straight from your computer. Download it with a 7-day free trial.
