How to use Compress PDF

  1. Choose a PDF.
  2. Select balanced, stronger or maximum compression.
  3. Compress and compare the new file size before downloading.

What this tool changes

The browser renders each page and rebuilds it as a compressed image. This is effective for scans and photo-heavy PDFs but deliberately trades resolution and selectable content for a smaller file.

Important limitation

Compression flattens pages, so selectable text, links and forms are removed. Keep your original.
