Compress Scanned PDF
Compress a scanned PDF that ballooned from photos. Re-encode the images to shrink the file hard.
Why it matters: Image-heavy and scanned PDFs shrink the most, since compression re-encodes embedded pictures more tightly.
How to Compress Scanned PDF
- Open the Compress Scanned PDF tool and add your PDF (drag-and-drop or browse — it never leaves your device).
- Pick Smaller or Tiny — scanned and image-heavy PDFs shrink the most when pictures are re-encoded.
- Click Compress PDF. Pages are re-rendered as optimized images, so the lighter file downloads instantly.
- Download the result — everything runs in your browser, nothing is stored or sent.
