Note: compressed pages become images, so text is no longer selectable.

100% private. Files are processed on your device and never uploaded to any server.

How it works — step by step

  1. Add the PDF you want to shrink.
  2. Pick a preset: Balanced is right for most documents; Strong squeezes the file hardest.
  3. Click "Compress PDF" and compare the before/after size in the result.

Frequently asked questions

How does PDF compression work here?

The tool re-renders each page as an optimized JPEG image at a lower resolution and rebuilds the PDF. This can dramatically reduce file size for scanned or image-heavy documents.

Will the text still be selectable after compression?

No — compressed pages become images, so text can no longer be selected or searched. If you need selectable text, keep the original alongside the compressed copy.

How much smaller will my PDF get?

It depends on the content. Image-heavy and scanned PDFs often shrink by 50–90%. PDFs that are already highly optimized may shrink less.
