About PDF Compressor

PDF Compressor reduces a PDF’s file size by re-compressing its pages, entirely inside your browser. It’s the private alternative to upload-based compressors for contracts, statements and other sensitive documents.

How to use PDF Compressor

  1. Drop the PDF you want to shrink.
  2. The tool re-compresses the pages locally and reports the new size.
  3. Download the smaller PDF — the original never leaves your device.

Frequently asked questions

Is my PDF uploaded to a server?
No. Unlike most online compressors, this runs 100% in your browser, so confidential PDFs never leave your device.
Will it ruin the quality?
It re-compresses images and streams to cut size while keeping the document readable; results depend on what the PDF contains.
