PDF Compressor
Safely rewrite PDFs locally, show size change and download the result
Usage
Select a local PDF and run. The tool safely rewrites it locally in your browser, clears basic metadata, and shows original size, output size, and size change. If it cannot be reduced further, it reports that clearly. Notes: 1. The 15MB file size limit applies; larger files cannot be processed yet. 2. All processing is done locally in your browser; files are never uploaded. 3. After running, scroll the result preview to review each page.
