About This Tool
This free online PDF Compressor runs locally in your browser. Fast rewrite mode keeps original page structure and is the safest first choice. Raster mode redraws each page as an image, which can produce smaller files but reduces text/search quality.
Use fast mode for regular office PDFs. Use raster mode for image-heavy or scanned files when strong size reduction matters more than selectable text.
