Free Tool
Free Compress PDF
Shrink a PDF's file size by re-encoding its pages at a lower quality.
Free, private, no upload to a server. Everything happens in your browser.
All processing happens 100% in your browser — your PDF is never uploaded anywhere.
This re-encodes every page as a compressed image. It works best on scanned or image-heavy PDFs — text becomes part of the image and is no longer selectable or searchable afterward. If you need the text to stay searchable, don't run text-based PDFs through this tool.
