Shrink a PDF's file size so it fits under email or upload limits.
This tool re-renders each page as an image at a reduced quality and rebuilds the PDF from those images. It works best on PDFs made of scanned pages, photos, or graphics-heavy documents. For text-only PDFs that are already small, compression may only save a little.
Because it runs fully in your browser, larger or longer PDFs may take a little longer to process — that's normal, just let it finish.
