How to compress a PDF online free

Reduce your PDF file size so it is easy to email or upload. This compressor works best for scanned documents and image-heavy PDFs. Note: pages are rebuilt as optimized images, so text becomes non-selectable — ideal for scans, photos, and forms. Everything runs in your browser; your file is never uploaded.
