Reduce PDF file size while maintaining quality. Free and secure.
Reduce PDF file size without losing quality
Upload the PDF you want to reduce. The tool shows the original file size. Large PDFs are often caused by embedded high-resolution images — these compress very well.
High compression gives the smallest file but may reduce image quality. Low compression preserves quality with a modest size reduction. For text-only PDFs, all levels look identical.
Download the smaller PDF. The document structure, text, and links are preserved. All processing happens in your browser — your PDF is never uploaded to a server.
