Depending on the PDF content, you can expect 20-70% file size reduction. PDFs with large images see the biggest improvement.
We offer three levels: Low (best quality, ~20% reduction), Medium (balanced, ~50%), and High (smallest file, ~70%). Choose based on your needs.
We recompress embedded images using the browser's Canvas API and remove unused PDF objects. No file is uploaded to any server.
