Reduce PDF size with lossless or image-based compression.
Image-based compression flattens pages: selectable text, links, forms and accessibility tags are lost. Resolution and quality apply only to this mode. Lossless compression may provide little or no reduction. If the output is larger, we return your original file.
How it works
Choose your PDF, choose your options, then click the blue button. Your download appears when processing finishes.
Your documents stay private
All processing happens in your browser. Files are never uploaded. Password-protected or damaged PDFs are not supported. Large documents may need a smaller batch on mobile devices.
