Compress large PDF files while maintaining quality. Fast, secure and free.
Convert each page of your PDF into a compressed JPG image and generate a much lighter PDF.
• The PDF is read in your browser using PDF.js
• Only the generated JPG images are sent to the server to build the new PDF
• In SUPER mode, pages are rendered at lower resolution, grayscale and highly compressed to reduce size to a minimum.
Compression progress
After selecting the PDF, the pages will be rendered as images to allow compression. Then a new compressed PDF will be generated for download.
