How to Compress PDF Files Online
This free PDF Compressor reduces your PDF file size by re-rendering each page as a compressed JPEG image and reassembling them into a new, much lighter PDF. Perfect for email attachments, online form uploads, or saving storage space.
How It Works
- Your PDF is opened and each page is rendered using Mozilla's PDF.js technology.
- Each page is converted to a JPEG image with adjustable quality.
- The images are reassembled into a new, smaller PDF using jsPDF.
- Everything runs 100% in your browser — files never leave your device.
