By identifying redundant data streams, we can reduce file sizes by up to **90%** while maintaining standard industry clarity.

Technical Basics

Our compression engine utilizes a sophisticated multi-stage algorithm. First, it identifies and removes redundant XObjects and font subsets that are not actively used in the document. Second, it applies downsampling to high-resolution images, converting them to the optimal DPI (Dots Per Inch) for screen viewing.

Finally, we utilize Flate Compression on the underlying document streams, significantly reducing the file size while adhering to the ISO 32000-2 standard to ensure the resulting PDF remains fully editable and readable on all devices.
