How 20 KB Compression Works
Our engine analyzes the internal structure of your Pdf file and applies multi-pass optimization. First, it removes unnecessary metadata and redundant data streams. Then, it applies smart recompression to embedded elements. Finally, it performs structural optimization to meet your 20 KB target. The result is a smaller file that looks virtually identical to the original.
