How Does Client-Side PDF Compression Work?
Standard PDF documents frequently contain uncompressed XML metadata, duplicate character font mappings, orphaned cross-reference tables, and unoptimized raster images.
I Want PDF strips away redundant bloated structural artifacts, deflates internal text streams, and writes an optimized, streamlined binary PDF document — all right inside your browser memory without uploading bytes to remote servers.
