How In-Browser PDF Compression Works

PDF files typically balloon in size due to uncompressed scanned images, embedded print-resolution photos, and duplicate font tables. Infyn applies advanced multi-strategy optimization locally on your machine:

Raster & Scan Downsampling

Renders heavy pages at target DPI (72–150 DPI) and applies optimal JPEG quantization to remove megabytes of hidden visual bloat.

Stream & Object Compaction

Strips orphaned objects, duplicate metadata streams, and packs PDF cross-reference tables into compressed object streams.

Target Size Budgeting

Dynamically allocates bytes per page to guarantee documents easily slip under strict 200KB or 500KB portal upload limits.
