PDFOptim

PDFOptim is a simple and intuitive way to compress, reduce, and optimize PDF file size. It provides easy and effective ways to compress large, image-heavy PDF files using an extensive set of options and presets. Supports batch processing and provides real-time original as well as optimized PDF document preview for side-by-side quality comparison.

Compressed PDF documents requires less disk space for storage, and faster uploads and downloads save transmission time and cost. PDFOptim has compression-filter options to help you to reduce PDF file size without compromising the document's integrity, rewriting the entire PDF document as efficiently as possible. Some PDF documents might not get compressed, because they may be already compressed or have little to compress.
