Features & Overview of PDF Compressor
The compressor rewrites the document structure, removes unused objects and metadata, and re-saves the file with object streams enabled. Text-heavy PDFs and documents exported from Office typically shrink noticeably.
Scanned PDFs are mostly made of photographs, so if you need a dramatic reduction there, compress the source images first and rebuild the document.
