PDF Compressor
Shrink a PDF's file size by removing redundant internal structure.
- Typical savings: a few percent to ~15%
Honest heads-up: this optimizes the PDF's internal structure but doesn't recompress embedded images — for PDFs made mostly of large scanned images, savings will be modest. Our Pro compressor recompresses embedded images too and typically does much better on those.

Pro recompresses embedded images too — typically 3-5x more reduction than this free tool, plus batch processing for up to 100 PDFs at once.
