Email gateways still bounce large PDFs. Compression tools rewrite images inside the file—expect some quality loss if you aim for aggressive sizes.
Approaches
- LibreOffice Draw / export with lower JPEG quality.
- Online compressors for non-sensitive docs only.
- Ghostscript command line for batch jobs on a PC you control.
- Print to PDF again at “ebook” quality as a quick-and-dirty cut.
If something fails
Never upload contracts with personal data to random free web compressors—use local tools for those.
FAQ
