How to: Optimize PDF for Web

Tips for best results
- Combine with Compress PDF for image-heavy files.
- Set a clear title with Edit PDF Metadata – it shows in browser tabs.
Why optimise PDFs for the web
Large, bloated PDFs load slowly on mobile data and can hurt user experience. Removing unused objects, duplicate resources and embedded scripts creates a cleaner file that opens faster and is safer to publish.
