The Science of PDF Compression
Why is a simple five-page PDF sometimes 20MB? The answer usually lies in unoptimized images, embedded font subsets, and redundant metadata. PDF compression isn't just about "zipping" a file; it's about re-engineering the internal structure of the document to be as efficient as possible.
Lossy vs. Lossless Compression
Understanding the difference is key to getting the best result:
- Lossless: Removes redundant data without changing a single pixel. Best for text-heavy documents and legal records.
- Lossy: Downsamples high-resolution images. Best for presentations and photo-rich reports where absolute pixel perfection isn't required.

Practical Tips for Maximum Reduction
1. Clean Up Before Compressing
If you have extra pages you don't need, use the Split tool to remove them first. There's no point in optimizing data you'll never use.
2. Flatten Form Fields
Interactive forms can add significant weight. If the form is complete, consider flattening it to standard PDF content to save space.
