Use it well Examples, checks, limits, and recovery paths
Bad inputs
- Already optimized PDFs.
- Files where visual fidelity matters more than size.
- Documents that still contain pages you plan to remove.
Output checklist
- Compare the before and after file size.
- Open image-heavy pages at normal zoom.
- Check page count, forms, links, and metadata after compression.
Failure modes
- Compression may not shrink vector-heavy or already optimized PDFs.
- Visual fidelity can change.
- Encrypted or malformed PDFs fail safely.
Runtime limits
- Temporary server job.
- Best after page deletion/reordering is finished.
- Not a privacy cleanup by itself.
