- Image-only clues
- Downloadable report
Output and quality
Results are estimates based on browser-accessible information.
Limitations
Page-level and image-complexity findings are estimates because browser libraries do not expose exact internal object sizes.
Tips for better results
- Compare similar documents.
- Treat image-only findings as clues.
Troubleshooting
Why do page totals not equal file size?
Resources can be shared across pages.
Why is no smaller PDF created?
This is an analyzer, not a compressor.
