| Spec score · PDF Compression Software | 9.1 (#2) | 8.1 (#15) |
| API | The documentation describes a REST API for programmatic image compression. | The Python package provides a compress() API as well as the hankpdf console command. |
| Compression | The site says Compresto can reduce file sizes by up to 90% while preserving visual quality. | The README gives a target of 8–15× typical compression and up to 200× on text-dominant scans, while warning that already-efficient files may not shrink. |
| Support | The privacy policy lists [email protected] for questions about privacy or data handling. | The README directs users who remain stuck to open a GitHub issue and attach the output of hankpdf --version. |
