1. Security: Does the tool process files locally, or do they upload to external servers?
2. Speed: How long does the conversion take for standard documents?
3. Ease of Use: How many steps are required to upload and download?
4. Cost: Are there hidden fees or file size limits?
5. Additional Features: Batch conversion, cloud integration, or editing capabilities.

Let’s apply this rubric to real-world tools.
