Local vs cloud PDF tools: a practical privacy guide

| Feature | Aladdin | Typical cloud converter |

| Works on locked-down networks | Often yes (offline) | Needs outbound upload |
| Verification | /privacy-verification guide | Trust vendor policy |
| Speed for large files | Device-dependent | Fast upload + queue |
