- Foxit Reader — lightweight with more features than Sumatra.
- Adobe Reader — compatible but heavier; use if you need advanced Adobe-specific features.

| Platform | Windows 7/8/10/11 (check specific app page), Android, iOS, Web |
| RAM | From 256 MB (Sumatra) to 2+ GB (Adobe/Drawboard recommended) |
