If you need a lightweight, offline PDF reader without bloat, consider these free, secure alternatives that run well on older hardware:

| Software | Lightweight? | Offline? | OS Support | Security Updates | |----------|--------------|----------|------------|------------------| | Sumatra PDF | ✅ (1.5 MB) | ✅ | Win XP to Win 11 | Active | | Foxit Reader 9.x | ✅ | ✅ | Win 7+ | Limited (but newer than Adobe 9) | | PDF-XChange Editor (Free) | ✅ | ✅ | Win 7+ | Active | | Okular | ⚠️ (via KDE) | ✅ | Win/Linux/Mac | Active | | Adobe Acrobat Reader DC (Modern) | ❌ | ❌ (needs online for features) | Win 10+ | Active |
