Upload File Fast: Tips to Maximize Speed
- Use a wired connection — Ethernet is faster and more stable than Wi-Fi for large uploads
- Close other bandwidth-heavy apps — streaming, downloads, and video calls compete for upload bandwidth
- Upload during off-peak hours — your ISP may have less congestion at night
- Use Chrome or Firefox — both handle large file uploads reliably
