What Is Upload Speed and Why Does It Matter for Streaming?

When streaming on platforms like Twitch, YouTube, or social media, upload speed is crucial for ensuring smooth broadcasts. It determines how quickly your video and audio reach viewers, affecting the quality of the stream. A slow upload speed can lead to buffering, pixelated video, audio-video sync issues, or disconnections.

“Upload speed is the rate at which data is sent from your device to the internet, and it plays a crucial role in ensuring smooth, high-quality streaming, especially for live broadcasts and video calls.”.

– Ram Mohan
