Can i change my tutorial video quality to less pixels?

how can i change the video quality to minimum so that it uses minimum data?

Most of freeCodeCamp’s video content is on YouTube, where you can adjust quality settings. I don’t think that the videos that are linked within the curriculum are not required, and I strongly recommend AGAINST watching them most of the time.

freeCodeCamp tries to be considerate of students and reduce necessary data, which is why we try not to rely directly on videos.
