More InfoYouTube originally offered videos at only one quality level, displayed at a resolution of 320×240 pixels using the Sorenson Spark codec (a variant of H.263), with mono MP3 audio. In June 2007, YouTube added an option to watch videos in 3GP format on mobile phones. In March 2008, a high-quality mode was added, which increased the resolution to 480×360 pixels. In December 2008, 720p HD support was added. At the time of the 720p launch, the YouTube player was changed from a 4:3 aspect ratio to a widescreen 16:9. With this new feature, YouTube began a switchover to H.264/MPEG-4 AVC as its default video compression format. In November 2009, 1080p HD support was added. In July 2010, YouTube announced that it had launched a range of videos in 4K format, which allows a resolution of up to 4096×3072 pixels.

More InfoOn March 18, 2020, Thierry Breton, a European commissioner in charge of digital policy of the European Union urged streaming services including YouTube to limit their services. The request came as a result of the prevention of Europe's broadband networks from crashing as tens of millions of people started telecommuting, due to the COVID-19 pandemic in Europe. According to the EU, the streaming platforms should consider offering only standard definition, rather than high-definition, programs and users should be responsible for their data consumption. On March 20, YouTube responded by temporarily downgrading the videos in standard definition across the EU including the traffic in the UK as well.
More InfoGoogle formerly adhered to the Internet censorship policies of China, enforced by means of filters colloquially known as "The Great Firewall of China", but no longer does so. As a result, all Google services except for Chinese Google Maps are blocked from access within mainland China without the aid of VPNs, proxy servers, or other similar technologies. The Intercept reported in August 2018 that Google is developing for the People's Republic of China a censored version of its search engine (known as Dragonfly) "that will blacklist websites and search terms about human rights, democracy, religion, and peaceful protest". However, the project had been withheld due to privacy concerns.
