YouTube reportedly plans AV2 web rollout for early 2027

YouTube says it plans to bring the AV2 video codec to the web version of its platform as soon as early 2027, a move that could improve picture quality at the same bitrate or reduce bandwidth use for comparable quality. The timing comes after the Alliance for Open Media published the definitive AV2 specifications and while AV1 adoption is still spreading across devices and services. ¹

AV2 is designed to be more efficient than AV1. Android Authority, citing reporting from FlatpanelsHD, says the expected gain is roughly 25% to 32%, although the practical benefit will depend on the encode, the viewer’s connection and the hardware decoding the stream. ¹ A more efficient codec does not automatically mean every video becomes sharper: it gives the platform more room to trade bitrate, resolution and image quality against one another.

The first rollout is web-only

The reported plan starts with YouTube on the web rather than immediately covering phones, TVs and dedicated media players. That limited launch makes sense because codec support is a chain: the service needs to encode and deliver the files, browsers need to recognise them, and hardware or software decoders need to play them without turning playback into a battery or performance problem.

YouTube says more than 90% of its catalogue, weighted by watch time, was already available in AV1 by March 19, 2026. Its engineering team has also described more efficient video formats as a foundation for multi-video experiences and higher-resolution, lower-interruption playback. ¹² The company’s wider 2026 product announcements show that it is continuing to invest in the platform’s viewing and creator technology, but those announcements should not be confused with an AV2 launch date. ²

What it could mean for viewers

If AV2 arrives as described, the most obvious benefit may be fewer buffers or steadier quality on a connection that currently struggles with high-resolution YouTube. Viewers with fast broadband could instead see better image quality without a proportional increase in data use. The result will vary by browser, device, video and region while the rollout expands.

There is also a long tail to the announcement. AV1 launched in 2018, yet broad hardware encoding support took years to appear. Android Authority notes that current phones and media players are not broadly ready for AV2, so the early web rollout may rely heavily on software support before dedicated decoders catch up. ¹ That means AV2 can be an important infrastructure change without producing an instant visual upgrade on every screen.

Our opinion

YouTube’s AV2 plan is promising precisely because it is boring infrastructure: better compression can make a service feel more reliable without asking viewers to change how they watch. The sensible expectation is a gradual improvement, not a dramatic switch flipped across the entire catalogue in early 2027. Browser support, device decoding and regional availability will decide whether the efficiency gains translate into fewer pauses or simply give YouTube more headroom for higher-quality streams. Until those pieces arrive, AV2 is a roadmap rather than a feature viewers can enable today. ¹²
