YouTube AV2 codec 2027: 30% less data for video streaming

YouTube is bringing a new technology to cut how much data your videos eat up. Starting in early 2027, the platform will roll out AV2, a new video format that could reduce data use by roughly 30% compared to what YouTube uses today. For Ghanaians on tight data bundles, this could mean more hours of video before you run out.

Think of it like this: a video codec is a digital box. The smaller the box, the less data it takes to send the video to your phone or computer. AV2 is that smaller, smarter box. It packs video into less space without making it look noticeably worse.

YouTube’s current video format is called AV1. AV2 compresses video about 30% better than AV1, meaning YouTube can either show you the same quality video using less data, or show you sharper video without using more data.

What does this mean for your data bundle?

If you’re watching YouTube on a mobile data plan, AV2 could stretch your bundle further. The exact savings will depend on what you’re watching and your quality settings, but the potential for reduced data consumption is there. That’s more YouTube before you hit your limit or have to pay for extra data.

YouTube also hints that AV2 could make streaming smoother on slower connections. If your internet keeps buffering, AV2 might help.

YouTube says AV2 will arrive on the web version (YouTube.com) in early 2027. But here’s the catch: your phone or device needs to support AV2 playback first. YouTube hasn’t said when the mobile app will get it.

Many phones and computers made today don’t have the dedicated chip needed to decode AV2 smoothly, which means older devices might struggle. Google showed AV2 working in Chrome, but broader support across all devices will take time.

Not guaranteed. The actual savings depend on what you’re watching, the video quality you choose, and how YouTube encodes each stream. Some videos might save you less, others more.

But the point is clear: YouTube is trying to make streaming leaner, and that helps everyone with a capped data plan.

In 2027, keep an eye on your YouTube app for AV2 support. If you’re on a limited data bundle, this feature could buy you extra viewing time before you need to buy more data. For now, stick to WiFi when possible and monitor your data use if you’re still on the web version once AV2 rolls out.
