What is h264ify?

h264ify is a unique Chrome extension designed to optimize YouTube streaming. By default, YouTube uses VP8/VP9 encoded videos, which can slow down performance on less powerful devices due to lack of hardware acceleration. h264ify solves this by making YouTube stream H.264 videos, a format commonly hardware-accelerated by GPUs for smoother playback and reduced CPU usage. A must-have for seamless, energy-efficient viewing.

Try h264ify if YouTube videos stutter, take up too much CPU, eat battery life, or make your laptop hot.

By default, YouTube streams VP8/VP9 encoded video. However, this can cause problems with less powerful machines because VP8/VP9 is not typically hardware accelerated.

In contrast, H.264 is commonly hardware accelerated by GPUs, which usually means smoother video playback and reduced CPU usage. h264ify makes YouTube stream H.264 videos instead of VP8/VP9 videos.
