What this tool does

AV1 is an efficient video format used by newer phones, screen recorders and some cameras. Many older phones, TVs, WhatsApp and video editors can't open AV1 videos.

This tool re-encodes the video with H.264 video and AAC audio, which work almost everywhere. It uses your device's and browser's own video decoder, so Chrome or Edge on a computer gives the best results.
