LipSync.video

LipSync.video is a free, browser-based AI tool that automatically synchronises audio with the lip movements of people in videos and photographs. You upload your video or image along with audio content, and the tool generates a new video where the person's lips match the audio timing and mouth shapes. There's no software to install and no account required to get started. The tool is designed for anyone needing to match dialogue to video, whether that's dubbing content into different languages, creating voiceovers for existing footage, or producing speaking videos from static images. It handles the technical work of lip syncing, which would otherwise require manual frame-by-frame animation or professional video editing skills. Because it operates entirely online and remains free, it removes cost and technical barriers for content creators, educators, and small teams who need realistic lip sync results without investing in expensive software or hiring specialists.
