LipSync is an online AI tool that automatically matches lip movements in a video to your audio or text. Upload a clip, add a voice track (or text), and the model adjusts mouth motion to the sound for more natural-looking speech.
How it works
- Upload a video file in mp4, webm, or ogg (up to 30 MB)
- Choose an aspect ratio that fits your content, including 9:16 vertical and 16:9 horizontal
- Add audio or text and generate a lip-synced result
Modes: Lip Sync 1.0 and 2.0
- Lip Sync 1.0: designed for portrait-style videos and faster, basic lip-sync output
- Lip Sync 2.0: aims for more realistic lip-sync and facial expression, and supports different character types
Common use cases
- Short-form videos and podcast clips
- Talking photos and animated drawings
- Kids/cartoon-style characters and other avatars
- Pet videos and experimental “talking” content
No registration is required, which makes it practical for one-off tasks, quick tests, and prototyping.
