About this tool
What is AI Lip Sync?
AI lip sync reshapes the mouth in a video so it matches a different audio track. You upload the clip and the new audio, and the speech lines up on its own — no cutting or frame-by-frame editing.
Most people reach for it for three jobs: dubbing a video into another language, fixing footage where the sound drifts out of sync, and making a clip say something new. If you can record or upload the audio, the tool can sync it.
Choose Auto or a named model such as a certified Sync, VEED, HeyGen, PixVerse, or Kling deployment. Availability, input limits, and price are validated from the live server catalog before any credits are reserved.
Features
Everything you need, nothing you don’t.
Sync that tracks the words
The mouth follows consonants and pauses, not just an open-close on the beat.
Audio, voice, or text
Upload an audio file, record in the browser, or type text and let the built-in voice read it.
Multiple models
Auto compares eligible deployments, while named selection keeps the requested model product.
HD export
Download in HD where your mode and settings allow.
Server price estimate
The app estimates the request from your inputs; the final charge uses verified uploads and active pricing when you generate.
Any language
Sync audio in any language — handy for dubbing one video into several.
Files aren’t kept
Uploads are processed securely and deleted after 30 days.
Private media workflow
Validated uploads and generated outputs stay private and follow the configured retention policy.

FAQ
Questions about AI Lip Sync Generator.
What does an AI lip sync generator do?
It changes the mouth movement in a video so it matches new audio. The speech timing lines up automatically, so you don’t edit frame by frame.
How do Auto and named model selection differ?
Auto chooses the lowest-cost compatible certified deployment for the verified inputs. Named selection keeps your chosen logical model and only permits an equivalent deployment fallback.
What files can I upload?
Video: MP4, WebM, or MOV up to 100MB. Audio: MP3, WAV, OGG, M4A, WebM, or AAC up to 50MB. Individual models may enforce stricter limits before billing.
How long does it take?
Processing time depends on clip length, model, provider load, and retries. The job view shows the current state until the private output is ready.
Can I use it to dub a video into another language?
Yes. Add the translated audio, or type the translated script, and the mouth re-syncs to it. Dubbing is one of the most common uses.
Do you have a version for a single photo?
Yes. If you’re starting from one still image instead of a video, use AI Talking Photo. To make a photo sing along to a song, use AI Singing Photo.
