Lip Sync AI
— Match Any Voice to Any Face
Upload a video and an audio file. The lip sync AI rewrites the mouth movements to match your new voice track. Teeth, jaw, expressions — all stay natural.
How Lip Sync AI Works
No timeline. No keyframes. No frame-by-frame mouth animation. The lip sync AI takes two files and a sync mode — that's it. Upload and download.
1. Upload Your Video
Drag and drop a video with a visible face. MP4 or MOV. The lip sync AI detects the face automatically and prepares it for syncing.
2. Upload Your Audio
Drop in the audio you want the face to speak. MP3, WAV, M4A, AAC, OGG, or FLAC. Any language works.
3. Pick a Sync Mode
Audio longer than the video? Choose how to handle it — trim, loop, bounce, pad silence, or remap speed. The lip sync AI adapts to your choice.
4. Generate and Download
Hit generate. The lip sync AI processes your clip in the cloud and delivers a download link when it's ready. No GPU needed on your end.

Why Lip Sync AI Beats Manual Dubbing
Replacing dialogue used to mean re-recording the whole scene or hiring a video editor to hand-animate mouth shapes frame by frame. This lip sync AI does it in minutes. Upload your clip, drop in the new audio, and the AI handles the rest.
Lip Sync AI That Keeps Faces Real
Old lip sync tools paste a blurry mouth patch over the original. It looks fake instantly. This lip sync AI rebuilds the lower face from scratch — jaw movement, teeth visibility, skin texture all match the surrounding video. The lip sync AI output is indistinguishable from the original recording.
Lip Sync AI for Any Language
Record a video in English. Dub it into Spanish, Japanese, or Hindi. The lip sync AI adjusts mouth shapes to match the phonetics of your new audio track. Multilingual lip sync AI means you publish in more languages without re-filming.
Five Sync Modes
Audio longer than the video? Shorter? The lip sync AI gives you five ways to handle it — trim the audio, loop the video, bounce playback, pad with silence, or remap the video speed. Pick what fits your project.
Lip Sync AI Features
Two model tiers. Five sync modes. Cloud processing. Built for creators who need fast, clean lip sync without complex software.
Pro Model — Maximum Quality
The Pro lip sync AI model uses diffusion-based super-resolution for the sharpest results. Best for close-up shots, 4K footage, and anything that will be viewed on a big screen. 2 credits per second.
Standard Model — Fast and Affordable
Need quick turnaround for social posts or drafts? The Standard lip sync AI model runs faster at 1 credit per second. Good enough for most TikTok, Reels, and YouTube Shorts content.
Lip Sync AI Duration Handling
Video is 10 seconds but audio is 25? The lip sync AI offers five sync modes: trim audio to fit, loop the video, bounce playback forward-and-reverse, pad silence, or remap video speed to match exactly.
Cloud Processing — No GPU Needed
The lip sync AI runs on cloud servers. Works on any laptop, tablet, or phone with a browser. Upload your files, come back when it's done. No installs, no hardware requirements.
Any Audio Format Works
Upload MP3, WAV, M4A, AAC, OGG, FLAC, or WebM audio. Record a voice memo, export from a podcast, or use a TTS clip. Feed any audio into the lip sync AI and get synced video back.
No Watermark on Output
Every lip sync AI render downloads clean — no watermark, no branding overlay. Use the output directly in client work, YouTube videos, or paid ads without post-processing.
Creators Use Lip Sync AI Every Day
See how content creators and marketers use lip sync AI for dubbing, localization, and content creation.
Carlos Mendez
Bilingual YouTuber, 120K subscribers
“I run a bilingual YouTube channel. Used to re-film every video in Spanish. Now I record once in English and run it through the lip sync AI for the Spanish version. Saves me 3 hours per video.”
Rachel Lin
Marketing Agency Owner
“Our clients needed product demo videos in 4 languages. Hiring voice actors and editing each version manually was costing us $2K per video. This lip sync AI cut that to under $5 per language.”
Darius Cole
TikTok Creator, 280K followers
“I make comedy skits where I dub over movie scenes. The old tools made mouths look like rubber. This lip sync AI actually matches the jaw and teeth. My audience can't tell it's dubbed.”
Mika Tanaka
Podcast Video Editor
“The sync modes saved my project. My voiceover was 8 seconds longer than the video. The 'remap' mode stretched the video just enough. No re-editing needed.”
Jordan Avery
Freelance Video Editor
“Tried three other lip sync tools before this one. Two required downloads and GPUs. One was cloud-based but the results looked terrible. This one just works, and it's in the browser.”
Lip Sync AI FAQ
Everything you need to know about using lip sync AI for video dubbing and content creation.
What is lip sync AI?
Lip sync AI is a tool that matches mouth movements in a video to a new audio track. Upload a video with a face and an audio file. The lip sync AI analyzes the speech and rewrites the lip movements frame by frame. The result looks like the person is naturally speaking the new audio.
What languages does lip sync AI support?
Any language. The lip sync AI works with the audio you provide — it matches mouth shapes to the actual sounds, not to a specific language model. English, Spanish, Japanese, Hindi, Arabic, Mandarin — any language works. Record your audio and the lip sync AI handles the rest.
What's the difference between Pro and Standard?
The Pro lip sync AI model uses diffusion super-resolution for sharper results. Best for 4K footage and close-ups. Costs 2 credits per second. The Standard model is faster and costs 1 credit per second. Good for social media content where pixel-perfect quality is less critical.
What are sync modes?
When your audio and video are different lengths, sync modes tell the lip sync AI how to handle it. Cut Off trims the audio. Loop replays the video. Bounce plays forward then reverse. Silence pads the audio. Remap adjusts video speed to match audio duration exactly.
How long does lip sync AI processing take?
Processing time depends on video length and the model you pick. Standard is faster. Pro takes longer but delivers higher quality. Most clips under 30 seconds finish in a few minutes. The lip sync AI runs in the cloud — you can close the browser and come back.
What file formats can I upload?
Video: MP4 or MOV. Audio: MP3, WAV, M4A, AAC, OGG, FLAC, or WebM. Video files up to 100MB. Audio files up to 50MB. The lip sync AI outputs MP4.
