Turn one portrait into a talking video
Add a clear portrait, then type the dialogue or upload a recording. The generator follows the speech timing to create mouth and facial movement while keeping the person recognizable.
Text or recorded speech
Use an AI voice for a written script, or keep your own timing and pronunciation with an uploaded recording.
720p or 1080p output
Choose 720p for quick drafts or 1080p when facial detail matters more.
Price shown before generation
The duration estimate updates before you start, so the credit cost is clear.
How to make a lip sync video online
The full workflow stays on one page, from choosing the face to downloading the finished MP4.
Choose a portrait
Upload a front-facing JPG, PNG, or WEBP, or begin with a preset.
Add the speech
Write the exact line and preview a voice, or upload an MP3, WAV, or M4A file.
Check and generate
Confirm the estimated duration, resolution, and credits, then create and download the video.
Start with a face the model can read
A strong source image and clean speech prevent many avoidable lip-sync artifacts.
Keep the mouth visible
Use one sharp, front-facing subject without hands, hair, masks, or microphones covering the lower face.
Use even light
Avoid deep shadows across the eyes or mouth so facial details stay consistent between frames.
Write for the ear
Short sentences and punctuation create clearer pauses. The spoken result must fit within 60 seconds.
Use a talking portrait when a speaker helps
A short face-to-camera clip can make a message feel more direct without recording a new take.
Product and support updates
Create a short introduction, feature note, onboarding message, or help clip.
Social hooks
Build talking-photo openings and character clips for TikTok, Reels, and Shorts.
Lessons and personal messages
Give a narrator or illustrated character a voice for a lesson, greeting, invitation, or announcement.
From portrait to finished video in one workspace
Compare real examples, preview voices, check the price, generate, and return to previous results without moving files between separate tools.
30 voices with previews
Hear each voice before choosing it, with a portrait preview that makes the selection easier to understand.
Examples beside your history
Switch between ready-made examples and your processing, completed, or failed tasks.
Connected video tools
Continue with video generation, voice generation, or frame extraction when the project needs more than one clip.

AI Lip Sync Generator FAQ
Practical answers about portraits, audio, duration, resolution, credits, and failed tasks.
It turns a still portrait into a talking video. You add written dialogue or a speech recording, and the model creates mouth and facial movement that follows the audio timing.
Yes. Upload an MP3, WAV, or M4A file when you want to keep a specific voice, pronunciation, or performance.
Use one sharp, front-facing face with even lighting and a clearly visible mouth. Strong angles, blur, and objects covering the face can reduce consistency.
Each generation can be up to 60 seconds. Written scripts have no fixed character cap; the estimated speaking time must stay within the 60-second limit.
Use 720p for drafts and everyday social clips. Choose 1080p when the final export needs more facial detail. The page shows the cost before generation.
720p costs 5 credits per second and 1080p costs 9 credits per second. The estimate updates from the expected or uploaded audio duration.
The failed task remains in Generation history. If credits were deducted for a task that could not finish, the refundable amount is returned automatically.
