Free online AI tool that turns a photo plus an audio clip into a talking avatar with synced lips.

Lip Sync AI (lipsyncai.net) is a free, browser-based tool that animates a face to match an audio track. You upload a still image and an audio clip, and the model drives the mouth, jaw, and facial motion so the subject appears to be speaking the words. The result is a talking avatar — a "talking head" video — generated without filming, a green screen, or any editing software.
It is audio-driven rather than text-driven. The current workflow takes an image (JPG, PNG, or WEBP) plus an MP3 audio file; on-platform text-to-speech is listed as an upcoming feature, so for now you bring your own voice or a separately generated voiceover. It also offers a video mode that re-syncs the lips of existing footage to new audio (useful for dubbing), and a multi-speaker mode. It is not limited to human faces — cartoons, illustrations, animals, and stylized characters can be animated too.
Lip Sync AI is one of several similarly named free lip-sync tools that appeared as the underlying face-animation models matured. Its draw is the price and the lack of friction: new users get complimentary credits, and there is no need to install anything. Usage runs on a credit system — the site lists 15 credits per second of generated video with a 5-second minimum — and a paid upgrade unlocks more credits, longer renders, and priority processing. Specific limits, credit costs, and feature availability change as the product ships, so treat any exact number as a snapshot and confirm it on the site.
Like every lip-sync generator, it does one thing: produce the clip. It does not write your script, generate the voice (yet), caption the video, resize it per platform, or publish it anywhere. Those are separate steps.
Lip Sync AI hands you a single talking clip with the mouth moving in time with the audio. That clip is a raw asset, not a post — it has no captions, it is sized however the tool exported it, and it lives on your hard drive. Kompozy is the layer that turns it into published content. Drop the export into Kompozy and it burns in branded captions (essential, because most feeds autoplay muted and a talking-head video with no on-screen text gets scrolled past), reframes the clip to each platform's aspect ratio, and lets you stack a hook overlay through HyperFrames so the first silent second actually stops the scroll. Then it schedules and publishes the same clip across TikTok, Reels, YouTube Shorts, Facebook, LinkedIn, X, Pinterest, and Threads from one queue.
There is also a make-vs-bring-in decision worth naming. If you want a one-off animated character or a quick dub, Lip Sync AI's free credits are a fine starting point and Kompozy finishes the job. But if you need a recurring, brand-consistent spokesperson, Kompozy generates avatar video natively through its Persona Shorts and Persona HeyGen formats — HeyGen-driven talking-head video with auto-captions and your own voice and likeness held consistent by an AI Influencer persona — so you skip the upload-and-import loop entirely and one approval renders a week of on-brand clips.
Lip Sync AI (lipsyncai.net) is a free, browser-based tool that turns a still photo and an audio clip into a talking avatar by syncing the face's lip and jaw movements to the audio. It also has a video mode for re-syncing existing footage to new audio, and supports non-human images like cartoons and animals.
It offers free access with complimentary credits for new users, which is enough to try short clips. Usage runs on credits — the site lists 15 credits per second of generated video with a 5-second minimum — and a paid upgrade unlocks more credits, longer renders, and priority processing. Check the site for current limits.
It is audio-driven: you upload an MP3 (the site lists a 20MB limit) along with the image, and the model syncs the face to that audio. Built-in text-to-speech is listed as an upcoming feature, so for now you supply or separately generate the voiceover.
Lip Sync AI is a lightweight free tool focused on photo-to-talking-avatar and audio-driven dubbing. sync. is a developer-grade lip-sync and visual-dubbing platform built by the Wav2Lip team, and HeyGen is a full avatar-video studio with cloned voices and stock avatars. Lip Sync AI trades depth and consistency for being free and frictionless.
Lip Sync AI generates the clip but does not publish it. Bring the export into Kompozy to add branded captions, reframe it per platform, and schedule and publish across TikTok, Reels, YouTube Shorts, Facebook, LinkedIn, X, and more from one queue — or generate brand-consistent avatar clips natively with Kompozy's Persona Shorts.
