LipSync.show is an online AI lip-syncing tool that makes any video character speak a new audio track with natural mouth movements, directly in your browser.
What is LipSync.show?
LipSync.show is a web-based AI lip sync service that takes a video containing a human face speaking and an audio file with new speech, then produces a new video where the mouth movements match the new audio. It runs entirely online, so you only need a browser — including on mobile — and no video editing skills are required. The service is positioned for content creators, marketers, and e-commerce sellers who need quick video retalking.
What makes LipSync.show stand out?
The platform stands out by offering three specialized AI models, each tuned for different workflow needs.
- Latent Sync — ultra-fast processing for quick projects, supporting videos up to 5 minutes long.
- Kling Lip Sync — automatically extends the video when the audio is longer, with no maximum length limit, ideal for long audio tracks.
- Sync V1.9 — highest quality output with 5 loop modes, supporting videos up to 10 minutes for full control.
Additional concrete features:
- Supported formats — accepts video files in mp4, mov, webm, m4v, and gif; audio in mp3, wav, ogg, aac, and m4a.
- Fast processing — a 1080p video under 5 minutes typically takes about 5 to 8 minutes to process.
- Freemium to start — new registered users receive 20 free credits (about 20 seconds of video) to try before buying a subscription.
Who should use LipSync.show?
LipSync.show serves anyone who needs to change the spoken audio in an existing video without reshooting.
- Content creators making TikTok or YouTube Shorts — repurpose an existing clip with a new voiceover and export directly for short-form platforms.
- E-commerce sellers — quickly change the audio on product videos to match different markets or promotions without reshooting.
- Podcasters and news producers — turn audio episodes into video clips where a presenter appears to speak the script, as shown in the site's blog articles.
- Marketers — create localized ad versions or product explainers with a different voice track while keeping the original visuals.
What can you do with LipSync.show?
The tool directly supports three practical use cases.
- Video repurposing: Upload a video of a person speaking, add a new script in audio form, and download a matched clip for TikTok, YouTube, or Instagram.
- Long-form audio adaptation: Use Kling Lip Sync when the audio is longer than the video — the tool extends the video automatically, removing the need for manual trimming.
- Multi-language content: Swap the original speech with a translated audio track to create localized versions of the same footage.
How does LipSync.show work?
The process happens in three simple steps: upload, process, and export.
- Upload your source video (must contain a human face speaking) and your target audio file.
- The AI analyzes facial features in the video frames and aligns them with the phonemes of the new speech to generate realistic lip movements.
- Once processing finishes, preview the result in your browser and download the new video.
