Yes, completely free. No hidden fees, no subscriptions, no credit card required. Generate unlimited videos without any charges.
Do I need to create an account?

Are my files uploaded to your servers?

What audio formats are supported?
We support all common audio formats including MP3, WAV, AAC, M4A, OGG, and FLAC. Any audio file your browser can play will work.
How does the word highlighting work?
Words are highlighted one at a time at a fixed interval you control — from 0.3 seconds per word (very fast) to 4 seconds per word (slow). The text also scrolls smoothly so the current word is always visible. Both the audio and the text continue playing until whichever one ends last.
What video format does it output?
The tool outputs WebM format, which is supported by Chrome, Firefox, and Edge. If you need MP4, you can convert the WebM using our free Video Converter tool.
How long does video generation take?
Generation time depends on your audio length and device speed. A 1-minute audio typically takes 1–3 minutes to render. The process runs entirely in your browser, so performance depends on your CPU.
💡Pro Tips: Getting the Best Results
- •Use a clean transcript or lyrics that match your audio exactly for best highlight sync.
- •Set the highlight interval close to your average words-per-second speaking rate for natural sync.
- •For fast rap or speech, set highlight speed to 0.3–0.5s. For slow ballads or poetry, try 2–3s.
- •After downloading, use the Convert Video tool to convert WebM to MP4 for wider compatibility.
