Cover images
The cover fits inside a 1280 × 720 frame without stretching. Without a cover, the background is dark. The video lasts as long as your audio.
Questions
Is a cover image required?
No. Without an image, your audio plays over a plain dark frame. With a cover, the image stays visible for the whole video. Audio is encoded as AAC.
Do my files leave my device?
No. Processing stays in your browser. Download your result before closing or reloading this tab.
Is it free?
Yes. No account, payment or watermark.
Which browsers work best?
Use a recent Chrome, Edge, Firefox or Safari. For video, use short clips and keep this tab open while processing. Older devices may need smaller files.
