Frequently Asked Questions
Which output formats are supported?
This tool outputs WebM video (VP8/VP9 via MediaRecorder) or WAV audio. These formats use browser-native codecs without any server-side processing.
Why does transcoding take a while?
The browser re-encodes the video in real-time using MediaRecorder. Transcoding speed depends on your device's hardware and the video's length and resolution.
Can I extract just the audio track?
Yes. Select WAV audio as the output format to extract and download the audio track from any supported video file.
Is my video uploaded to a server?
No. All transcoding uses browser-native APIs (Canvas Streams and MediaRecorder). Your video never leaves your device.
