Frequently asked

Does my video get uploaded anywhere? +

No. Everything runs in your browser with WebCodecs. Your video is never sent to a server and nothing leaves your device.

Which formats can I convert between? +

Drop almost any video and export to MP4 or MOV (H.264), MKV (H.264), or WEBM (VP9 plus Opus). MP4 is the safest pick for phones, TVs, and editors.

Why does conversion take a moment? +

When the source codec differs from the target, the video gets decoded and re-encoded frame by frame. Longer or higher-resolution clips take proportionally longer.
