常见问题
Does converting change the video quality?
It re-encodes to H.264, which involves a small quality trade-off like any re-compression, but at the default settings it is visually close to the source. The upside is a file that plays everywhere MP4 is expected.
Is the video uploaded?
No. The transcode runs with WebCodecs on your own device, so the video never leaves the browser — no account, no quota, no size limit. Chrome, Edge and Firefox work best; Safari’s video encoding is more limited.
