What is lossless remux?

Lossless remux changes the container format without re-encoding the video. This is much faster and preserves original quality, but only works when the codecs are compatible with the target format.

Will conversion reduce video quality?

Lossless remux preserves original quality. Full re-encode may reduce quality depending on your settings. Use higher quality settings to minimize quality loss.

Is there a file size limit?

Processing runs in your browser, so there is no server-side limit. Large videos may take longer to process depending on your device capabilities.

Can I convert videos for specific platforms?

Yes, you can choose output formats optimized for different platforms. MP4 works for most platforms, WebM is ideal for web, and MOV is common for Apple devices.
