MKV 转 MP4 转换器 常见问题
为什么我的 MKV 播不了？
很多智能电视、手机浏览器和播放器原生不支持 MKV 容器，转成 MP4 就解决了。
我的视频会被上传到服务器吗？
不会。本工具在您的浏览器本地处理文件，BeYourTools 不会上传、存储视频，也不会把媒体发给处理 API。
Does processing reduce the quality or resolution of my original video?
Trimming, cutting, and frame extraction keep your original video resolution and picture clarity. Our compressor tool lets you choose how much file size to shave off while keeping your picture sharp.
Are my personal videos uploaded to or viewable by anyone else?
No. All video editing happens right in your browser memory. Your files are never sent to our servers or saved anywhere online. Everything stays safe on your own device.
