视频缩略图生成器 常见问题
为什么这个工具用 Canvas？
单帧抓取时，浏览器 video 元素加 Canvas API 比加载 FFmpeg 更快更轻。
视频无法预览怎么办？
浏览器可能不支持源编码。先转成 MP4 再生成缩略图。
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.
