Video Standards & Simple Playback Guide
Working with video requires balancing file size with clear playback. Using Video Cropper helps you prepare clean video clips that play smoothly on any phone, tablet, or computer. Whether you need smaller clips for email or fast-loading videos for your website, our tool gets the job done quickly.
Fast Browser Processing
All video slicing, frame capture, and encoding run directly inside your browser. Your computer or phone handles the work locally, so your large video files never upload over the web.
Everyday Compatibility
Your saved clips keep standard screen shapes, true colors, and clean sound. They open immediately in Apple QuickTime, Windows Media Player, Chrome, and Safari without extra plugins.
视频裁剪器 常见问题
能做竖屏视频吗？
能。选择 9:16 预设，把裁剪框放到主体上即可。
裁剪会拉伸视频吗？
不会。裁剪是去掉所选矩形之外的像素，不会扭曲所选区域。
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.
