Video Standards & Simple Playback Guide

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.

视频缩放器 常见问题
会把视频放大吗？
默认不会。如果您选的尺寸大于源视频，工具会保持原始尺寸，除非您明确开启放大。
缩放会裁剪视频吗？
不会。缩放是整体缩放整个画面。要去掉边缘或改构图，请用视频裁剪器。
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.
