Video Standards & Simple Playback Guide
Working with video requires balancing file size with clear playback. Using Video Compressor 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.

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.
视频压缩器 常见问题
文件一定会变小吗？
通常会，但不总是。已优化过的视频如果选了高质量预设，偶尔会变大。
CRF 是什么意思？
CRF 控制视觉画质。值越低保留细节越多、文件越大；值越高压缩越激进。
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.
