About 视频压缩器
OptiPix Video Compressor lets you reduce video file sizes without uploading them to any server. Using the browser's built-in MediaRecorder API combined with Canvas-based frame processing, videos are re-encoded at lower bitrates while maintaining reasonable visual quality. This is especially useful for compressing videos before sharing on WhatsApp, email, or other platforms with strict file size limits. The compressor supports MP4, WebM, and MOV input formats and outputs optimized WebM or MP4 files. You can adjust the target quality to find the right balance between file size and visual fidelity. Since everything runs in your browser, there are no upload wait times, no file size restrictions from servers, and complete privacy — your videos stay on your device throughout the entire process. Processing speed depends on your device's hardware, with modern computers handling most videos quickly.
How It Works
The compressor uses the browser's MediaRecorder API to re-encode video frames at a lower bitrate. Each frame is drawn onto a Canvas element and re-captured as part of a new media stream, which is then encoded into the output format at your specified quality level.
