Free Online Video Compressor — Reduce File Size in Your Browser
Large video files are a problem. They eat up storage, take forever to upload, and get rejected by email and social media platforms. A video compressor reduces the file size by re-encoding the video at a lower bitrate, resolution, or both. The result is a smaller file that still looks good enough for most purposes.
This free Video Compressor works entirely in your browser. You do not need to upload your video to any server. Your files never leave your device. The tool uses the browser's native Canvas and MediaRecorder API to re-encode the video at a lower bitrate. You can choose from three quality levels and four resolution options. The output is a WebM file that plays in all modern browsers.
The compression process is simple. Select a video file, choose your quality and resolution settings, and click Compress. A progress bar shows you exactly where the process is. When it finishes, you see a side-by-side comparison of the original and compressed file sizes, along with the percentage saved. You can preview the compressed video right in the browser and download it with one click.
Video compression is essential for content creators, social media managers, developers, and anyone who works with video regularly. Whether you need to compress a video for email, WhatsApp, Discord, or your website, this tool does it without installing any software, without creating an account, and without any file size limits beyond what your browser can handle.
Features
100% Browser-Based
All processing happens in your browser using native APIs. No server uploads. No third-party services. Your videos stay private.
3 Quality Levels
Choose High (75%), Medium (50%), or Low (25%) quality. Each level reduces the bitrate proportionally for predictable file size reduction.
4 Resolution Options
Keep the original resolution or downscale to 720p, 480p, or 360p. Downscaling combined with bitrate reduction gives the biggest savings.
Real-Time Progress
A live progress bar shows compression progress in real time. You can see exactly how far along the process is.
Size Comparison
After compression, see the original size, compressed size, and percentage saved in a clear three-column layout.
