High-fidelity video re-encoding. Reduce file sizes while preserving visual quality with browser-first, zero-upload compression logic.
Lower = Smaller file, more compression
All processing occurs locally within your browser. Your videos are never uploaded to any external server.

Video Compressor Pro utilizes adaptive bitrate encoding to reduce file sizes dramatically. By re-encoding video streams with a target bitrate derived from your quality settings, we eliminate redundant data without impacting the visual clarity of key frames and motion sequences.
Your video content never leaves your device. Unlike cloud-based video compressors that require uploading sensitive media to third-party servers, Zrubix processes everything locally using your browser's native MediaRecorder API. This is enterprise-grade privacy for personal use.
Downscaling resolution is one of the most effective methods to reduce video file size. Our tool allows you to select a target resolution (1080p, 720p, 480p, 360p), automatically maintaining the correct aspect ratio while performing high-fidelity downsampling on the fly.
In an era of 4K content and high-bitrate video, file sizes have ballooned beyond practical limits for many applications. Uploading a raw video to social media, embedding it in a presentation, or sending it via email can be a frustrating experience when the file is hundreds of megabytes. Zrubix Video Compressor Pro provides a high-fidelity solution, allowing you to reduce file sizes by up to 80% while retaining remarkable visual quality, all within seconds.
Why is browser-based compression superior? Traditional compression requires downloading and installing complex software like FFmpeg or Handbrake. Our local-first approach eliminates this friction. By leveraging the modern browser's native Canvas API and MediaRecorder, we perform real-time video re-encoding with zero dependencies. This makes Zrubix an instantly accessible tool for creators, marketers, and professionals on any device.
Performance is at the core of the Zrubix philosophy. Our tool draws each frame of your video onto an off-screen canvas, then captures this canvas as a new video stream using `captureStream()`. This stream is then fed into the MediaRecorder API, which encodes it using the high-efficiency VP8 codec. By adjusting the `videoBitsPerSecond` parameter based on your quality slider, we provide precise control over the final file size.
The result is a new WebM video file that is significantly smaller than the original. While there is a trade-off between quality and size, our default settings are calibrated to find the optimal balance for most use cases. For archival purposes, you can increase the quality; for quick shares, you can lower it to achieve dramatic size reductions. This is high-fidelity orchestration at your fingertips.
The Video Compressor Pro is a central component of the Zrubix media suite. After compressing your video, you might want to convert it to a GIF for a quick social media post or adjust its playback speed. Our suite of tools works in harmony, providing a complete, end-to-end workflow for all your video production needs. Experience the luxury of having professional-grade media tools accessible directly in your browser.
Trust Zrubix for your critical video optimizations. Our commitment to local-first, high-performance engineering ensures that your workflows are not only faster but also more secure. Compress, convert, and create with the surgical precision that only Zrubix can provide.
