Our free online video compressor uses modern WebCodecs technology to reduce video file sizes directly in your web browser. Unlike traditional online video compressors that upload your files to remote servers, our tool processes everything locally on your device. This means your videos remain completely private — they never leave your computer. The compressor supports all major video formats including MP4, MOV, AVI, WebM, and MKV, and outputs universally compatible MP4 files encoded with H.264. Whether you need to compress a video for Discord's 8MB file limit, shrink a video for email attachment, or reduce file size for faster uploading to social media platforms like TikTok, Instagram, and YouTube, our platform preset buttons calculate the optimal bitrate automatically. The compression algorithm balances file size reduction with visual quality preservation, offering three quality levels to suit your needs. Light compression preserves roughly 80% of the original quality and is ideal for sharing videos where visual fidelity matters. Medium compression achieves a good balance between size and quality for most everyday use cases. Heavy compression maximizes file size reduction for situations where smaller files are the priority, such as sending videos over limited bandwidth connections or meeting strict platform upload limits.
