About MP4 Video Compression Technology
MP4 (MPEG-4 Part 14) is the standard video format for web, mobile, and streaming platforms. Large MP4 files can be difficult to share or upload. Our video compression tool uses advanced encoding techniques to reduce file size by adjusting bitrate, resolution, and codec settings while maintaining the best possible visual quality. All processing happens locally in your browser using WebAssembly and FFmpeg.js.
