Video Compressor

Shrink MP4 / WebM by quality or target size.

Drop a video and compress it to a quality level or an exact file size — handy for email, chat, or upload limits. Re-encodes with FFmpeg compiled to WebAssembly, entirely in your browser; the file is never uploaded.

Processes your input on your device without uploading it. Libraries or models may need downloading. No site account is required.
