Video Compressor

Free video compressor — reduce MP4 or WebM file size in your browser. Choose quality presets, preview savings, and download. Private, no upload, no signup.

Compression runs locally. Your video never uploads to our servers.

Uses ffmpeg.wasm in your tab — slower than desktop HandBrake, and huge 4K files can exhaust RAM. HEVC/MOV may fail depending on your browser. This re-encodes video (not lossless, not a rename-only remux).

Compress a video privately

Upload an MP4 or WebM, pick a quality preset, and download a smaller file — all in your browser. For animated GIF export, use Video to GIF Converter instead.
