How it works

Three steps. No signup. Nothing leaves your browser.

1
Drop your video
MP4, MOV, WebM, or MKV. Your file stays on your device the whole time.
2
Pick a quality
Low for the smallest file, Medium for social posts, High to keep it close to the original.
3
Download the MP4
Get a smaller, social-ready MP4 in seconds. Compress as many videos as you want.

Is this video compressor really free?: Yes. No signup, no watermarks, no upload caps. Use it as much as you want.
Does my video get uploaded anywhere?: No. Compression happens entirely in your browser using your device's hardware video encoder. Nothing leaves your computer.
What video formats are supported?: MP4, MOV, WebM, and MKV. Output is always MP4 (H.264) for maximum compatibility with Instagram, TikTok, LinkedIn, and email.
How small will the output be?: Depends on the source. The Low preset typically shrinks files by 80–95%. Medium hits a balance most people use for social. High keeps quality close to the original while still saving space.
Will it work on my iPhone or iPad?: Safari 16.4 and later supports the WebCodecs API used here. Older Safari versions won't work. Switch to Chrome or Edge if you hit a compatibility message.
Does it work for Instagram, TikTok, or Reels?: Yes. The output is a standard MP4 that any social platform accepts. Pick Medium for the best size/quality trade-off.
