Compress a video to a smaller size

Shrink an MP4 or WebM for chat, email or the web — re-encoded entirely on your device, with nothing uploaded.

Video files balloon fast — a one-minute phone clip can be a hundred megabytes, far past what chat apps and email accept. This tool re-encodes the clip at a lower bitrate and, if you want, a smaller resolution, cutting the file down to a fraction of its size.

Pick the Small-file quality tier for the biggest saving, cap the size at 720p, and trim away the seconds you don't need — every step runs in your browser, so the video is never uploaded anywhere.

Perguntas frequentes

How do I compress a video without uploading it?

Open the video tool, drop in your MP4, WebM or MOV, choose the Small-file quality tier and convert. The re-encoding runs in your browser — the clip never leaves your device.

How much smaller will my video get?

The Small-file tier targets roughly half the bitrate of a typical phone recording, and capping the resolution at 720p shrinks it further — together they commonly cut a clip to a quarter of its size or less.

Will there be a watermark or a time limit?

No watermark and no arbitrary clip limit — it's free and unlimited. Long clips simply take about as long as the trimmed clip runs, because the browser re-encodes in real time.
