Video files too big to share on chat, cloud drives or platforms? TutuCut's online video compressor works right in your browser, shrinking MP4, MOV, WebM and more for easier sharing and storage.

Compression runs entirely locally — videos aren't uploaded, so it's more private; adjust resolution, bitrate and frame rate to balance quality against size.

Export in one click when done — no watermark, no signup, works on phone and desktop.

FAQ

Will the quality drop after compression?

You control it. A modest bitrate cut shrinks the file noticeably with almost no visible difference; pushing for a tiny file brings perceptible loss — balance as needed.

Will my video be uploaded to a server?

No. TutuCut does editing, compression and conversion locally in your browser — videos never leave your device. Only when you actively sign in and choose cloud save / 4K cloud rendering is a project uploaded to your account.

How large a video is supported?

Since it's local, the main limit is your device memory; typical phone videos from a few hundred MB to several GB compress fine. Use a computer for very large files.

Do I need to download or install anything?

No. Open the page and go — no install, no signup, on both phone and desktop browsers.
