FAQ

Can I turn landscape into vertical?

Yes. Choose the 9:16 vertical ratio and adjust the subject's position.

Does cropping reduce sharpness?

Cropping keeps a region of the frame, so the kept area's sharpness is unchanged; enlarging a small area does lose some detail.

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.

Do I need to download or install anything?

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