Frequently asked questions
Can I merge videos with different formats?
Yes. Clips in different formats and sizes are brought to one format and size — older ones like AVI or WMV are converted as you add them.
Can I change the order of the clips?
Yes. Drag the clips into any order (or use the move buttons), trim each one with the handles, and choose a straight cut or a fade between them.
Is my video uploaded to a server?
No. Cutlia processes your video directly in your browser using WebAssembly and your device's hardware. The file never leaves your computer or phone, so it stays completely private.
Is it really free?
Yes. Cutlia is free to use with no account, no trial and no watermark on your export. The site is paid for by the ads on it, and your files never leave your device.
