Frequently asked questions
Can I play WMV on a Mac?
Not with QuickTime or the Photos app. Converting to MP4 makes it play there, on iPhones and on most TVs.
Will my WMV lose quality?
It's re-encoded once, to H.264, at a bitrate meant to look like the original.
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.
