Common questions.
Are my files uploaded anywhere?
No. All tools process video directly in your browser. Your files never touch a server.
What browsers are supported?
Chrome 94+, Edge 94+, and Safari 16.4+. Firefox has limited support. The WebCodecs API is required for hardware-accelerated encoding.
Is there a file size limit?
There is no hard limit, but processing very large files may use significant memory. For files over 500MB, we recommend using Cutsio's server-side processing.
Are these tools free?
Yes. All browser-based tools are free with no account required and no watermark. Cutsio's server-side AI features require a subscription.
What formats are supported?
MP4, MOV, WebM, MKV, and common audio/video formats are supported depending on the tool. Outputs are designed for broad compatibility.
