Frequently Asked Questions

What video formats are supported?

The video tools support common web formats including MP4 (H.264), WebM, and OGV. MP4 is recommended for broadest compatibility across devices and browsers.

Are my videos uploaded to a server for processing?

No. All video processing uses your browser's built-in media APIs and WebAssembly. Your video files never leave your device — privacy is guaranteed by the architecture, not just a policy.

Is there a duration or file size limit for video tools?

For best performance, we recommend videos under 500MB and 30 minutes in duration. Longer or larger files may be slow to process depending on your device's hardware capabilities.
