Privacy note

No server upload for this workspace

This video workspace uses browser APIs and FFmpeg/WASM for private preview, frame capture, trimming, muting, GIF creation, and audio extraction. For very large videos, a future secure VPS processing option can add temporary upload with immediate deletion after conversion.

Files stay local

The selected file is read from the visitor device and is not uploaded by this page.
