Are my video files uploaded to any external server?

No. All video decoding, downsampling, and stream re-encoding execute 100% locally inside your web browser using HTML5 Video and MediaRecorder APIs. Your video files never leave your computer.

Does this tool add a watermark to my compressed video?

No. All tools on 360tools.me are 100% free and never add watermarks, timestamps, or promotional branding to your compressed media.
