What Is a Video Watermark?

A video watermark is a text or logo overlaid on your footage to claim ownership, prevent piracy, or promote a brand. This free tool renders the watermark as a transparent PNG and composites it onto every frame with FFmpeg, entirely in your browser.

How to Use

Upload a video, then choose a text or image watermark. Adjust the font size or logo size, color, opacity and position, then click “Add Watermark”. The processed video is encoded locally and can be downloaded instantly.

Tips

  • Use a semi-transparent logo for subtle branding
  • Keep text short so it stays readable on small screens
  • For square videos pick a smaller font size percentage
