About Video Watermark Adder

The Video Watermark Adder is a completely free, browser-based video editor for adding text or image watermarks directly to video frames. Perfect for YouTube and social media copyright protection, corporate logo branding, confidential labels on internal footage, and more—no software installation required. In text watermark mode, customize text content, font size (8–200px), font family (6 options: Sans-serif, Serif, Monospace, Cursive, Fantasy, System-ui), text color, and opacity (0–100%). In image watermark mode, load PNG or JPG logos and adjust scale (10–100%) and opacity. Choose from 9 placement positions: top-left, top-center, top-right, middle-left, center, middle-right, bottom-left, bottom-center, bottom-right. Real-time canvas preview lets you fine-tune settings before processing.

To optimize processing time and file size, select from three quality presets (Low/Medium/High). Low quality accelerates processing for resource-constrained environments, Medium is the balanced default, and High delivers maximum quality output. All processing happens entirely in your browser using HTML5 Canvas, MediaRecorder, and Web Audio APIs—your video never uploads to any server. Safe for confidential corporate videos with zero data leakage risk.

How to use Video Watermark Adder

  1. Drag and drop a video file (MP4, MOV, WebM, etc.) into the drop zone, or click to select from your device.
  2. Choose an output quality preset: Low for fast processing, Medium for balanced results (default), or High for maximum quality.
  3. Select watermark type: Text or Image. For text, set content, font (6 families), size, color, and opacity. For image, upload a logo and adjust scale and opacity.
  4. Pick a placement position from the 3x3 grid. Use the seek bar to preview multiple frames and verify the watermark appearance on canvas.
  5. Click "Add Watermark & Save." Once processing completes, download your watermarked video file.
