  3. Customize appearance — Adjust font, size, color, and opacity for text; or scale and opacity for image watermarks.
  4. Position your watermark — Click to place it in a corner, the center, or drag it to any custom position on the frame.
  5. Apply and download — Click Apply Watermark and save the branded video directly to your device.

Transparent PNG logos work best for image watermarks — the tool preserves the alpha channel so your logo appears cleanly on top of the video without a rectangular background box.

Frequently Asked Questions

Can I add a watermark to a video online without uploading it?

Yes — our free video watermark tool runs entirely in your browser. Select your video, configure your watermark, and download the result. Nothing is ever sent to a server.

Yes. Our image watermark mode fully supports PNG files with transparency (alpha channel). Upload your transparent logo PNG, position it, adjust the scale and opacity, and apply it cleanly over your video without any rectangle or background box.

Select the text watermark option, type your copyright notice (e.g., ”© 2026 YourName”), choose your preferred font size and color, set the position and opacity, then apply. The © symbol can be typed directly or pasted from your clipboard.

Does adding a watermark reduce video quality?

Adding a watermark requires re-encoding the video, which introduces a small amount of compression. With our default settings, the quality reduction is minimal and typically imperceptible. You can increase the output quality setting to minimize any visible difference from the original.
