Add a Watermark to Video Online

Local · No uploads

Add a text watermark to your video, with control over font size, color, opacity, outline, shadow, and rotation — plus motion effects like scrolling up/down or side to side. Brand your original content, add a logo-style caption, or credit the source. The watermark is rendered locally; your video is never uploaded.

How to Add a Text Watermark to a Video

  1. 1

    Upload your video file

  2. 2

    Enter the watermark text and set the font size, color, opacity, and other styling

  3. 3

    Choose the watermark position, or pick a scrolling animation

  4. 4

    Click Process, then download the watermarked video

Common Uses

  • Add a copyright watermark to original videos to deter re-uploads
  • Brand your content with a logo-style text in the corner
  • Credit the source, creator, or channel

Things to Keep in Mind

  • Very long watermark text may run past the edge of the frame
  • Scrolling watermarks render frame by frame and take noticeably longer
  • Some fonts lack rare characters, which display as placeholders

How to Choose a Video Watermark Tool

  • vs. watermarking in a video editor: simple and instant — nothing to learn
  • vs. upload-based tools: your video never leaves your device
  • Nine-position placement plus scrolling and other motion effects

How Video Watermarks Work

  • Text watermarks are rendered by FFmpeg's drawtext filter: font, size, color, outline, shadow, position, and rotation are all filter parameters, baked in during a single encode.
  • The key word is "baked": the watermark becomes part of the picture, independent of any player or subtitle track — it survives playback, screenshots, and re-uploads. The flip side: it can't be removed later, so decide before you export.
  • Motion watermarks vary the position over time t (scrolling, bouncing, etc.), which requires computing the position for every frame — rendering takes much longer than a static watermark.

Video Watermark FAQ

Are animated watermarks supported?

Yes. Scroll up/down, side to side, diagonal movement, bouncing, and more — with adjustable speed.

Can I position the watermark freely?

Yes. Pick any of the nine grid positions or a scrolling mode, and drag it directly in the preview.

Can I adjust the watermark's opacity?

Yes, from 0 to 1 — plus outline, shadow, and rotation controls to keep the watermark from overwhelming the picture.

Is the watermark permanent?

Yes. It's rendered directly into the video frames, so it stays wherever the video goes — that's what makes it an identifier and a deterrent.

Does a watermark prevent theft?

It deters it: with your copyright or channel info burned into the picture, re-uploads still carry your mark.
