  • Text and logo together, single, tiled, or moving.
  • Your last settings are remembered on this device.
  • The audio is copied untouched.
🎯

About Video Watermark

Watermark video in the browserPrivate, exact video watermarkingMark your videos before they travel

Text or logo

Type a line of text and choose its font, colour, outline, and shadow, or use your own logo as a PNG, JPEG, WebP, or SVG image.

Size, opacity, and rotation apply to both, so the mark can be bold or barely there.

Placed exactly

Pick one of nine positions with a margin from the edge, or drag the mark on the preview to place it anywhere; it always stays inside the frame.

Tiled repeats the mark across the whole frame, with adjustable spacing and an offset-row pattern, using the same layout as the Image Watermark.

Local processing and clear limits

Every frame is drawn and re-encoded on your device by the browser's own encoder, so nothing is uploaded. The audio is copied as it is.

Desktop browsers handle files up to 2 GB, phones and tablets up to 250 MB. Long or 4K files take a while, and the export shows how long is left.

FAQ

Common questions.

Have more questions? Reach out via our contact page and we will respond within 24 hours.

Is my video uploaded?

No. The video is read, marked, and encoded in your browser, and the file never leaves your device.

Can I use my logo?

Yes. Choose a PNG, JPEG, WebP, or SVG image; transparent PNGs keep their transparency.

Where can the watermark go?

In any of nine positions with an adjustable margin, anywhere you drag it on the preview, or tiled across the whole frame.

Does the watermark appear for the whole video?

By default, yes: it is drawn on every frame from start to end. You can also show it only between two times, with an optional fade in and out.

Will the watermark look the same as the preview?

Yes. The preview and the export are drawn by the same code, at the same position, size, opacity, and rotation.

Is the audio changed?

No. The audio is copied untouched.
