How to Add a Watermark to a Video Online for Free

  1. Load your video

    Drop a video file onto the page or click Select Video. MP4, MOV, MKV, WebM and other common formats are supported. A preview of the video loads immediately.

  2. Choose a text or image watermark

    Pick Text to type a name, URL or copyright line and choose a color, or pick Image to upload a PNG, JPEG, WebP or SVG logo. Transparent PNGs composite cleanly on top of the video.

  3. Position, size and opacity

    Select one of nine positions from the grid - corners, edges, or center. Adjust size, opacity and edge margin with the sliders, or switch on Tile across video to repeat the watermark on a grid for anti-piracy protection. The preview updates live.

  4. Apply and download

    Click Apply Watermark. The watermark is baked into every frame of the video. When processing completes, download the watermarked file.

Text vs Image Watermarks

A text watermark is quickest - type the text you want and pick a color. It is ideal for names, URLs, channel handles and copyright lines. An image watermark lets you use a transparent PNG logo, a signature, or any brand mark. Both are composited at the resolution of your source video, so the watermark stays sharp at any size. The output is re-encoded at high quality with the watermark baked into every frame, so it cannot be removed by re-encoding or trimming.

Frequently Asked Questions

How do I add a watermark to a video online for free?

Drop or select your video file on this page. Choose Text to type a watermark or Image to upload a logo. Pick a position, adjust opacity and size, then click Apply Watermark. The watermarked file downloads when processing finishes. Everything runs in your browser - no upload, no signup, no cost.

Can I use a transparent PNG logo as the watermark?

Yes. PNG, WebP and SVG images preserve transparency so your logo composites cleanly over the video. JPEG images are also supported but will show as a solid rectangle since JPEG has no alpha channel.

Where can I place the watermark?

The position grid offers nine presets: the four corners, the four edge midpoints, and the center. Use the edge margin slider to control how far from the edges the watermark sits. Switch on Tile across video to repeat the watermark on a grid over the whole frame.

Does this add a VidShift watermark to my video?

No. VidShift never adds its own watermark. Only the watermark you choose is added - and only if you add one. If you leave the text empty and pick no image, nothing changes.

Will the watermark be permanent in the output file?

Yes. The watermark is rendered into every frame when the video is re-encoded, so it cannot be removed by changing containers, trimming, or re-encoding again. This is the intended behaviour for branding and copyright protection.

What video formats can I watermark?

VidShift supports all common video formats as input: MP4, MOV, MKV, WebM, OGV, M4V, and MPEG-TS. You can export the watermarked result as MP4, WebM or MKV.

Will watermarking reduce video quality?

Watermarking requires re-encoding the video so that the watermark is baked into every frame. VidShift re-encodes at high quality, so any difference from the original is typically not noticeable. If you want a smaller file afterwards, you can compress the video.

Are my files uploaded to a server?

No. Your files never leave your device. VidShift has no backend servers that receive or store your media. All processing runs locally in your browser using WebAssembly, ensuring complete privacy. The tool even works offline after your first visit.
