FAQ - Video Overlay

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

Our free video overlay tool allows you to add watermarks, logos, and image overlays to videos directly in your browser. Simply upload your video, add your overlay image, position it where you want, and the tool applies it automatically. All processing runs locally – no uploads to servers, completely free and unlimited.

Can I add a logo or watermark to my video?

Yes! Our video overlay tool is perfect for adding logos, watermarks, or any image overlay to your videos. You can position the overlay anywhere on the video, adjust its size and transparency, and preview the result before applying. Great for branding your content or protecting your videos.

Is the video overlay tool free?

Yes, our video overlay tool is 100% free. There are no hidden costs, no registration required, and no limit on the number of videos you can process. Add overlays to as many videos as you want – completely free.

Are my videos uploaded when adding overlays?

No! All video processing happens 100% locally in your browser. Your videos never leave your device – maximum privacy and security guaranteed. Processing uses WebAssembly technology directly on your computer, so your files stay completely private.

What image formats can I use for overlays?

You can use PNG, JPG, WebP, and GIF images as overlays. PNG images with transparency work best for logos and watermarks, as the transparent areas will show the video behind them.

Can I adjust the overlay position and size?

Yes! Our tool offers complete control over your overlay. Choose from preset positions (corners, center, edges) or set a custom position. You can also adjust the scale to make the overlay larger or smaller, and set the opacity to make it more or less transparent.

Will adding an overlay reduce video quality?

The video is re-encoded when applying the overlay, but we use high-quality settings to maintain excellent visual quality. The overlay itself is applied at the resolution you provide, so using a high-resolution overlay image will give the best results.

How long does it take to apply an overlay?

Processing time depends on your video's length, resolution, and your device's performance. A typical 5-minute video can be processed in about 1-3 minutes on modern devices. Since everything runs locally, there are no upload or download waiting times.

What video formats are supported?

Our video overlay tool supports all common video formats including MP4, WebM, MKV, MOV, AVI and more. The output is MP4 (H.264) for maximum compatibility across all devices and platforms.
