Add a watermark to videos and photos
Stamp text or your PNG logo on a video or a batch of photos: any corner, any opacity, or tiled diagonally across the frame. Photos download as a ZIP.
How it works
- Pick text or a logo, then the corner, size, margin and opacity. The preview updates as you drag.
- Videos are decoded and encoded again on your device with WebCodecs, with the watermark drawn on every frame; audio is kept.
- Photos keep their format (JPG stays JPG, PNG stays PNG) and their full resolution.
Questions
Does tiling protect better than a corner logo?
Yes. A corner mark can be cropped off in seconds; a tiled pattern across the frame is much harder to remove.
Are my photos uploaded?
No. Everything happens in this tab. You can switch off Wi-Fi after the page loads and it still works.
How many photos at once?
As many as your device memory allows; hundreds of phone photos are fine on a laptop.
