Free video watermark remover · no upload
Remove a watermark, logo or text from a video
Mark the logo, caption or date stamp you want gone and an AI inpainting model (LaMa) paints the background back in, frame by frame. Free, no sign-up and no new watermark — everything runs on your device, so your video is never uploaded.
Fixed logos, text and date stamps are found and marked automatically — check the boxes before you start. Drag on the video to mark anything that was missed, and drag a box to move it. If a watermark moves, pause where it sits, mark it there and set that area's start and end time.
How to remove a watermark from a video
- Open your video. Drop an MP4, MOV or WebM file into the box above, or click to choose one. The file is read by your browser and never uploaded.
- Check the marked watermark. Fixed logos, text and date stamps are detected and boxed automatically. Otherwise drag a box over the mark yourself, leaving a small margin. Add a box for every mark. If a mark jumps to another corner, pause there, draw a new box and set its start and end time.
- Press “Remove watermark”. The LaMa model looks at the surrounding picture and paints plausible background into each box, frame by frame. Your graphics card does the work through WebGPU when the browser supports it.
- Compare and download. Drag across the video to compare the original with the cleaned version, then download the MP4. The original soundtrack is kept.
What you can remove from a video
- Logos and watermarks — an old brand logo, a channel bug or an editing-app watermark on your own footage.
- Text overlays and captions — hard-coded titles, subtitles or call-to-action text you want to replace.
- Date and time stamps — camera, phone or dashcam timestamps burned into the picture.
- Small distractions — a sensor dust spot, a stuck pixel or a small sticker in a fixed position.
Tips for the cleanest result
- Keep boxes tight but include soft shadows and glows. Use Edge padding instead of drawing large boxes.
- Calm backgrounds work best. Sky, walls, water and blurred backgrounds fill almost invisibly. Faces and fine text behind the mark are hard for any tool.
- Use “Every frame” for moving shots and the faster settings for tripod shots, where the background barely changes.
- Leave “Reduce flicker” on unless the camera moves fast. It blends neighbouring frames so the filled area stays steady.
Private by design
The model downloads once (about 208 MB) and stays in your browser's storage. Decoding, inpainting and encoding all happen on your device.
Fastest with WebGPU
Recent Chrome and Edge use your graphics card. Other browsers fall back to the CPU, which is much slower — use a lower frame setting there.
Video watermark removal — frequently asked questions
How do I remove a watermark from a video?
Choose your video, drag a box over the logo or text and press Remove watermark. The AI model fills in the area frame by frame. Compare the result with the original and download the cleaned MP4.
Does it find the watermark automatically?
Yes, for watermarks that stay in one place. The tool samples frames across the video and looks for edges that never change while the picture behind them does — that is what a burned-in logo, text or date stamp looks like. It works best when the camera or scene moves. On a locked-off shot where nothing changes, or for marks that jump around, mark them by hand.
Is my video uploaded to a server?
No. The model is downloaded once and stored in your browser. Your video never leaves your device.
Why is the first run slow?
The LaMa model is about 208 MB and is downloaded on first use. Later visits load it from your browser's storage. Processing speed depends on your device: with WebGPU a short clip takes about a minute, without it several minutes.
Is the video watermark remover free?
Yes. There is no sign-up, no limit on the number of videos and no watermark added to the result. Because everything runs in your browser, there is no server cost to pass on.
Can I remove text, subtitles or a date stamp from a video?
Yes. Anything burned into the picture works the same way: channel logos, text overlays, hard-coded captions, camera or dashcam date and time stamps. Mark the area and the model paints in the background.
Which video formats are supported?
Any video your browser can decode, usually MP4 (H.264, H.265), MOV and WebM (VP9, AV1). The result is saved as an MP4 with the original audio.
Does it work on a phone?
It works in modern mobile browsers, but the 208 MB model download and the processing are heavy. A laptop or desktop with Chrome or Edge is much faster.
What if the watermark moves?
Mark one area per position and set each area's start and end time to when the watermark sits there.
Why do I see a slight shimmer in the filled area?
Each frame is filled on its own, so busy or moving backgrounds can flicker a little. Keep Reduce flicker on, and keep areas tight around the watermark.
Can I use it on any video?
Use it on videos you own or have permission to edit. Removing someone else's watermark or copyright notice can break their rights and the law.
