Reconstruction, not blur
A MI-GAN inpainting model paints plausible background into the selection instead of smearing the watermark's own pixels.

Remove Watermarks from Video with AI
ClearMark AI rebuilds the area behind a logo, watermark or text with AI inpainting — entirely inside your browser. No upload, no signup, and no blurry patch left behind.

Any video format, any size (supported by your browser)
or drop a file here · checking your device
Videos, frames and selections stay on your device. Nothing is uploaded or stored.
How it works
Three steps, all of them local. The only thing downloaded is the inpainting model, once.
1. Choose your video
Pick or drop any file your browser can decode. It opens locally — nothing is uploaded, so even a large clip starts instantly.
2. Draw over the watermark
Pause on a frame and drag a box around the logo or text. Because static watermarks stay put, the same box is used for every frame.
3. Let the AI rebuild it
An inpainting network reconstructs the covered area from the surrounding pixels, then the frames are re-encoded to MP4 with your original audio.
Built for clean results
Nothing leaves your device
Decoding, inference and encoding all happen in your browser. There is no upload endpoint, no queue and no stored copy.
WebGPU with a safe fallback
Desktops use WebGPU when available and fall back to WebAssembly automatically. Phones switch to a low-memory profile.
Original resolution and audio
Output keeps your resolution and frame rate wherever the encoder supports it, and copies the original audio track untouched.
Flicker-aware frames
Each rebuilt region is lightly blended with the previous frame inside the mask only, so the patch does not shimmer during playback.
Honest progress
Every step reports real state — model download size, frame counts, elapsed time and an ETA. If the model cannot run, you get an error, never a fake result.
Blur versus reconstruction
What a blur tool leaves
The logo's pixels are still there, just smeared. The eye reads the soft rectangle immediately, and it moves with every camera pan.
What ClearMark AI produces
The region is rebuilt from the surrounding image with a feathered, colour-matched seam, so there is no soft box and no visible edge.
When people reach for it
Stock footage you licensed
You bought the clean licence but only have the preview file on hand while the download finishes. Rebuild the preview mark on footage you are entitled to use.
Your own old exports
An old export carries a studio bug or an outdated channel logo you no longer use. Clear it without re-rendering the whole project.
Client handovers
A client approves a draft that still carries your review watermark. Remove it from the draft you produced before delivery.
Course and demo recordings
Screen recordings often pick up trial-software badges and timestamps in a fixed corner — a perfect case for static reconstruction.
Use ClearMark AI only on videos you own or have the rights to edit. Removing someone else's watermark to republish their footage is very likely copyright infringement.
Privacy and security
No upload path
There is no server that receives video. The file is read through a local object URL and decoded in a Web Worker on your machine.
No storage
Frames, masks and the finished file live in memory only. Closing the tab clears everything; only the cached model file remains.
No content analytics
Your video, your selection and your filenames are never sent to any analytics or logging service.

Frequently asked questions
Is ClearMark AI really free to use?
Yes. There is no signup and no watermark on the result. Processing time and practical limits depend on your device because all computing happens locally.
Does my video get uploaded anywhere?
No. Your file is opened with a local object URL and decoded frame by frame inside your browser. The video, the frames and the selection box never leave your device and nothing is stored after you close the tab.
How is this different from blurring the watermark?
Blur keeps the watermark's pixels and smears them. ClearMark AI runs an inpainting neural network that rebuilds the hidden area from the surrounding image, so you get plausible background instead of a smudge.
Which video formats can I use?
Anything your browser can decode, which usually means MP4/H.264, WebM/VP8/VP9 and often AV1. Some devices cannot decode HEVC (H.265) or ProRes MOV files; in that case convert the file to MP4 first.
Does the output keep the original resolution, frame rate and audio?
Yes, whenever your browser's encoder supports that resolution. The original audio track is copied over untouched. If a size is rejected by the encoder, the tool scales down to the largest supported size and tells you.
Will it work on my phone?
On recent iPhones and Android phones, yes. Phones use a smaller 256 px crop and a single processing thread to stay inside their memory limits, so expect slower processing than on a laptop.
How long does processing take?
It depends on your hardware, the video length and the size of the selection. A short clip on a desktop with WebGPU takes a couple of minutes; a long clip on a phone can take considerably longer. The tab must stay open.
Can it remove a moving or animated watermark?
ClearMark AI is built for static watermarks that stay in one place. For a moving logo, select a box large enough to cover its whole path, which will reconstruct more of the frame.
Is it legal to remove a watermark?
Only remove watermarks from footage you own or have written permission to edit. Removing a watermark from someone else's video to reuse it is very likely copyright infringement. See our disclaimer for details.
Why does the model need to download 28 MB?
The inpainting network runs locally, so it has to reach your device once. It is cached by your browser afterwards, so later videos start immediately.
Ready to clean up your footage?
Free, private and instant — the video never leaves your device.
