AI watermark remover that runs entirely in your browser
Upload an image or clip, let the detector find the watermark automatically, and download a clean file in seconds. Nothing is uploaded to a server — the whole pipeline runs locally on your machine.

Generative models stamp their output. Whether you are exporting a still from an image model or a short clip from a video model, the result usually carries a small semi-transparent mark burned into the bottom corner. That mark is not metadata you can strip with a command-line flag: it is baked into the pixels, blended over whatever content sits underneath it.
Most tools deal with that by hiding the problem. They blur the region, clone neighbouring pixels over it, or paint a solid block on top. The watermark disappears, but so does the underlying detail, and the patch is obvious the moment anyone looks closely or scrubs the timeline. An AI watermark remover should recover the original pixels instead of covering them.
This tool takes the mathematical route. Because a watermark is an alpha-blended overlay, the compositing operation that created it is invertible: if you know the mark's shape, position and per-pixel opacity, you can solve for the original colour underneath. The result is restoration rather than concealment — no soft rectangle, no smeared texture, no visible seam.
Why this approach beats blur-and-patch tools
Pixel-accurate recovery
Reverse alpha blending solves for the original colour value of each covered pixel instead of guessing a replacement, so edges, grain and gradients survive intact.
Automatic detection
The engine locates the watermark, its scale and its opacity profile on its own. There is no bounding box to drag and no per-file tuning to get right.
Nothing leaves your device
Processing happens in the browser tab. No upload, no server-side queue, no retention window, no third party holding a copy of your work.
No re-encoding penalty
Images are written back losslessly and video is re-muxed with the original stream settings, so you keep the resolution, frame rate and colour you started with.
Batch friendly
Queue up to twenty files, process them one after another and download everything as a single ZIP archive when the run finishes.
Free to use
Create an account to access the editor; there is no credit system and no watermark on the output.
How it works
1
Open the editor
Click Upload image to jump straight into the tool after signing in. Nothing installs and no permission prompt appears — it is a normal web page.
2
Add your file
Drag in a PNG, JPEG or WEBP image (up to 25 MB) or an MP4, WebM or MOV video (up to 100 MB). Multiple files can be queued in batch mode.
3
Let detection run
The engine scans the frame for the watermark signature, measures its size and alpha profile, and reports what it found before touching a pixel.
4
Review the comparison
A draggable before/after slider shows the original and the restored version at full resolution so you can confirm the recovery is clean.
5
Download the clean file
Save the result locally. For batch runs, export every finished file at once as a ZIP.
What an AI watermark actually is
A visible AI watermark is a small logo composited over the finished frame with partial transparency. The compositor takes the original pixel, the watermark's colour and an alpha value between zero and one, and mixes them: output = original × (1 − alpha) + mark × alpha. Where alpha is low the original shows through strongly; where alpha is high the mark dominates. That is why the logo looks like it is floating on the image rather than painted onto it.
Because the operation is a simple linear blend, it can be undone. Rearranged, the same equation gives original = (output − mark × alpha) ÷ (1 − alpha). The only unknowns are the mark's pixel values and its alpha map. Both are fixed for a given generator and a given watermark size, so they can be measured once and reused. That is exactly what this tool does: it matches the observed mark against a catalogue of known alpha maps, picks the best fit, and inverts the blend across the affected region.
The one place the maths breaks down is where alpha reaches 1.0 — fully opaque pixels carry no information about what was underneath. In practice AI watermarks stay semi-transparent almost everywhere, and the handful of near-opaque pixels are repaired from their immediate neighbourhood, which is a far smaller intervention than blurring the entire logo footprint.
Where blur, inpainting and clone tools fall short
Blurring is the cheapest option and the easiest to spot. A low-pass filter over the watermark region destroys high-frequency detail, so you end up with a soft rectangle that contrasts with the sharp content around it. On video it is even worse, because the blurred patch stays perfectly still while everything else moves, drawing the eye straight to it.
Generative inpainting is smarter but it invents content. The model looks at the surrounding pixels and hallucinates something plausible for the hole. On flat backgrounds that can be convincing; over a face, a texture or a line of architecture it produces detail that was never there. And because each frame is inpainted independently, video output flickers as the invented content changes shape between frames.
Clone-stamp workflows copy from elsewhere in the image. That preserves sharpness but duplicates texture, which repeats visibly on anything with structure. All three approaches share the same underlying flaw: they treat the watermark as missing data. It is not missing — it is attenuated, and attenuation is reversible.
Privacy, cost and the case for local processing
Every pixel is decoded, analysed and rewritten inside your browser tab using Canvas and WebCodecs. Your file never leaves the device, never touches a queue, and never gets stored on a server — which also means there is no upload wait and no file-retention policy to read.
That design has practical consequences beyond privacy. There is no rate limit, because there is no shared backend to protect. There is no file size cap imposed by an upload endpoint, only by your device's memory. There is no queue during busy periods. And the tool keeps working on an unreliable connection, because once the page has loaded, the network is no longer involved.
It also means the honest answer to 'what do you do with my files?' is 'we never see them'. For anyone working with client material, unreleased campaign assets or personal photographs, that distinction matters more than any privacy policy wording.
Getting the best results
A few habits improve output quality noticeably:
Work from the highest-quality export you have. A heavily compressed re-upload has already lost the fine detail the restoration would otherwise recover.
Avoid cropping or resizing before removal — the detector expects the watermark at its native scale relative to the frame.
Do not stack filters or colour grades first. Removing the watermark from the clean export and grading afterwards gives a cleaner result.
Check the before/after slider at 100% zoom rather than fitted to the window; that is where any residual artefact would show.
For video, keep the original container where possible so the audio track and timing pass through untouched.
Frequently asked questions
Is this AI watermark remover free?
Yes. An account is required to use the editor, but there is no credit balance or paid tier. Processing happens on your own hardware, so there is no per-file cost.
Does it work offline?
Once the page has loaded, yes. The removal engine and its alpha maps are bundled with the page, so processing continues even if your connection drops.
Which files are supported?
Images in PNG, JPEG and WEBP up to 25 MB, and video in MP4, WebM and MOV up to 100 MB. The tool is purpose-built for Gemini and Veo 3 style watermarks.
Will the output be re-compressed?
Images are written back as lossless PNG. Video is re-muxed rather than transcoded wherever possible, so resolution, frame rate and audio are preserved.
Are my files uploaded anywhere?
No. Decoding, detection, restoration and encoding all happen inside your browser tab. Nothing is transmitted and nothing is stored remotely.
Can I process several files at once?
Yes. Batch mode accepts up to twenty files, runs them sequentially with per-file progress, and lets you download the finished set as a single ZIP.
