What “free” actually means here
Most tools in this category are free in a specific and limited sense: free up to a few images, then pay, or free if you create an account, or free if you accept a licence to your uploads. Each of those is a small sentence in the pricing page rather than in the product.
This one is free because of how the work is done. Processing runs in your browser through WebAssembly, so the cost of serving a user is paid before you arrive. There is no per-user compute bill to recover, therefore no quota, no credit counter and no reason to ask for an account.
- No account, no email, no password.
- No credit counter and no daily limit.
- No trial that expires and no premium tier.
- No upload, so nothing to store and nothing to leak.
- No watermark added to your output, which is the usual catch.
How to verify the no-upload claim yourself
Privacy claims are cheap to make and easy to fake, so this one is testable in about thirty seconds. Load this page, then turn off your network connection, and process a file. The tool still works, because nothing was being fetched. A tool that uploads your file stops working the moment the connection drops.
You can also open the browser network panel and watch. A tool that processes locally makes no request carrying your image. That is the whole mechanism, not a setting.
What “no blur” means
A visible watermark is not an erasure. It is a semi-transparent graphic blended on top of the image, so the original pixels are still underneath. That makes the operation reversible by arithmetic:
Solve it backwards and the original is recovered exactly. Tools built on generative inpainting cannot do this, because they do not know what was under the mark. They infer a plausible continuation of the surrounding texture, and inference is visibly wrong wherever the image has fine detail. The comparison is in how to remove a watermark without blur, and the detection problem is in watermark geometry detection.
Which files it works on
| Input | Handled | Notes |
|---|---|---|
| Gemini / Nano Banana images | Yes | PNG, JPEG, WebP up to 20 MB |
| Veo / Veo 3 videos | Yes | MP4 and WebM, frame-by-frame |
| Sora output | No | Not supported by this tool |
| Invisible SynthID signal | No | Different system, see below |
| Re-encoded or screenshotted files | Unreliable | Original export required |
The last row is the one that catches people out. If a file has been screenshotted, re-saved or uploaded through a messaging app, the visible mark is still there but the recoverable signal underneath it is not, and no method can restore what an earlier encode discarded. Use the original download.

Image Studio for still images, Video Studio for video. Both are the same engine with a different decoder, and neither asks you to do anything before your first file.
Why free tools usually are not free
Worth understanding, because the reason explains everything else on this page. A hosted tool has a per-user cost: bandwidth for the upload, CPU time for the inference, and storage if the file is kept. That cost has to be recovered somehow, and there are only three places to get it: from the user, from the advertiser, or from the margin.
Charging the user is the obvious route, which is why the free tier usually stops after a few files. Recovering it from advertising is the second, which is why so many “free” removers carry pop-unders and social bars — the page has to earn its keep before you have seen a result. Squeezing the margin is the third, and it is the one that produces a tool that is slow and degraded on the free tier, because the cheap path is the one the non-paying users get.
This tool avoids all three by not having a server in the path. The processing cost is paid by the device you are already using, which is why the limits here are your device’s limits and not a quota.
What this does not do
It does not remove invisible provenance signals such as Google’s SynthID. That is a different system embedded in the content rather than layered on it, and the reasoning is set out on the SynthID page. A tool advertising removal of both is describing something that does not exist.
And a note on permission, since a tool that removes marks will always attract that question: whether a given use is lawful is separate from whether the method works. The sourced legal analysis covers the statutes and the specific policy clauses, including Google’s Terms of Service, which prohibit removing their branding even where you hold the rights to the underlying media.
