REMOVE LOGO FROM IMAGE

Remove a logo overlay and keep what was underneath

Corner logos from AI generators are alpha-blended, not painted on. This tool inverts the blend and gives you the underlying image back — locally, in your browser.

A logo burned into the corner of an exported image behaves differently from a sticker. It is composited with partial transparency, which is why you can usually make out the shapes behind it. That transparency is the reason a good removal is possible at all — and the reason a bad removal is so easy to spot.

Painting a box over the logo, blurring it, or cloning texture across it all leave a signature. The treated region has different noise characteristics from its surroundings, different sharpness, and often a slightly different colour cast. Even a casual viewer registers that something has been done to that corner.

Solving for the underlying pixels avoids all of that. The correction is applied per pixel, weighted by how opaque the logo was at that point, so it fades to nothing at the edges and leaves the surrounding image completely untouched.

Why the result holds up under scrutiny

No rectangle artefact

The correction follows the logo's actual alpha shape rather than a bounding box, so there is no hard edge where treatment stops.

Texture continuity

Noise and grain under the logo are preserved, so the treated area matches the rest of the frame at pixel level.

Handles complex backgrounds

Because the original values are recovered rather than invented, logos sitting over faces, text or detailed scenery come away cleanly.

Automatic variant matching

Different generators and export sizes produce different logo scales; the engine tests candidates and picks the one that best explains your pixels.

Lossless export

Results are written as PNG at the original resolution, so nothing is downsampled or re-compressed.

Runs on your device

No upload step, so no waiting, no size limits imposed by a server, and no copy of your image sitting in someone's storage bucket.

Overlay logos versus printed logos

It is worth being precise about what can and cannot be recovered. An overlay logo is composited onto a finished image with an alpha channel — the generator renders the picture, then blends its mark on top. The original pixel data is attenuated but still present, so it can be solved for.

A printed or in-scene logo is different. If a brand mark appears on a sign, a shirt or a billboard inside the photographed scene, it is part of the image content, not an overlay. There are no original pixels behind it to recover, and removing it requires generative fill that invents replacement content. This tool does the first job, not the second.

In practice, the corner marks that generative image and video models apply to their output are always overlays. That is what makes reversal viable and why the results look untouched rather than retouched.

The detection stage matters as much as the maths

Inverting an alpha blend is trivial arithmetic if you already know the alpha map. The hard part is knowing it. Get the position wrong by two pixels and the correction lands off-centre, leaving a ghost on one side and an over-correction on the other. Get the scale wrong and the whole footprint is subtly miscorrected.

So the engine spends most of its effort on identification. It searches the expected regions for a logo signature, estimates the footprint, generates candidate placements at several scales and variants, applies a trial correction for each, and scores the outcome on how well the treated region blends with its surroundings statistically. The best-scoring candidate wins.

If no candidate clears the confidence threshold, the tool reports that it could not find a supported logo rather than applying a speculative correction. A refusal is more useful than a damaged image.

Multi-layer and repeated marks

Some exports carry the mark more than once — a file that has been through two generation passes, or a clip that was re-exported through a second tool, can end up with overlapping or stacked logos. A single-pass correction removes one layer and leaves a faint residue of the other.

The engine handles this with an iterative pass. After the first correction it re-examines the region for remaining watermark signature and, if it finds one, runs another detection and removal cycle. Each pass is scored independently, and the loop stops as soon as no further signature is detected, so clean images are never over-processed.

Single overlays are handled in one pass with no residue.
Stacked or repeated marks trigger additional passes automatically.
Each pass is quality-scored so a good result is never degraded by an unnecessary correction.
Processing stops the moment no further watermark signature is present.

Rights and reasonable use

Use this on images you own or are licensed to modify — your own model output, your own design work, assets your licence permits you to alter. Removing a mark is an editing operation, not a transfer of rights, and it should not be used to misrepresent the source of someone else's work.

Frequently asked questions

Can it remove a brand logo that is part of the scene?

No. It reverses alpha-blended overlays applied on export. A logo photographed inside the scene is real image content and would require generative fill instead.

Will there be a blurry patch where the logo was?

No. The correction recovers the underlying pixels and fades with the logo's own opacity, so there is no blur, box or halo.

What if the logo appears twice?

Multi-pass removal detects and corrects stacked or repeated marks automatically, stopping once no further signature remains.

Is there a file size limit?

Images up to 25 MB in PNG, JPEG or WEBP. The limit exists to keep browser memory use predictable, not because of any server.

Does the image get uploaded?

No. Everything runs in your browser tab — the file is never transmitted.

Is it free?

Yes. An account is required, but there is no usage cap or paid tier. Processing runs on your own hardware, so there is nothing to bill for.

Clear the corner, keep the image

Drop your file in and check the before/after slider. If the recovery is not clean, the tool will tell you rather than guess.
