Visible bottom-right Gemini overlays only. Transparent, animated, resized or cropped images may be skipped. Uncertain detection keeps your original. No SynthID or C2PA removal; no general copyright watermark removal.
A little math. A careful check.
Check the overlay
Match calibrated Gemini templates near the bottom-right corner. If the evidence is uncertain, keep the original.
Reverse the blend
Use an open-source inverse alpha blend to estimate the pixels beneath the visible overlay. No generative fill or model API.
Review & download
Slide between the original and processed version. Inspect the corner at full resolution. Download a PNG or a batch ZIP.
Questions,
answered plainly.
Which Gemini watermarks can this clean?
This MVP targets known visible sparkle overlays at their original bottom-right positions in opaque still images. It uses a conservative subset of the pinned open-source image pipeline. Screenshots, re-compressed, resized or cropped images, new overlay designs and complex backgrounds may be skipped. It does not verify that an image came from Gemini.
Is the result lossless?
No. Inverse blending estimates covered pixels. Compression, rounding and clipped colors can prevent exact restoration. Output is a newly encoded, edited PNG, so file bytes and some source metadata may change or be omitted. Review each result and retain the original.
Where do my images go?
Your images stay in this browser session. There is no upload endpoint, analytics, account, remote model or cloud storage. Only application assets load from the host. Clear the batch or close the page to release image references. Downloads stay wherever your browser saves them.
Does it remove SynthID or C2PA?
There is no dedicated SynthID or C2PA removal or verification feature. This tool only targets the visible overlay. Editing and PNG re-encoding may affect invisible signals or omit source metadata, including Content Credentials; their preservation is not guaranteed. Source signatures are not copied or recreated. Original downloads preserve the exact input file. It is not a tool for other copyright watermarks.
Why was my image left unchanged?
No reliable template match, low confidence, transparent pixels, unsupported format, potential content damage or a processing failure can all keep the original. Each image includes a reason. Skipped images are never included in the cleaned ZIP; their original downloads preserve the exact input bytes.
What has actually been tested?
Automated tests cover synthetic overlays, negative images, transparency, limits and batch lifecycle. Synthetic tests are not proof of real Gemini image quality. Real-world image quality and all browsers have not been comprehensively validated. This is an early MVP.
