Remove the Gemini sparkle watermark from your AI-generated images. One free image per day for signed-in users.
This tool is free, but requires an account to prevent abuse. One image per user per day.
Images generated by Google Gemini (including Nano Banana and Imagen-powered outputs) are stamped with a small colorful sparkle logo in the bottom-right corner. It marks the image as AI-generated and identifies Gemini as the source. For creators who want to use their own generated images in thumbnails, ads, or social posts, the logo often gets in the way of otherwise clean output.
This tool removes the visible sparkle logo from images you generated yourself. It does notremove SynthID — Google's invisible, pixel-level watermark used to detect AI-generated content. SynthID exists for safety and misinformation detection, and removing it is out of scope.
Drop in the Gemini-generated PNG, JPEG, or WebP file. Max 15MB. Stays in memory — we never store it.
The watermark region is replaced by sampling pixels from just above it. No AI upload, no third-party API, no round trip to another server.
Get your cleaned PNG instantly. Same dimensions, no visible sparkle, ready for whatever you were making.
This tool is free but requires a tinykit account and is limited to one image per user per day. That's intentional — it keeps the tool free and stops abuse, so we don't have to add a paid tier.
Only use this on images yougenerated. Don't use it to pass off AI content as human-made work at scale — that's against Google's terms, and it's the reason watermarks exist in the first place.
No. SynthID is Google's invisible, pixel-level watermark designed to detect AI-generated images. This tool only removes the visible sparkle logo. SynthID removal is intentionally out of scope.
The tool is free and has no paid tier. Requiring a tinykit account lets us enforce a one-image-per-day limit to prevent abuse and keep the tool sustainable for everyone.
Your image is processed in memory on our server and never written to disk. Nothing is sent to any third-party service. Only usage metadata (file name, size, dimensions) is logged to enforce the daily limit.
PNG, JPEG, and WebP up to 15MB. The output is always PNG to preserve quality. Minimum image dimensions are 300×300 pixels.
Server-side image processing isn't free, and keeping this tool free with no price tier means we need a fair-use cap. One image per day is enough for most creators to clean up a hero asset without the tool being gamed.
