How it works

Add your image
Drop a PNG, JPG or WebP image created with Gemini. It is decoded on your device and never uploaded.
Automatic detection
The sparkle logo is located from the image size and checked against its known shape. Fine-tune the position, size or strength if needed.
Download a clean PNG
The logo pixels are mathematically restored (not blurred or painted over), and the result is saved as a lossless PNG.

Only the visible logo
Google also embeds an invisible SynthID watermark in Gemini images. It cannot be seen, detected or removed by this tool, so the image can still be identified as AI-generated.
Metadata is not edited
The downloaded PNG is newly encoded, so the original file's metadata isn't carried over. To inspect or clean metadata in other files, use the Metadata Cleaner. Open the Metadata Cleaner →
Best on unedited images
Detection assumes Gemini's standard size and position. If the image was resized, cropped or compressed, adjust the controls; heavy JPEG compression can leave faint traces.
Use responsibly
Use it only on images you created or have permission to edit, and follow the rules of the platforms where you publish them, including any AI-disclosure requirements.
