Remove SynthID from Nano Banana image exports
Google includes a mark on its documents named SynthID for the images which have been created using the above models. The name of the model will help you understand your source; however, it cannot help you make predictions about how your file can be processed.
Begin with the image you will actually use
Save the original output image and determine the right version of it to be used in your work. If there is more than one version of your edit - name them uniquely to avoid mixing the detector result with one of the early edits.
Inspect text and repeated details
Take a careful look at the graphics elements. Every word, comparison of repetitive objects and checking the small elements like lines, hands and background will help. For the product mock-up, do the analysis of the brand mark and the text on the packaging in the original scale.
Automatic image processing
Just apply your image file to our advanced image-processing engine and the standard process will happen automatically. Keep the original, compare it, pay attention to the important details and download the result when it fits.
Transparent image workflow
In case the processed image is a cutout, the original alpha channel mask stays there. Compare carefully the detailed edges and semitransparent areas. Save it in the PNG format or choose the white background as a background to make it fully flat.
Verify after export
The comparison view helps to see if everything is right. Independent detection checks if a supported signal is here. Test exactly this exported file, note the result and don't try to generalize one successful test of Nano Banana output.
High-resolution Nano Banana images
The original 2K/4K may itself be over the 2 MP limit we currently have set. Make sure to check the size prior to uploading, and then once you produce the lower size copy, save the original file for testing. An output at high resolution isn't automatically supported simply because the compressed file is below 4MB.
