Side-by-side comparison
| Visible Gemini watermark | SynthID | |
|---|---|---|
| Can you see it? | Yes, a small sparkle near the bottom-right corner | No, it is hidden in the pixels |
| Purpose | A quick visual label | Lets Google-provided tools identify AI-generated content |
| Where it lives | One small area | Spread across the whole image |
| Designed to survive edits? | No, cropping removes it | Yes, designed to withstand common edits such as cropping and compression |
| Removed by Imaginoa? | Yes | No |
The visible sparkle
The sparkle is a semi-transparent white shape blended into a corner. Gemini has used an older, brighter version close to the corner and a newer, fainter version placed further in. Because the mark is blended with a known shape and strength, tools like Imaginoa can reverse the blend and restore the original pixels.
SynthID
SynthID is Google DeepMind's invisible watermarking technology. Instead of a logo, it makes tiny changes throughout the image that people cannot notice but detection tools can. It is built to remain detectable after everyday edits, which is why removing the visible sparkle does not change whether the image can be identified as AI-generated.
Why this matters
- For creators: removing the sparkle can make a thumbnail or slide look cleaner, but the image is still AI-generated.
- For honesty: be open about AI images where your audience, client or platform expects it.
- For rights: only edit images you created or have permission to change.
Free and private. Your image never leaves your device.
FAQ
Does Imaginoa remove SynthID?
No. It only removes the visible sparkle.
Can SynthID be seen?
No. It is invisible to people and is meant to be read by detection tools.
Does cropping remove SynthID?
SynthID is designed to withstand common edits such as cropping and compression.
Is it okay to remove the visible watermark?
Only on images you created or have permission to edit, and be open about AI use where it is expected.
