FAQ
What the tool supports
Visible corner marks, file metadata, and invisible watermarks have different processing requirements.
01Which watermark does this tool support?+
The current tool supports known visible or semi-transparent Gemini corner logos. It uses matching watermark templates and reverse alpha blending. Resized, cropped, heavily edited, or unfamiliar marks may be skipped.
02Does this remove SynthID?+
SynthID is a separate invisible watermark embedded in image pixels. This tool does not detect or remove it. Removing a visible corner mark or file metadata does not establish that SynthID is absent.
03Will my images be uploaded?+
Images are read and processed in a local browser worker. Watermark matching, PNG export, metadata cleaning, and output checks run on your device. No image processing API or account is required.
04Does image quality change?+
The tool edits pixels and exports an 8-bit sRGB PNG at the displayed dimensions. PNG export adds no JPEG compression, but the file is re-encoded: color profiles, high-bit-depth or HDR data, and file size can change. The original file is untouched.
05How is the result verified?+
The exported PNG is decoded again, its displayed dimensions are checked, and supported metadata is re-scanned using container checks and an independent EXIF/XMP/IPTC parser. The same watermark engine checks the output for another match. This is a heuristic recheck, not an independent guarantee; review the image visually.
06What if no mark is detected?+
Watermark edits are skipped when the engine cannot confidently match a supported mark. That can mean the mark is absent or unsupported. You can still export a PNG with supported metadata cleaned, or use the metadata-only cleaner to avoid re-encoding.
