Remove the xAI Grok signature
Images from xAI Grok (Aurora) don't carry C2PA Content Credentials or a SynthID pixel watermark. Their only provenance signal is metadata: an EXIF 'Signature' blob plus a UUID Artist tag. RAIW detects and strips it for free - no GPU needed, and the pixels are never touched.
What Grok puts in its images
- An EXIF 'Signature' blob - a base64 string Grok writes into the image description field.
- A UUID Artist tag - a random identifier in the EXIF Artist field.
- Nothing else - unlike Gemini or ChatGPT, Grok images carry no C2PA manifest, no SynthID pixel watermark, no visible logo, and no IPTC 'Made with AI' tag.
How RAIW removes it
Because Grok's signal lives entirely in the file metadata, removing it is fast and free: RAIW strips the EXIF Signature and Artist fields (along with any other AI provenance metadata) on our backend, with no GPU and no change to the image pixels. The picture you download is the same image, just without the provenance trail.
Frequently asked questions
- Does removing the Grok signature change my image?
- No. The Grok signature lives in the file's metadata, not in the pixels, so RAIW strips it without re-encoding or altering the picture. The visible image stays exactly the same.
- Is removing the Grok watermark free?
- Yes. Grok's only signal is metadata, so the free mode handles it - there is no invisible pixel watermark to disrupt, so no GPU processing is needed.
- What image formats are supported?
- PNG, JPEG, and WebP. RAIW processes images, not video.
No signup required. Visible and metadata removal always free. GPU modes cost $1.25 per image. Supports PNG, JPG, and WebP.
