Did this image come from a active Valhalla generation?
Paste an image URL — anywhere on the web — and we'll check for our invisible signature. The signature is embedded into the pixels themselves, so it survives screenshots, JPEG compression, brightness shifts, and cropping.
How it works.
Every image generated through Valhalla has a 32-bit identifier embedded directly into its pixels using a neural-network watermarking algorithm (rivaGan). You can't see it, but a specialized decoder can.
If your image was generated through Valhalla, the decoder pulls out the identifier and we look it up in our database — returning the twin it was generated from, the creator who active it, the buyer who paid for it, and when. If your image isn't ours, you get a clean "no match" response.
The watermark survives the most common ways people strip provenance from images: screenshots, re-saves, JPEG re-encoding (down to quality 60), and crops up to ~20%.
