Image Tampering Detection

ImgAuth is an AI-powered image authentication and forgery-detection platform. Upload a document photo, certificate, invoice, or other image, and we analyze it for signs of tampering—such as pasted regions, swapped content, or local edits—and return a heatmap so you can verify authenticity faster. The name reflects our focus: image authentication (ImgAuth) for teams that need trustworthy visuals.
