    Results are indicative only — this tool uses lightweight browser-only heuristics, not forensic-grade analysis.

    • Format conversion (JPEG/PNG → AVIF/WebP) alters noise and frequency signatures and may increase false-positive rate.
    • Messenger compression (WhatsApp, Telegram, etc.) re-encodes and strips metadata — photos saved from chats may score as AI-generated even when real.
