    Photo Humanizer forAI Images.

    Run the 10-layer pipeline locally in your browser. Seven visible passes handle the core detector signals, while three reserved refinement layers stay internal - output reads as a real photo.

    AI original vs humanized output.

    Same pixels to your eye. A completely different statistical fingerprint to every detector.

    Pipeline pillars

    What runs under the hood

    PRNU Sensor Fingerprint

    A synthesized Photo Response Non-Uniformity pattern is injected so detectors classify your image as captured, not generated.

    FFT Frequency Disruption

    Diffusion models leave periodic artefacts in the frequency domain. Our FFT pass surgically scrambles those bands while staying perceptually invisible.

    Real-Camera EXIF

    iPhone, Pixel, Samsung and a generic DSLR profile — each with physically consistent ISO, aperture, focal length and GPS jitter.

    Provenance Metadata Removal

    Embedded provenance metadata — including Adobe C2PA manifests — is dropped on re-encode. An experimental SynthID-disruption pass is available but not guaranteed.

    Adaptive 10-Layer Stack

    Texture perturbation, colour decorrelation, chroma 4:2:0, JPEG double-compression, film grain, blur+sharpen — calibrated per image.

    Zero-Upload Privacy

    The full pipeline runs in a Web Worker on your device. Images never touch our servers.

    How it runs

    Three steps, all local

    01

    Drop image

    Drag any AI-generated PNG, JPEG or WebP onto the canvas — single file or batch.

    02

    Local processing

    10 layers run inside your browser via Web Worker. Typical: 3–6 seconds per image.

    03

    Authentic export

    Download a real-camera-equivalent JPEG with embedded EXIF, ready for any platform.

    FAQ

    Common questions

    Will humanizing hurt visual quality?

    No. Every layer operates at perceptually invisible amplitudes (sub-2 LSB on 8-bit channels). Output typically stays within 1–2 SSIM points of the original.

    Does my image get uploaded?

    Never. The entire pipeline runs locally inside a Web Worker. You can disable your network and processing still works.

    Which detectors does this target?

    It's designed to reduce the signals used by tools such as Hive, Sightengine, Optic, Illuminarty and AI-or-Not. No tool guarantees 100% — detectors evolve weekly, and so do we.

    What file formats are supported?

    PNG, JPEG, WebP and HEIC inputs. Output is always a real-camera-equivalent JPEG with embedded EXIF.
