AI images for Facebook — avoid the AI label and reach penalty.

Meta runs one AI-detection stack across Facebook and Instagram, so what fires on one fires on the other. Every image upload is checked for C2PA provenance, known model watermarks, and a frequency-domain classifier score.

C2PA is the easy part — most generators inject it and SynthGuard strips it before any pixel processing. SynthID is harder, because it's a robust watermark embedded in the pixels; the SynthID disruption layer breaks its synchronization without visible quality loss.

The classifier is the strongest signal. SynthGuard's FFT disruption, PRNU injection, and texture perturbation layers target the exact frequency and noise characteristics it scores. The Social profile is the right default for Facebook's moderate-strength classifier.

Facebook re-compresses uploads to JPEG, so save your humanized output as JPEG to avoid a second transform that could weaken the injected signals.

Browser-only means your image is never uploaded to a humanization server — the only place it goes is Facebook, when you choose to post it.
