AI images for Facebook — avoid the AI label and reach penalty.
Meta applies AI labels across Facebook using the same stack as Instagram. SynthGuard humanizes images locally so they post without the label and keep full distribution.
Meta's unified AI detection stack across Facebook and Instagram checks C2PA metadata, known model watermarks and a frequency-domain classifier. SynthGuard's Social profile handles all three in one browser-side pass — save the output as JPEG (Facebook re-compresses anyway) to preserve the injected signals through the upload.
How Facebook moderates AI
Meta unified its AI-content policy across Facebook and Instagram. It checks C2PA metadata, model watermarks (including SynthID), and a server-side classifier. Flagged images get an "AI Info" label and reduced reach.
Recommended workflow
- 1Open the photo humanizer at /humanizer
- 2Drop your AI-generated image
- 3Pick the "Social" profile
- 4Upload to Facebook normally
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.

Open the toolFrequently asked questions
Is Facebook's detection the same as Instagram's?+
Yes — Meta uses a unified stack. SynthGuard handles both with one pass.
Does the AI label reduce reach on Facebook?+
Labeled content is deprioritized in some surfaces. Preventing the label keeps full distribution.
What about Reels and video?+
Use the video humanizer at /video-humanizer.
Is this against Meta's terms?+
Meta requires labeling realistic AI depictions of real events or people. Personal and creative AI art has no labeling requirement under current policy.

Use cases
More platforms
Instagram's AI-content labeling system flags synthetic images automatically and reduces their reach. SynthGuard humanizes images locally so they ship without the AI label and stay in the recommendation algorithm.
OnlyFans
OnlyFans bans AI-generated content unless the creator is verified as the depicted person. SynthGuard's image humanizer makes synthetic content indistinguishable from camera output for the platform's classifier.
Fanvue
Fanvue allows AI creators but requires labeling. SynthGuard humanizes images for creators who want to skip labeling without triggering the platform's auto-detection.
TikTok
TikTok labels AI content automatically and demotes it from the For You Page. SynthGuard humanizes images and videos so they ship clean.
Many subreddits run automod bots and Hive Moderation to auto-remove AI content. SynthGuard humanizes images so they pass both.
Etsy
Etsy requires AI-generated products to be labeled and applies search penalties. SynthGuard humanizes product photos so they pass as photographic.
