Questions people ask
How does the AI image detector work?
You upload a JPG, PNG, WebP, or HEIC image, and multiple detection engines look for generation artifacts, noise patterns, and metadata to produce a combined AI likelihood score from 0 to 100%.
Is PixelSniff free to use?
Yes, guests get 10 free basic analyses a day, and signing up for the Free plan adds 10 credits valid for one month for basic or deep analysis.
Do I need to sign up to check an image?
No, sign-up is not required to run a check, though signing in lets you buy credit packages, keep check history across devices, and run signed-in checks first.
Which image formats and sizes are supported?
JPG, PNG, WebP, and HEIC files up to 50MB can be uploaded for checking.
What kinds of AI images can it detect?
It can identify images from generators such as Midjourney, DALL·E, Stable Diffusion, Flux, and Gemini, as well as deepfakes, face swaps, and AI-edited or inpainted photos.
