What is Free AI Image Detector & Watermark Checker?

A free AI image detector that tells you whether any photo, screenshot, or artwork was created by artificial intelligence or captured by a real camera — and explains how it knows. It pairs visual forensics with a C2PA content-credential and watermark metadata check that most online AI image detectors skip, so you get real evidence instead of a bare percentage.

Key Features

  • Analyze any image in seconds — upload a JPG, JPEG, PNG, GIF, or WebP and get an instant AI vs. human verdict with a 0–100% confidence score.
  • Check C2PA content credentials & watermark metadata — detects embedded digital watermark signatures left by GPT Image, Adobe Firefly, and other C2PA-compliant generators on the original file.
  • Identify the generator — recognizes signature tells of Midjourney, DALL·E, Stable Diffusion, GPT Image, and Flux, and names the most likely model.
  • Flag deepfakes & partial edits — spots face swaps, AI outpainting, and AI-touched regions, not just fully generated images.
  • Explain every verdict — each report lists the specific artifacts, watermark findings, and confidence limits, so you can verify the reasoning yourself.

How to Use

  1. Upload your image — any JPG, JPEG, PNG, GIF, or WebP. Use the original file rather than a screenshot so the watermark metadata survives.
  2. Type "Start" — the detector runs a metadata watermark check and a full visual forensic scan of anatomy, lighting, texture, and structure.
  3. Read your report — a clear verdict, confidence score, evidence list, most-likely generator, and verification tips.

Example Use Cases

  • Journalism fact-checking — verify whether a viral photo circulating on social media is an AI-generated image before you publish or share it.
  • Recruiting & HR screening — check whether a candidate's portfolio headshot or product render is authentic or an AI photo that could misrepresent real skills.
  • Marketplace & e-commerce review — screen product photos and seller images for AI image detector red flags before approving a listing.
  • Deepfake defense — examine a suspicious video thumbnail or celebrity image for face-swap artifacts and AI-edited regions.
  • Social media moderation — quickly evaluate user-uploaded memes, event photos, and avatars for AI generation at scale.

Tips for Best Results

  • Always upload the original file, never a re-screenshot or platform-compressed copy — the C2PA watermark survives only on originals.
  • Higher resolution means higher accuracy. Heavily compressed or blurry images lower the confidence score, and the report will say so honestly.
  • One image at a time for the most detailed artifact analysis — then ask the agent to zoom into any suspect region.

FAQ

Q: What file formats are supported?
A: JPG, JPEG, PNG, GIF, and WebP. For the watermark metadata check to work, upload the original file rather than a screenshot or compressed copy.

Q: How accurate are the results?
A: Detection is probabilistic, not absolute. The agent gives an honest confidence score and lists the evidence behind it. Accuracy is highest on high-resolution originals and drops on heavily compressed or heavily edited images — the report tells you when confidence is reduced.

Q: How does this AI image detector compare to QuillBot's AI image detector?
A: QuillBot's tool relies purely on visual pattern analysis. This agent does that too, plus it checks C2PA content credentials and embedded watermark metadata — a deterministic signal that visual-only detectors miss — and it identifies the specific generator model and flags partial AI edits and face swaps.

Q: Can it analyze more than one image at a time?
A: For the most detailed results, run one image per check. You can then ask follow-up questions about a specific region or compare two images side by side.
