Free AI Image Detector
Think an image may have been created or heavily modified with artificial intelligence? Upload it to NetQuill’s free AI image detector to screen it for AI-generation signals and available provenance clues.
AI Image Detector
Upload an image to check if it's AI-generated or natural.
Click to upload or drag & drop
Supports JPG, PNG, WEBP
Important: AI-image detection is not definitive. A detector can produce false positives and false negatives, particularly after editing, resizing, screenshots or compression. Treat the result as a signal for further investigation rather than proof of how an image was created.
How the AI Image Detector Works
User selects an image.
The image is analyzed by the visual detection model.
The tool evaluates patterns associated with synthetic imagery.
Available file/provenance information can provide additional clues.
The tool produces a result.
The result should be interpreted as evidence, not absolute proof.
Can AI Image Detectors Be 100% Accurate?
No AI image detector can guarantee that every image will be correctly classified. AI-generated images can be edited, resized, compressed, screenshotted or otherwise transformed, which can affect detection. Conversely, some genuine photographs can contain visual characteristics that cause a detector to produce a false positive.
How to Tell If an Image Was AI-Generated
1. Check the image with an AI detector
Open the Free AI Image Detector Tool
2. Examine hands and fingers
Not because this is definitive, but because AI-generated imagery can sometimes contain anatomical inconsistencies.
3. Look at text
AI-generated images can sometimes contain distorted or nonsensical text.
4. Examine reflections and shadows
Look for inconsistencies.
5. Check image metadata
Metadata may contain useful clues, although it can easily be removed.
6. Look for Content Credentials
Where available, provenance information can provide stronger evidence than visual guessing alone.
This makes the page genuinely useful rather than just being a wrapper around a tool.
AI Detection vs Image Metadata
AI detector:
Looks at visual characteristics.
Metadata:
Looks at information stored with the file.
Content Credentials/C2PA:
Can provide provenance information when a compatible workflow has created and preserved it.
Frequently Asked Questions
What is an AI image detector?
An AI image detector is a tool that analyzes an image for characteristics associated with AI-generated or synthetic imagery.
Is the NetQuill AI image detector free?
Yes. NetQuill’s detector is designed as a free tool and does not require a paid subscription to use.
Can an AI image detector tell if an image is definitely AI-generated?
No. Detection results should be treated as evidence or a probability signal rather than definitive proof.
Can AI-generated images fool detectors?
Yes. Editing, resizing, compression, screenshots and newer generation techniques can make detection more difficult.
Does uploading an image make it public?
For your tool, explain the actual implementation here. If the final detector continues processing entirely in the visitor’s browser, say so clearly.
Can metadata prove an image is AI-generated?
Not necessarily. Metadata can provide useful clues, but it can also be removed, changed or lost during image processing.
What types of images can I check?
List the actual formats your tool supports.
How accurate is the NetQuill AI image detector?
This is where you should publish the actual model’s independently reported performance and limitations rather than inventing an accuracy percentage.
