How to Check if an Image Is AI-Generated
How to check if an image is AI-generated: what an AI image detector looks for, how to spot Midjourney, Stable Diffusion, and DALL·E output in seconds.
AI image generators like Midjourney, Stable Diffusion, and DALL·E now produce pictures that are hard to tell apart from real photos. A convincing fake can spread across social media, slip into a news story, or headline a marketplace listing before anyone questions it. If you need to know whether an image was made by a person or a model, an AI image detector is the fastest way to get an answer — and this guide walks through exactly how to check if image is ai generated, what an AI image detector looks for, and how much to trust the result.
What is an AI image detector?
An AI image detector is a tool that analyzes an image and estimates the probability that it was generated by an AI model rather than captured by a camera or drawn by a human. A good AI image detector returns three things:
- a verdict — likely AI, likely human, or uncertain
- an AI probability score — from 0 to 100%
- a confidence level — how much to trust the result
That combination matters. A raw yes/no answer hides how sure the model is, so a detector that reports a probability and a confidence level lets you weigh the result instead of taking it at face value.
How to spot AI images by eye
Before reaching for a tool, it helps to know the classic tells. When you are asking yourself "is this image AI or real?", look closely at:
- Hands and fingers — extra digits, fused knuckles, or impossible poses
- Text — warped, garbled letters on signs, labels, or clothing
- Reflections and shadows — light that falls inconsistently across a scene
- Fine repetition — jewelry, teeth, or patterns that repeat unnaturally
- Backgrounds — melting architecture or objects that blend into each other
These shortcuts still catch a lot of low-effort fakes. The problem is that they are disappearing fast: each new model generation fixes more of them. Relying on the naked eye alone gives you a false sense of security, which is exactly why a dedicated AI image checker is worth running even when a picture looks perfect.
What an AI image detector looks for
AI image detectors look beyond obvious visual mistakes and evaluate statistical patterns in the image signal that people may not notice:
- Frequency-domain artifacts left by diffusion and GAN upsampling
- Unnatural texture regularity in skin, hair, and foliage
- Telltale patterns in how edges and noise are distributed across the frame
These signals can add useful evidence when a synthetic picture has no obvious visual mistakes. They are not unique to AI images, however, and editing can weaken or change them. That is why the output is a probability rather than a claim about who or what created the image.
How to check if an image is AI-generated
Here's the step-by-step process for how to check if image is ai generated using our free tool.
Running an image through the detector takes only a few seconds:
- Open the AI Image Detector.
- Upload a JPG, PNG, or WebP file, or paste an image URL.
- Read the verdict, AI probability, and confidence level.
That's it — no account is required to try it. The submitted image file is processed for the requested check and is not added to detection history. See the Privacy Policy for processing and retention details.
For the cleanest first pass, use the highest-quality original file you can get. A social-media screenshot or repeatedly compressed copy may contain fewer useful signals than the source image.
How to interpret the result
Read the score, verdict, and confidence together. For example, a score of
0.52 falls in the uncertain range. It does not mean that the image is 52%
proven to be AI-generated, and it should not be rounded into a yes/no claim.
Instead, request the original file and check the source, metadata, provenance,
and reverse-image-search results before drawing a conclusion.
A high-confidence result is farther from the uncertain range, but it can still be wrong. The detection methodology explains the score and verdict thresholds, while accuracy and limitations covers false positives, false negatives, and the effect of image edits.
Using it as an AI image checker for specific generators
The same workflow doubles as a Midjourney detector, a Stable Diffusion detector, or a DALL·E image detector. One workflow returns a consistent AI-probability score across images associated with popular generators. Results vary by generator, image content, editing, and compression, so they should be used as one signal rather than proof.
How accurate is an AI image detector?
No detector is correct 100% of the time. Images that have been heavily edited, compressed, screenshotted, or passed through several apps are harder to classify, and newer or uncommon generation workflows may behave differently. Treat the AI probability score as one signal rather than proof: a high score can still be a false positive, and a low score can still be a false negative. For high-stakes decisions, pair the result with provenance, context, metadata, reverse-image search, and human review.
When to use an AI image checker
A quick check is worth the few seconds it takes whenever an image could influence a decision:
- Journalists and fact-checkers verify a photo before it runs in a story.
- Online daters confirm that a profile picture belongs to a real person.
- Marketplace buyers check that a listing photo wasn't synthesized.
- Recruiters and HR screen headshots and documents during onboarding.
- Artists and moderators confirm that work was actually made by a human.
In each case an AI photo detector provides a useful first-pass signal that helps you decide what evidence to check next.
Detecting at scale with the API
If you need to check images programmatically — content moderation, marketplace verification, newsroom pipelines — the same engine behind the AI image detector is available as an API. One call per image returns the verdict, an AI-probability score, and a confidence level, with usage-based pricing. See the documentation to get started.
The bottom line
No detector is a magic oracle, and you should treat the score as a probabilistic signal rather than proof. But when you need a structured first pass, running the image through a detector is more informative than relying on visual guesses alone. Try the AI image checker, then use the result to guide the rest of your verification process.
FAQ
How to check if image is ai generated for free?
You can check if an image is AI generated for free with AnyImageDetector. Upload a JPG, PNG, or WebP file, or paste a direct public image URL. The tool returns a verdict, an AI probability score, and a confidence label in seconds. Your first checks do not require an account.
Can Google detect AI generated images?
Google may use many signals across Search and other products, including metadata, provenance, and visual patterns, but there is no public Google tool that gives a universal AI image verdict for any uploaded file. For a direct check, use a dedicated detector and verify the source separately.
Can screenshots or compressed images change the result?
Yes. Screenshots, crops, resizing, social-media compression, and repeated JPEG saves can remove useful signals or add artifacts. For the most reliable first pass, use the highest-quality original image you can get, then compare the detector result with source and metadata checks.
Is an AI image detector result definitive proof?
No. AI image detection is probabilistic. A high score can still be a false positive, and a low score can still miss an edited or newer AI image. Use the result as one signal alongside metadata, provenance, reverse image search, and human review.
