How the AI Image Detector Works

This AI image detector runs entirely in your browser — no image is ever uploaded to a server. When you drop an image, the tool inspects the file on two levels. First, it reads embedded EXIF metadata looking for known AI generation software signatures from tools like Midjourney, DALL-E, Stable Diffusion, Adobe Firefly, and others. Second, it analyzes pixel-level patterns including color distribution uniformity, noise characteristics, and compression artifact signatures that are statistically more common in AI-generated images than in real photographs captured by a camera.

What Does the AI Detector Check?

Limitations of AI Detection

Browser-based AI detection gives you a directional result — not a forensic verdict. If a user strips metadata from an AI image before sharing, the detector loses its strongest signal. Highly compressed, cropped, or heavily edited AI images may return uncertain results. For high-stakes decisions such as journalism verification or legal proceedings, professional tools like Hive Moderation or Content at Scale exist for that purpose. Our tool is best used as a fast, private first-pass check for everyday content moderation and social media review.

How to Tell if an Image Is AI-Generated: A Manual Checklist

No single sign proves an image is AI-generated, and newer generators keep fixing the old giveaways. Still, a quick manual check alongside the detector helps:

Treat these as hints, not proof. Real photos can show some of them too, especially after heavy editing or compression.

Why Metadata Is Often Missing

Many apps and social platforms re-encode images when you upload or share them, and screenshots do not carry the original file data at all. When that happens the detector has nothing to read from the metadata and falls back to pixel patterns, which is a weaker signal. Some tools embed provenance information such as C2PA Content Credentials, but support varies and it can be removed. Read more in our guides to AI image metadata and Content Credentials and how accurate AI image detectors really are.

What to Do With the Result

Frequently Asked Questions

How can I check if a photo is AI generated for free?

Upload the photo to the detector. It reads the file's metadata for AI tool signatures and analyzes pixel patterns, then shows an estimate. It is free, needs no signup and runs in your browser. Treat the result as one signal, because stripped metadata or heavy editing can hide AI images.

Is there a free AI photo detector that does not need signup?

Yes. This detector is free, has no signup, and works on JPG, PNG and WebP files. No detector is perfectly accurate, so use it together with the manual checklist on this page and the image's original source.

Is this AI detector 100% accurate?

No. Browser-based analysis gives a directional result, not a guarantee. Accuracy is highest on uncompressed original files with full EXIF metadata intact. Images that have been resaved, cropped, or had metadata stripped will produce less certain results.

What image formats does the AI detector support?

JPG, PNG, and WebP are fully supported. For best results, use the original uncompressed file directly from the AI generator or camera before any editing or re-export.

Does the AI detector upload my image?

No. All analysis runs entirely in your browser. Your image is never sent to any server and never leaves your device. This is the same privacy-first approach used across all TinyPNG Now tools.

Can it detect Midjourney, DALL-E, and Stable Diffusion images?

Yes. The detector specifically looks for metadata signatures from Midjourney, DALL-E, Stable Diffusion, Adobe Firefly, Flux, and other major AI generators. Detection is most reliable when original file metadata has not been stripped or modified.

Can the detector tell which AI tool made an image?

Only when the file metadata names the software, for example a generator signature in the EXIF or XMP fields. Without metadata it can only estimate from pixel patterns and cannot name the tool.

Does it work on screenshots?

Screenshots usually lose the original metadata, so only pixel-pattern analysis is left and the result is less certain. Use the original file whenever you have it.

Is my image uploaded anywhere?

No. The analysis runs in your browser and the image is not uploaded to a server.

Also need to compress or convert your images? Try TinyPNG Now's free image compressor — no upload, no signup required.

Free AI Image Detector -- Check if a Photo Was AI Generated

Detect whether an image was generated by AI (DALL-E, Midjourney, Stable Diffusion, Firefly) or captured by a real camera. Analyses metadata signatures and pixel-pattern artifacts to give a confidence score in seconds.

Detects Major AI Tools

Looks for metadata signatures and pixel patterns associated with DALL-E, Midjourney, Stable Diffusion, Firefly, and others.

Confidence Score

Returns a likelihood score, not just a yes/no, so you can judge borderline cases. It is a heuristic, not a verdict.

Metadata Analysis

Checks EXIF data for AI-generated image flags left by some tools like Adobe Firefly.

Private and Free

Detection runs in your browser. No image is uploaded to a server.

Frequently Asked Questions

How accurate is AI image detection?

Accuracy varies widely by image and tool, and no detector is reliable on its own. This tool is a heuristic that works best on original files with intact metadata; edited, filtered, resized or screenshot-compressed images are much harder to judge.

Can this detect Midjourney images?

Sometimes. The detector mainly looks for generator metadata and some pixel patterns, so it can miss images whose metadata was stripped.

What should I do if the detector says AI-generated?

A positive result means the image likely has AI origin. A high confidence score on an unedited image is a strong signal. A low confidence score on a filtered photo is less conclusive.

Does this tool detect AI-edited photos, or only fully AI-generated ones?

Primarily fully AI-generated images. Photos that have only been lightly touched up with AI tools may not trigger a positive detection.
