AI Image Checker: Verify Whether Any Photo Is Authentic
An AI image checker analyzes the forensic properties of a photo file to determine whether it was captured by a real camera or generated by an artificial intelligence model.
AI image checkers have become necessary tools as synthetic media floods social platforms, news feeds, and personal communications. A reliable AI image checker does not simply look at the image visually, it examines the file's forensic properties, including metadata presence and content, pixel-level noise characteristics, output dimension patterns, and color channel statistics. The ScanErase AI image checker runs all four analyses simultaneously in your browser.
What an AI image checker analyzes
A professional AI image checker examines four independent forensic signals. First, it parses the raw JPEG binary for EXIF metadata and inspects camera fields, software tags, and creation data. Second, it analyzes pixel-level sensor noise in flat image regions, the statistical signature of real camera sensors that AI generators cannot replicate. Third, it checks image dimensions against the database of known AI generator output sizes constrained by diffusion model architectures. Fourth, it measures color channel balance and distribution, which differs systematically between camera-captured and AI-generated images.
Browser-based vs. server-based AI image checkers
Most AI image checkers require you to upload your image to a remote server for analysis. This creates privacy risks, especially for images depicting people. Browser-based checkers like ScanErase process images locally using the Canvas API, meaning your image never leaves your device. Server-based checkers may use more sophisticated ML models but at the cost of your privacy. For most detection cases, browser-based forensic analysis is sufficient and significantly more private.
Limitations of AI image checking
No AI image checker achieves 100% accuracy. The technology is an ongoing arms race between generation models and detection algorithms. The most reliable cases for detection are images fresh from AI generators with no post-processing. Detection becomes harder when images have been compressed multiple times, had metadata stripped, or been modified after generation. For legal purposes, such as TAKE IT DOWN Act notices, you do not need to prove an image is AI-generated; you only need to assert that it depicts you in an intimate context.
When to use an AI image checker
Use an AI image checker when you encounter a profile photo that seems too perfect, a news image with suspicious detail, a photo that appears to depict you in a context you do not remember, or any image shared with the intent to harm, embarrass, or coerce. If the checker returns a high AI probability score and the image depicts you, contact ScanErase to initiate a removal scan.
Check any image with the free detector
Upload a photo to analyze its metadata, sensor noise, and pixel patterns. No account required. Your image never leaves your device.
Use free detectorFrequently asked questions
Is the ScanErase AI image checker free?
Yes, completely free. No account is required. All analysis runs in your browser and no payment is ever requested to check images.
What file types does the AI image checker support?
The checker supports JPEG, PNG, and WebP files up to 50 MB.
How accurate is the ScanErase AI image checker?
The checker achieves high accuracy on unmodified AI outputs from Midjourney, DALL-E, Stable Diffusion, and similar tools. Accuracy decreases for images that have been post-processed, converted between formats, or had metadata stripped. Results should be treated as forensic evidence, not a definitive determination.
