# IsThisImage — AI Image Detection Guide

> Check if an image is AI-generated with our free AI image detector. Upload a JPG, PNG or WebP. One free check daily, no signup required.

## How to check an image and understand its result
- Upload one JPG, PNG or WebP image, maximum 10 MB.
- Free usage: Yes. You can check one image per day for free, with or without an account. Your free allowance does not increase when you sign in.
- Process: Start with the original photo when possible. Simply choose a file or drag it in. Submit your image to look for patterns associated with AI generation. Get an easy-to-read assessment. Use it alongside the source and context.
- Results: Likely AI-generated, low AI signal, or uncertain — without turning probability into certainty.
- Important limitation: No. Detectors can make mistakes, including flagging real photographs or missing AI-generated images. Consider the original source, context and other evidence.
- Privacy: Images are processed when you submit them for a check, including by service providers necessary to return a detection result. We do not operate a public gallery of submitted images or ordinarily retain original uploads as a permanent customer image library. Limited processing or temporary retention may occur to deliver the service, protect against abuse or meet applicable obligations; independent providers may have their own retention practices. Do not upload images you are not authorized to submit or that contain unnecessary sensitive information. When you choose to continue through sign-in or payment, the browser may temporarily keep the selected image on your device so you can resume without uploading it again.
- Your image stays on your device until you start the check; the submitted image is analyzed using a third-party detection service.
- Detection scores and a likely generator are indicators, not proof of authenticity, authorship, ownership or wrongdoing.

## Frequently asked questions
### What does an AI image detector do?

It examines an image for patterns associated with AI generation. A result can help you investigate an image, but cannot prove its origin or authenticity.
### Is the AI image detector free to use?

Yes. You can check one image per day for free, with or without an account. Your free allowance does not increase when you sign in.
### Can it tell me for certain if an image is AI?

No. Detectors can make mistakes, including flagging real photographs or missing AI-generated images. Consider the original source, context and other evidence.
### Can I check a screenshot or an edited photo?

You can select JPG, PNG and WebP files. Screenshots, compression and heavy edits can remove useful signals, so an original image is preferable.
### Which AI generators can IsThisImage recognize?

IsThisImage can recognize signals associated with many major AI image generators, including GPT Image, Midjourney, Flux, Gemini, Imagen, Adobe Firefly, Stable Diffusion, Ideogram and others. Screenshots, compression or heavy editing can make detection harder.
### What happens to my image?

We respect your privacy. Your image is used only to complete the check, and IsThisImage does not store the original image in its own database or media storage.
