Free AI Image detector
AI photo checker for a picture or a public image URL
Upload a photo, or add a link to a publicly available photo. This will give you a label for any file, whether it's a photo taken with a camera, an image generated or a photo that has been edited in parts.

Why use this AI image detector
A clean photo is not proof of a camera, and a strange one is not proof of a generator. Run the picture here and read the label before you decide.
Free AI photo checker
Open the page and check a picture. There is nothing to create first.
Upload or paste a link
Drop a JPEG, PNG, WebP, GIF, BMP, or TIFF, or paste a public image URL.
Three plain results
Real photo, fully AI-generated, or partly AI-edited, with a confidence percentage you can read.
The file, not the app
DetectGPT never opens ChatGPT, Midjourney, Gemini, or your camera roll. It only sees the picture you give it.
Public image URLs
A direct file link works. So does a Wikipedia file page. Private albums stay private.
Separate from the text checker
Writing and pictures are different checks. The homepage still scores a draft.

The tell
What the AI image detector looks at
The score comes from the pixels in the file you submit: texture, edges, and the even patches a generator tends to leave. No image app is opened, and the prompt that made the picture is not part of the check.
A crop, a screenshot, or a strong filter can move the label even when a person took the original. Treat the result as a clue, then look at the picture.
The number
How to read an AI photo result
Three labels, one confidence number. Real means the file looks like an unedited photograph. AI-generated means it looks synthetic across the frame. Partly edited means a photograph with an AI change in one area. The percentage is confidence in that label, not a ruling on the person who sent it.
Real photo
The file reads as a genuine, unedited photograph. Filters can still fool this.
AI-generated
The file reads as a fully synthetic image. That is a signal, not a signature.
Partly edited
A real photo with an AI change in part of the frame. Open the original if you have one.
False positives and false negatives happen. A DetectGPT image report is not proof of authorship. The free AI checker on the homepage is the separate check for writing.
Walkthrough
How to check a photo
- 1
Save the picture, or copy a public image URL. A Wikipedia file page is fine. A private album is not.
- 2
Drop the file into the checker, or paste the link under the box.
- 3
Stay under 10 MB. JPEG, PNG, WebP, GIF, BMP, and TIFF are the formats this page accepts.
- 4
Press Check image and read the label with the confidence percentage.
- 5
Look at the picture yourself before you treat the number as a decision.
Who it is for
Who the AI photo checker is for
Readers and editors
A quick look at a photo in a post, a listing, or a message before you treat it as a camera shot.
Students and teachers
A picture in a slide or a paper is not the same check as the writing. This page is only the picture.
Anyone sent a too-perfect photo
Use the score to slow down. It is not a reason, by itself, to accuse the sender.
Limits
What this checker cannot do
It cannot prove who made a picture.
It cannot name the generator or the camera.
It cannot open a private album, a login wall, or a chat.
It cannot scan a PDF, a slide deck, or a video. Use one image.
It cannot promise the same result after a crop, a screenshot, or a heavy filter.
It cannot check the caption. That is the text checker on the homepage.
FAQs
- Is this AI image detector free?
- Yes. No account and no card. Upload a photo or paste a public image URL. JPEG, PNG, WebP, GIF, BMP, and TIFF files up to 10 MB.
- How do I detect an AI generated image?
- Open the checker on this page, drop the photo in the box or paste a public image link, and press Check image. The report says whether the file looks like a real photo, a fully generated image, or a real photo with an AI edit.
- Can an AI photo checker tell which app made the picture?
- No. DetectGPT does not name ChatGPT, DALL-E, Midjourney, Gemini, Flux, or a phone camera. It scores the finished file. Two different generators can leave a similar look.
- What is the difference between real, AI-generated, and partly edited?
- Real means the file reads as a genuine, unedited photograph. AI-generated means it reads as a fully synthetic image. Partly edited means a real photo with an AI change in part of the frame. The percentage is how sure that verdict is, not proof of who made it.
- Can I check an image by URL?
- Yes, if the link is public. A direct image address works. A Wikipedia file link works. A private album, a login wall, or a page that is not an image will not.
- Will a screenshot or a heavy filter change the result?
- It can. Compression, screenshots, crops, and strong filters change the pixels the checker sees. Read the result as a signal, then look at the picture yourself.
- Is the AI image detector the same as the text checker?
- No. The homepage is a free AI checker for writing. This page is an AI photo checker. A caption and the picture next to it are different questions.
- Is an AI image score proof?
- No. False alarms and misses happen. Do not treat the percentage as proof of authorship, a newsroom ruling, or a reason to accuse someone.
