Is this profile picture AI? Checking dating and social profile photos
A file check can sometimes find a signed record or a label inside a picture. A photo shown on a profile may be a copy, and companies say screenshots, file conversions and re-uploads can remove such signals. So "nothing found" can be the result, and it proves nothing about the person or the photo. We do not judge faces.
Can you tell from a face whether a profile picture is AI?
Not in this guide. We do not describe face details, skin, hands or backgrounds as clues, because that is guesswork and it can wrongly accuse a real person. Our checker never looks at what a face looks like. It reads the file: whether a signed record is inside, whether the metadata names a source, and whether one known invisible pattern is present.
That is a narrow kind of evidence. It can help when a signal is there. When it is not, it says very little.
Why might a profile photo come back with nothing?
Three companies describe the problem in their own words.
- OpenAI. Its help article on provenance signals says Content Credentials can be lost through everyday actions, such as taking a screenshot or converting a file. It says its SynthID watermark is designed to withstand common changes, but heavy cropping or file compression can make a watermark undetectable. We do not read SynthID.
- Midjourney. Its Content Authenticity page says the small ID tag hidden in its images is easily lost: screenshots, edits and most social media sites remove it. It advises checking the original downloaded file, not a copy from social media.
- TikTok. Its newsroom post of November 19, 2025 calls it a common industry challenge that AI-content labels may be removed when content is reuploaded or edited elsewhere.
A photo you see on a dating or social profile has been uploaded and shown by an app, so it may not be the original file. We did not test any platform's upload process, so we cannot say what a given app does to a photo. The companies' own words above are the reason to expect losses.
What did we measure about lost signals?
We tested what an ordinary re-save does to the signals our checker reads. These are results about our test files, not about any platform or any person.
The invisible pattern. We marked PNG files with the Stable Diffusion watermark, the one invisible pattern our checker decodes. As PNG, we found the mark in 7 of 7 files. We then saved the same files as ordinary JPEGs, with the usual 4:2:0 chroma subsampling, at quality 90 and at quality 75. We found it in 0 of 14 of those files. The calibration was measured on October 27, 2026 in Chrome. The watermark results are on our accuracy page.
Re-drawing the picture. On October 30, 2026 we also drew each test file onto a browser canvas and wrote it out again as a PNG and as a JPEG (quality 0.92), which is similar to what a screenshot or an export does to the pixels. The table shows what our checker then read.
| Test files | Re-saved as PNG | Re-saved as JPEG |
|---|---|---|
| 9 real files with a Content Credentials record | Record read in 0 of 9 | Record read in 0 of 9 |
| 20 files marked with the Stable Diffusion watermark (9 PNG, 11 JPEG without chroma subsampling) | Watermark found in 19 of 20 | Watermark found in 0 of 20 |
All 18 re-saved copies of the record files read "No supported provenance signals found". The one marked PNG that was not found after the PNG re-save carries a colour profile; we did not test why.
Limits: one browser, one JPEG quality, no resizing, and a set of files we hold. No platform was contacted. Our test shows that a re-save can remove signals. It does not show that any particular profile photo was re-saved.
What should you do before checking a profile photo?
Use the best copy you can get. OpenAI says that, when possible, a check should use the original exported file and that an image should not be cropped or converted first. Midjourney gives the same advice about original downloads. A screenshot is a copy that OpenAI says can lose Content Credentials.
If you are talking to the person, you can ask for another photo or for the original file. That is a normal request. Our guide on how to verify a photo someone sent you has a checklist. A reverse image search can show where else a picture appears, which is a different question from how it was made.
Does a clean result mean the person is using real photos?
No, and a result that finds a signal is not a verdict on a person either. Photos can be edited, filtered, cropped or made with an app for many ordinary reasons. A provenance signal, when present, describes a file. It does not describe the account holder or what they intended.
OpenAI makes a similar point about its own checker: even when no signal is detected, consider the file's source and context before drawing a conclusion. We agree. Treat a missing signal as no information, and a found signal as one attributed claim to weigh with others.
What this means when you check an image
Open the checker, choose the file, and look at the headline. For a profile photo saved from a page, a headline you may see is "No supported provenance signals found".
It means we found no signed record, no source label in the metadata and no Stable Diffusion watermark pattern, and that every check ran. The line under it says this does not mean the image is real or human-made, and that most images lose these signals when they are shared, screenshotted or re-saved. The checker's fixed limits line also applies: these checks cannot determine whether an image is AI-generated.
The checker does not read Google's SynthID watermark, Meta's watermark, Adobe TrustMark, visible marks or Midjourney's hidden tag, and it does no pixel-based AI detection. If you have the original file from a particular maker, that maker's own checker may read signals ours cannot. OpenAI's verification page and Midjourney's verification page are two examples. They open another company's site and your image is uploaded to them, not to us. OpenAI's page asks you to agree to its terms when you upload, and Midjourney's help page says its checker needs no account. Our Privacy and method page explains what our own checker does with your file.

Frequently asked questions
- Is my match using AI photos?
- A file check cannot answer that. If a signed record or a metadata label is present, our checker shows it as a claim. If nothing is found, that can happen with a shared copy and it does not point either way.
- Does "No supported provenance signals found" mean the photo is a real photograph?
- No. It means we found none of the signals we read. The companies' pages above say these signals can be lost when a file is screenshotted, converted, edited or re-uploaded.
- Can I check a profile photo by uploading a screenshot?
- You can, but a screenshot is a poor copy to check. OpenAI says Content Credentials can be lost by taking a screenshot, and Midjourney says screenshots remove its tag.
- Do you look at the face to decide?
- No. Our checker reads the file's records, metadata and one known invisible pattern. It does not judge faces or any visual detail of the picture.
