Do you look older or younger than you are? Upload a clear photo and an open-source AI model will guess your age. The guess comes with a range, because age estimation from a single photo is never exact. Your photo stays on your device the whole time.

Upload a clear photo of your face. An open-source age model estimates how old you look, with an honest margin of error.
- Your photo stays on your device. It is analysed in your browser and never uploaded to us or anyone else.
- Nothing is saved. Close the page or press "Remove my photo" and it is gone.
- Open-source models. Your browser downloads the model files once; see how our photo tools work.
How The Age Guess Works
The tool uses two small neural networks from the open-source face-api library. The first finds your face in the photo. The second, trained on thousands of photos labelled with real ages, outputs the age it thinks your face most resembles. We round that number and show a range of four years either side, which is a realistic margin for this kind of model.
Unlike the other PrismaTest photo tools, this one does not use the face landmark model. Age is learned from overall appearance (skin texture, facial fullness, the shape of features) rather than from measurements a person could check with a ruler.
Why You Might Look Older Or Younger
Perceived age, how old other people think you look, is shaped by many things besides your birthday:
| Factor | Effect |
|---|---|
| Sun exposure | Long-term UV exposure is a major cause of wrinkles and uneven pigmentation |
| Smoking | Associated with earlier wrinkling and duller skin |
| Sleep and stress | Can show as puffiness, dark circles and dull skin in the short term |
| Facial fullness | Fuller cheeks often read younger; weight loss can make a face look older |
| Grooming | Beards, glasses, hairstyle and make-up can shift age guesses by years |
| Expression | A 2015 study by Tzvi Ganel found smiling faces were judged slightly older, likely because of creases around the eyes |
Researchers take perceived age seriously. A study of Danish twins aged 70 and over, published in the BMJ in 2009, found that the twin who looked older was more likely to die first, suggesting perceived age reflects something about biological ageing.
How Accurate Is AI Age Estimation?
Honestly: roughly. Good models are often within a few years of the true age, but errors of five to ten years happen, especially when:
- the lighting is harsh, dim or coloured,
- the face is turned, partly covered or wearing heavy make-up or filters,
- the person is a child, a teenager or over about 60,
- the person belongs to a group that was under-represented in the model’s training photos.
Independent testing, including evaluations by the US National Institute of Standards and Technology (NIST), has found that age estimation accuracy differs between demographic groups. That is why we show a range, never use the estimate for anything important and never store it.
Get A Fairer Estimate
- Face the camera straight on, in soft daylight.
- Use a neutral expression and no beauty filter.
- Take two or three photos and look at the middle result.
- Compare an old photo and a recent one for fun: the change is often more interesting than the number.
Frequently Asked Questions
Can this tell my real age?
No. It estimates how old you look, which is a different and more variable thing.
Why did I get a different age from another photo?
Lighting, angle, expression and image quality all change what the model sees. Differences of several years between photos are normal.
Is this used to check ages anywhere?
Not by us. This tool is for curiosity only, it is not an age verification service and nothing is stored.
