Question 1

What is a face shape detector?

Accepted Answer

A face shape detector is an AI-powered tool that analyzes your facial features to determine your face shape. Our tool uses MediaPipe technology to map 478 facial landmarks and classify your face into one of 7 shape categories: oval, round, square, heart, oblong, diamond, or triangle.

Question 2

How accurate is the face shape detection?

Accepted Answer

Our AI analyzes 478 facial landmarks across 5 dimensions (face shape, eye shape, nose shape, lip shape, and eyebrow shape) using a rule-based classification system. Accuracy depends on photo quality — a clear, front-facing photo with good lighting gives the best results.

Question 3

Is this tool completely free?

Accepted Answer

Yes, FaceShapeAI is 100% free to use with no signup required. There are no hidden fees, premium tiers, or usage limits.

Question 4

Is my photo safe and private?

Accepted Answer

Absolutely. Your photo is processed entirely in your browser using on-device AI. It is never uploaded to any server. You can verify this yourself by checking the Network tab in your browser's developer tools — you'll see zero image upload requests.

Question 5

What face shapes can be detected?

Accepted Answer

We detect 7 face shape types: Oval, Round, Square, Heart, Oblong, Diamond, and Triangle. We also support mixed face shape detection — if your face has characteristics of multiple shapes, we'll show both your primary and secondary face shape with confidence percentages.

Question 6

What other facial features are analyzed?

Accepted Answer

Beyond face shape, we analyze 4 additional dimensions: eye shape (slope, size, and spacing), nose shape (width and length), lip shape (thickness and width), and eyebrow shape (arch and slope). Together, these 5 dimensions give you a comprehensive facial analysis.

Question 7

How should I take my photo for best results?

Accepted Answer

For the most accurate results: face the camera directly, use good even lighting, pull hair back from your face, maintain a neutral expression, and make sure only one face is in the photo.

Question 8

Can I use this on my phone?

Accepted Answer

Yes! FaceShapeAI works on all devices — desktop, tablet, and mobile. On mobile, you can either upload an existing photo or take a new one with your camera.
