How it works

Complete the job in three clear steps

  1. Choose a JPG, PNG, WebP, or BMP photo.
  2. Set the available options and create an annotated PNG and face-coordinate report.
  3. Review and download or copy the result before leaving the page.

Important

Check the result before relying on it

Keep an untouched copy of important source files. Browser processing depends on available device memory, and you should inspect every downloaded result before deleting the original.

Practical details

What this Lucaden tool does

MediaPipe's BlazeFace short-range model runs against local pixels, then Lucaden draws reviewable boxes without identifying, recognizing, or uploading anyone.

The original stays unchanged; Lucaden creates a separate result in browser memory.

Questions

About this tool

Does it identify people?

No. It only estimates rectangular face locations. It performs no recognition, identity matching, demographic inference, or biometric search.

Can it miss a face?

Yes. Side profiles, occlusion, small faces, unusual lighting, and stylized images can be missed or falsely marked. Review the entire source image manually.
