Blur faces

Before the photo goes public: faces found by a detector and blurred, no boxes to draw.

More free conversions, where you upload. The Fylane extension does the same work inside any upload form, on its own free share every day.About the extension

How to blur faces

  1. Drop the photo.
  2. Pick the strength.
  3. Press Blur and download.

What happens to your file

YuNet, OpenCV’s face detector, finds every face at 640 px on Fylane’s servers; each box, widened a fifth for hair and chin, is blurred in place and the rest of the picture is untouched. The result keeps your format and its size.

A face it misses — turned away, tiny, in deep shadow — stays visible: the metadata says how many were found, and the box tool on Blur part of an image covers the rest by hand.

Questions

Does it keep the photo’s metadata?

Location and camera EXIF are dropped with the re-encode; the pixels outside the faces are as they were.

Can I choose which faces?

Not here — every face is treated. Blur part of an image takes one box you draw.

Do this in code

curl -X POST https://api.fylane.dev/v1/jobs \
  -H "Authorization: Bearer $FYLANE_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "file_id": "<file id>",
    "operation": "image.faces",
    "options": {
      "effect": "blur",
      "strength": 30
    }
  }'

The same operation, image.faces — Every face YuNet finds, blurred or pixelated (`effect`, `strength`, `margin`); the count and boxes in the metadata, and the picture unchanged when it finds none. Upload first with the quickstart; every option is on the operations page. 500 free credits a month, then $5 per thousand.
