What happens to your file

A Gaussian blur whose radius is a per cent of the shorter side, so “medium” looks the same on a phone photo and a poster. The whole picture is blurred; the report says the radius in pixels.

Blurring one region — a face, a plate — is a separate tool. A heavy blur of a photo makes a good backdrop for a slide or a site header.

Questions

Is a blurred face safe to share?

Only at the heaviest setting, and even then not against every method. Pixelate at a coarse setting removes more.

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.effect",
    "options": {
      "effect": "blur",
      "strength": 2,
      "format": "same"
    }
  }'

The same operation, image.effect — Four small edits: rounded corners (with transparency), a border, a pixelation, a blur — sizes as a per cent of the shorter side. Upload first with the quickstart; every option is on the operations page. 500 free credits a month, then $5 per thousand.
