Blur image

A Gaussian blur across the frame: a backdrop, a placeholder, a hidden detail.

  2. Pick how much blur.

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 it once, not on every form

A form that wants a square JPEG under 240 KB says so on the page. The Fylane extension reads that, fits your photo to it, and puts it in the field — without you working out what 240 KB looks like.

And it keeps the result. The next application that asks for a résumé, a cover letter and a photo fills all three from one tap, each one refitted to what that site accepts.

Your files stay in the browser, encrypted, on your machine. Nothing is uploaded to keep them and nothing is sent anywhere to fill a form.

Filmed from the extension: a phone portrait against a form that takes only a square JPEG under 240 KB.

Add to Chrome — freeWhat it does

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.
