How to crop by eye

  1. Drop the image.
  2. Pick the box by eye and drag it.
  3. Press Crop and download.

What happens to your file

The box you drew is turned into the picture’s own pixel coordinates — a box on a 1600 × 1200 photo is measured in those pixels, whatever size the screen shows — and libvips cuts exactly that region out, with nothing scaled. The format stays as it was unless you choose another.

Crop image (the other page) cuts to a shape — square, 16:9 — centred or from an edge. This one is for the box only you can see.

Questions

Can I type the numbers?

The readout under the picture shows them; dragging is the way to set them. Precise pixel entry is on the list.

Does it work on a phone?

Yes — the box and its corners take touch. Pinch to zoom the page if the picture is small.

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.

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.crop",
    "options": {
      "format": "same"
    }
  }'

The same operation, image.crop — Crop by coordinates, or centre-crop to an aspect ratio. Answers WebP unless `format` says otherwise. Upload first with the quickstart; every option is on the operations page. 500 free credits a month, then $5 per thousand.
