How it works

  1. Drop the photo. Portraits with the face near the centre work best because LINE shows the picture as a circle.
  2. Fill and crop is preselected: the photo is scaled to cover the 640×640 square and the sides or the top and bottom are trimmed around the centre.
  3. Press Resize for LINE. The output is exactly 640 by 640 pixels.
  4. Set it under Home, profile, photo. Anything in the four corners of the square is hidden by the circular mask.

Frequently asked questions

Why 640 × 640?
LINE displays profile pictures as a circle cut from a square. 640×640 is large enough for the profile screen and sharp at 2× in chat lists, while staying small enough that LINE barely has to scale it down.
What is hidden by the circle?
A circle inscribed in the square hides about 21% of the area, all of it in the corners. Keep faces, logos and text inside a circle that touches the four sides.
The face is off to one side.
Fill and crop always crops around the centre. Use Crop image first to position the face, then run this preset.
JPG or PNG?
JPG for photos. PNG for illustrations or logos with flat colour; LINE converts both, but PNG keeps the edges cleaner before conversion.
Is my photo uploaded anywhere?
No. It is resized in your browser and never sent to Nouplo. The free plan allows 3 files per run, 20 MB per file and 10 runs per day; Pro removes those limits.
