What is image cropper?

Cropping removes the parts of a photo you do not want and sets the shape. Social platforms prefer certain shapes: square for profile pictures and posts, 9 by 16 for stories and reels, and 16 by 9 for video thumbnails.

This cropper works with presets and position controls. It uses the canvas of your own browser, so your photo never leaves your device.

How to use the image cropper

  1. Choose your image.
  2. Pick a shape, a zoom and the position.
  3. Press Crop image and download the result.

How the image cropper works

The tool finds the largest area of your image with the chosen shape. The area is then reduced by the zoom percentage and placed according to your position setting. That area is drawn onto a new canvas and saved as a PNG.

Worked example

A 4000 by 3000 photo cropped to a square at 100 percent gives a 3000 by 3000 image from the center.

Common uses of the image cropper

  • Profile pictures.
  • Instagram and Facebook posts.
  • Story and reel covers.
  • YouTube thumbnails.
  • Product photos.

Tips and common mistakes

Use a position setting to keep a face or subject inside the crop.

Lower the zoom to crop in tighter on the subject.

Background: what to know before you rely on it

Aspect ratio is the width divided by the height. Photos from cameras are usually 3 by 2 or 4 by 3, phones record 9 by 16 or 16 by 9 video and platforms often want a square. Cropping to the right shape yourself keeps control of the composition, instead of letting a platform cut your picture automatically. Keep the subject away from the very edges, since some apps round corners or overlay buttons. Crop first, then compress, to keep files small without losing the part that matters.

Private, free and fast
