Precise cropping without an app

Cropping is the quickest way to improve a photo: remove clutter at the edges, straighten the focus onto your subject, or cut an image to the exact shape a platform expects. Drag the frame and its handles, or type the X, Y, width and height when you need pixel-perfect results.

Pick a ratio such as 1:1 for profile pictures, 4:5 for Instagram, 16:9 for YouTube or the 35:45 passport shape and the box keeps that proportion while you resize it. The crop is taken from the full-resolution original and saved in its original format.

How to crop an image

  1. 1

    Open an image

    Choose a file, drag it in, or paste a screenshot.

  2. 2

    Pick a ratio (optional)

    Free, 1:1, 4:5, 4:3, 3:2, 16:9, 9:16 or Passport.

  3. 3

    Adjust the crop box

    Drag inside the box to move it and drag the handles to resize. Arrow keys nudge it; hold Shift for bigger steps.

  4. 4

    Crop and download

    Check the preview, adjust again if needed, and save.

Key features

  • Aspect-ratio presets

    Keep perfect proportions for social posts, thumbnails and ID photos.

  • Exact pixel input

    Type position and size for repeatable, precise crops.

  • Touch friendly

    Works with a finger on phones and tablets.

  • Full quality

    Cropping never scales your image; you keep every original pixel inside the box.

Common uses

  • Profile photos: Crop to a centred square for WhatsApp, LinkedIn or Google.
  • Passport and form photos: Frame your face in the 35:45 shape, then resize to the required pixels.
  • Screenshots: Cut out just the part of the screen you want to share.

Tips and good to know

  • After cropping, use the Image Resizer to reach exact pixel dimensions, then the Image Compressor for a KB limit.
  • To straighten a tilted horizon first, rotate by a small angle with the Image Rotator.
  • Cropping a photo removes the cut-off area permanently in the new file — your original file is not changed.
