Image Cropper
Free image cropper. Drag a box over the picture to keep only the part you want, with optional fixed proportions for square, 4:3 or 16:9. Nothing is uploaded, so the picture never leaves your device.
What it does
Cropping keeps a rectangle and discards everything around it. Unlike resizing, nothing is stretched or averaged: the pixels that survive are exactly the pixels that were there, so a crop never softens the picture. What it does change is the shape, and that matters more than it looks — a photograph cropped to a square is a different photograph, because what you left out is as much a decision as what you kept. The faint grid over the selection marks the thirds, which is the oldest rule of thumb there is for where to put the subject.
How to use it
- Choose a picture from your device. It is read in the browser and goes no further.
- Drag across it to select the area, or type the exact numbers.
- Check the result below and download it.
Frequently asked questions
Does cropping lose quality?
The pixels you keep are untouched, so nothing is blurred or averaged. The only loss comes from re-encoding: saving a JPEG again always costs a little. Choosing PNG avoids that entirely, at the price of a much larger file for photographs.
Why are the numbers larger than the picture on screen?
What you see is a scaled-down preview, so a large photo fits on the page. The numbers are in real pixels of the original, and the crop is applied to the full-size picture — not to the preview. That is why the result can be far larger than what you were dragging over.
How do I get an exact square?
Set the proportions to 1:1 before dragging. The selection will then keep that shape whatever you do, and the width and height fields stay locked to each other. It is the safest way to prepare a profile picture, which almost every site crops to a square anyway.
Can I crop and resize in one go?
Crop here first, download the result, then open it in the resizer. Doing it in that order is deliberate: cropping decides what the picture is about, and only then does it make sense to decide how many pixels it needs.
Are my pictures uploaded anywhere?
No. The file is read by your browser and the crop happens on a canvas in the page. There is no upload and nothing is stored, and once the page has loaded it keeps working with the network switched off.
