About the Image Cropper
Crop an image by dragging a selection over it, or by typing the exact pixel coordinates when you know precisely what you need. Both work on the same selection, so you can drag roughly into place and then correct the numbers.
The crop is always applied at the image's natural pixel size, not at the size it happens to be displayed at. A 6000-pixel photograph shown 900 pixels wide on screen still crops to exact original pixels — which is why the numbers you type are the numbers you get, on any screen and at any zoom.
Lock the selection to a ratio when the destination has one: square for a profile picture, 16:9 for a video thumbnail, 9:16 for a story, 3:2 for print. A locked ratio is kept while you drag any handle, and it will never push the selection off the edge of the image — it shrinks to fit instead.
Output is PNG by default, which loses nothing. Choose JPEG for a photograph where the file size matters. Everything runs on your device: the image is decoded, cropped and re-encoded in your browser, and nothing is uploaded.
How to use the Image Cropper
-
Add an image
Drop it onto the box or click to choose. It appears with a selection already placed in the middle.
-
Drag the selection
Drag inside it to move it, or drag any corner to resize. The pixel coordinates update as you go.
-
Lock a ratio if you need one
Square, 16:9, 9:16 and the rest. The selection keeps that shape while you drag, and shrinks rather than overflowing at the edges.
-
Crop and download
Choose an output format — PNG keeps everything, JPEG is smaller for photographs — then download the result.
Frequently asked questions
Does cropping reduce the quality of the image?
Cropping itself removes pixels and changes nothing about the ones that remain. What can cost quality is the re-encoding: saving as JPEG applies lossy compression again. Choose PNG to avoid that entirely, or JPEG at 90 per cent or above, where the loss is not visible.
Why are the pixel numbers different from what I see on screen?
They are not — they are the original image's pixels rather than the size it is being displayed at. A 6000-pixel-wide photo shown 900 pixels wide on your screen is scaled down for display only. Cropping at the natural size is what makes the result sharp and the typed numbers exact.
What size should a profile picture be?
Square, and at least 400×400. Most platforms display it as a circle, so keep the important part well inside the middle — a face centred with room around it survives the crop; one filling the frame loses its edges. The square lock here matches what every platform expects.
Can I crop to an exact size in pixels?
Yes. Type the width and height into the fields and the selection resizes to match, keeping its position where possible. If the size is larger than the image it is reduced to fit rather than silently accepted — the tool cannot invent pixels that are not there.
Is my image uploaded anywhere?
No. Decoding, cropping and encoding all happen in your browser, and nothing is transmitted or stored. You can disconnect from the internet after the page loads and keep cropping.
